description: In Ethiopia agency banking is an infant technology and has many challenges not only for service providers but also for the customers. This study tried to identify and investigates those factors which influence customers' intention to uptake agency banking service in Ethiopia. The study employed explanatory research design. The research model includes the basic concepts of the Unified Theory of Acceptance and Use of Technology (UTAUT), as well as some constructs derived from other theoretical frameworks. Accordingly, Performance expectancy, effort expectancy, Perceived risk, public Trust on agency banking and service quality were specified as a determinant factors of customer's intention to adopt agency banking service. Each variable is measured using 5-point Likert-scale. Using primary data collection method, questionnaires were distributed to target respondents of sampled customers of Commercial Bank of Ethiopia, United Bank S.C., Lion International Bank S.C and Cooperative Bank of Oromia applying judgmental or purposive sampling technique. Out of the total 399 questionnaires distributed, 362 useable questionnaires were obtained. Ordinal regression analysis was made using Stata version 13 whereas descriptive statistics analysis was done through Statistical Package for Social Sciences (SPSS) version 20. The findings of this study revealed that Performance expectancy, effort expectancy and Perceived risk were the significant factors affecting customer's intention to adopt agency banking service whereas, public trust of agency banking and service quality of service providers and agents were found to be insignificant factors in this study. The study suggests a series of measures which could be taken by the banking industry. The study recommends that financial institution needs to sensitize customers about the performance, perceived risk and ease of use of agency banking service. Financial institutions should also conduct extensive promotion; marketing and cross-selling activities in order to attract new customers and increase their customer base from untapped potential of availability of highly intended users to adopt the service. Banks should also provide training and education to their employees and agents on agency banking service in order to attain better service quality, gain public trust and ultimately encourage the participation of intended users.

description: ABSTRACT One of the most attracting renewable sources for energy production is bioethanol, which can be obtained from biomass. Special attention is here focused on the steam reforming reaction of ethanol (SRE) in which the principal product, hydrogen, is an interesting energy vector to produce power, electricity and heat. However, the process has not yet come to maturity and it should be optimized in order to made it industrially available. To this aim, we focused our work on catalysts synthesis for SRE, trying to couple high activity and durability. Different catalyst formulations based on Ni as active phase, supported over zeolite-BEA, zirconia, titania and lanthana were synthesized and characterized by N2 adsorption/desorption, temperature programmed reduction (TPR), X-rays diffraction, transmission electron microscopy and infra-red Fourier transform spectroscopy. The performance of the catalysts was evaluated for SRE by using absolute ethanol and bioethanol 50 and 90 vol%, obtained from second generation biomass and kindly supplied by Mossi&Ghisolfi. An important aim of the work was the intensification of the process from the energetic point of view, decreasing the energy input to the reformer (endothermal reaction) to better integrate this high temperature stage with the hydrogen purification section and the possible use of Proton Exchange Membrane Fuel Cells (PEM-FC).

description: This paper presents hardware-only and real-time based methods to test and investigate PV inverters in an accurate way. Based on existing requirements for grid-connected and islanding operation modes of inverters, test procedures are well-defined and described in standardization frameworks. The increasing complexity and the rising test effort of many tests ask for alternatives to widely used hardware-only testing methods in order to be able to optimize the testing time without compromising the accuracy of results. In recent years, respective alternatives are identified as real-time based simulation topologies such as the controller hardware-in-the-loop (CHIL) or the power hardware-in-the-loop (PHIL) simulation method. Hardware-in-the-loop (HIL) simulation systems are hybrid systems consisting of one or more software system and at least one hardware system which are interconnected by means of a specific interfacing system. For both simulation topologies, the primary part of the electrical system is simulated by means of real-time capable models implemented on a digital real-time simulator (DRTS). The hardware system is represented by selected hardware components of the PV inverter itself. For CHIL simulation, the hardware system is the control board of the inverter and all other peripheral hardware of the PV inverter is modelled in software. For PHIL setups, the physical hardware device serves as the hardware system which is directly interconnected to a power interface (PI). Based on the concept of real-time based HIL setups, the accurate testing of PV inverters is possible, and results are compared to the hardware-only test setup for the purpose of validation. This work includes the explanation of the different test setups and explains different use cases in which CHIL/PHIL setups and hardwareonly tests may be used for the purpose of validated investigation and accurate testing.

description: As the ESA Rosetta mission approached, orbited, and sent a lander to comet 67P/Churyumov-Gerasimenko in 2014, a large campaign of ground-based observations also followed the comet. We constrain the total activity level of the comet by photometry and spectroscopy to place Rosetta results in context and to understand the large-scale structure of the comet's coma pre-perihelion. We performed observations using a number of telescopes, but concentrate on results from the 8m VLT and Gemini South telescopes in Chile. We use R-band imaging to measure the dust coma contribution to the comet's brightness and UV-visible spectroscopy to search for gas emissions, primarily using VLT/FORS. In addition we imaged the comet in near-infrared wavelengths (JHK) in late 2014 with Gemini-S/Flamingos 2. We find that the comet was already active in early 2014 at heliocentric distances beyond 4 au. The evolution of the total activity (measured by dust) followed previous predictions. No gas emissions were detected despite sensitive searches. The comet maintains a similar level of activity from orbit to orbit, and is in that sense predictable, meaning that Rosetta results correspond to typical behaviour for this comet. The gas production (for CN at least) is highly asymmetric with respect to perihelion, as our upper limits are below the measured production rates for similar distances post-perihelion in previous orbits.

description: Besides climate protection, sustainable development needs increasing endeavors regarding biodiversity and nature protection as well as climate and sustainability adaptation in agriculture and concepts for integrated and multifunctional land use, addressing increasing land use competitions. To address these challenges simultaneously, we present the Agri4Power concept as a new “nature-conserving agrivoltaics” concept. It is characterized by a combination of agricultural land use (including energy plants) with sustainable electricity production through bifacial vertical photovoltaic (PV) module systems and nature and species conservation through flower strips. The concept is in line with agricultural production, may stabilize income for farmers and has the potential to contribute to the further expansion of photovoltaics at higher electricity market values. The Agri4Power concept presents socially supported opportunities to make an important contribution to energy sector transition and to improve biodiversity protection and ecosystem services in agricultural areas. Due to its considerable potentials in various applications, the Agri4Power concept may open up new land resources for renewable energy expansion.

description: We often use search engines when seeking information for opinion-forming and decision-making on debated topics. However, searching for resources on debated topics to gain well-rounded knowledge is cognitively demanding, leaving us vulnerable to cognitive biases, such as confirmation bias. This can impede well-informed decision-making, and on a societal level, snowball to compel extremism and polarization. Most existing approaches to support better search apply nudges that directly modify user behavior. Such interventions bear the risk of harming user autonomy. Here, we discuss the shift we envision towards autonomy-preserving interventions that boost users’ metacognitive skills, specifically their intellectual humility (IH)–the ability to recognize the fallibility of one’s beliefs and the limits of one’s knowledge. While simple interventions to boost IH have shown promise, the effect on users’ search behavior has yet to be investigated. We present critical research questions, challenges, and an initial research plan to advance knowledge in this area.

description: The TeV binary system LS I +61$^\circ$ 303 is known for its regular, non-thermal emission pattern which traces the orbital period of the compact object in its 26.5 day orbit around its B0 Ve star companion. The system typically presents elevated TeV emission around apastron passage with flux levels between 5% and 15% of the steady flux from the Crab Nebula (> 300 GeV). In this article, VERITAS observations of LS I +61$^\circ$ 303 taken in late 2014 are presented, during which bright TeV flares around apastron at flux levels peaking above 30% of the Crab Nebula flux were detected. This is the brightest such activity from this source ever seen in the TeV regime. The strong outbursts have rise and fall times of less than a day. The short timescale of the flares, in conjunction with the observation of 10 TeV photons from LS I +61$^\circ$ 303 during the flares, provides constraints on the properties of the accelerator in the source.

Challenges of National Bank Directives on Forex Utilization of Private Commercial Banks
Creators: name: Dereje, Shiferaw
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The aim of the study was to identify the challenges of Private Banks' Forex utilization due to NBE Directives. NBE is the responsible organ to supervise financial institutions like Banks. There are 16 Private Commercial Banks operating in Ethiopia. Private Banks have been playing an important role in the Country's overall development. But some directives issued by NBE have been seen as a challenge for these Banks to foster their progress as they deemed. The study revealed that the directives issued by NBE have a negative impact on Forex utilization of Private Banks and discouraged Banks to achieve their goals in a specified period of time. Though NBE requirements or directives are not the sole reasons, most Bank professionals believe that these directives have an impact on their progress. Regarding the methods of the study, both quantitative and qualitative research methods were applied to identify the real challenges of Private Banks. The study covered six pioneers Private Banks branches found in Addis Ababa as per the date of establishment. A total of 87 IB Managers/Heads and Officers participated in the study. A combination of primary and secondary data had been taken for the study. Some secondary sources like directives and annual reports were used to supplement the study. Semi-structured interview randomly selected participants was carried out. The data analyzed conducted through a mixture of exploratory and descriptive research design. It adapted a survey approach with the use of questionnaires designed to elicit opinions about the real challenges of NBE Directives on Forex utilization of Private Banks from IB Managers/Heads and Officers point of view. To analyze the quantitative data, descriptive statistics was applied. The result of the study showed that some directives issued in connection with FCY have an impact on the overall performance of these Banks. Although some directives have been revised, the impact remains the same as the previous ones. The study identified real factors which challenges the Forex utilization of Private Banks. The findings suggested that some directives should be revised.

description: To understand the potential of Vehicle Integrated Photovoltaics (VIPV) on commercial trucks and vans within Europe, we investigate five use cases: A) parcel delivery van, B) rural delivery truck, C) long haul, D) trailer, E) trailer with battery; we consider the European cities of Stockholm, Freiburg and Seville. For this, we first performed a vehicle geometry analysis in which we determined the potential to integrate photovoltaics on typical vehicle types with a module efficiency of 21%. Based on Global Horizontal Irradiance (GHI) datasets and location dependent conversion efficiencies we perform a yield calculation and estimate the final solar yield. A key finding is that the self-consumption during standby charging is a critical parameter in the feasibility of VIPV systems and needs to be minimized. We compute the corresponding annual solar range and find significant potential in the EU for the different use cases: A) 6637 to 11450 km, B) 3084 to 5272 km, C) 4828 to 8173 km, D) 763 to 1424 km, E) 4791 to 8134 km, depending on the city and assumed standby charging losses. Additionally, we perform a break-even analysis and find that irradiation, electricity prices, and the vehicle charging efficiency, are highly critical factors that impact the profitability of VIPV systems. Today VIPV is already profitable in Freiburg and Seville and can achieve payback times of 3,4 years for (B) and (C) in Seville and in Freiburg of 4,0 years for (B) and (C) in Stockholm within 6,9 (B) and 7,0 (C) years when mass production is achieved.

description: In this paper, we argue that quantum coherence in a bipartite system can be contained either locally or in the correlations between the subsystems. The portion of quantum coherence contained within correlations can be viewed as a kind quantum correlation which we call correlated coherence. We demonstrate that the framework provided by correlated coherence allows us retrieve the same concepts of quantum correlations as defined by the asymmetric and symmetrized versions of quantum discord as well as quantum entanglement, thus providing a unified view of these correlations. We also prove that correlated coherence can be formulated as an entanglement monotone, thus demonstrating that entanglement may be viewed as a specialized form of coherence.

description: We combine electron energy-loss spectroscopy (EELS) and density functional theory (DFT) calculations to study the dispersion and effective mass of excitons in the bulk of WSe$_2$. Our EELS data suggest substantial deviations from the generic quadratic momentum dependence along the $ΓK$-direction. From the DFT-derived Kohn-Sham states we deduce the EELS response without the inclusion of particle-hole attraction to study the possible role of the single-particle band structure on the exciton behavior. Based on this analysis we argue in favor of a strongly momentum dependent particle-hole interaction in WSe$_2$ and other group VI-transition-metal dichalcogenides.

This applies to unpolarized as well as linearly polarized gluons inside unpolarized protons, and to left-right asymmetric distributions of gluons inside transversely polarized protons, the so-called gluon Sivers effect. The inherent process dependence of these distributions can be studied by comparing to similar, but often complementary observables at LHC.

description: Tilt-horizontal coupling in inertial sensors limits the performance of active isolation systems such as those used in gravitational wave detectors. Inertial rotation sensors can be used to subtract the tilt component from the signal produced by horizontal inertial sensors, but such techniques are often limited by the sensor noise of the tilt measurement. A different approach is to mechanically filter the tilt transmitted to the horizontal inertial sensor, as discussed in this article. This technique does not require an auxiliary rotation sensor, and can produce a lower noise measurement. The concept investigated uses a mechanical suspension to isolate the inertial sensor from input tilt. Modeling and simulations show that such a configuration can be used to adequately attenuate the tilt transmitted to the instrument, while maintaining translation sensitivity in the frequency band of interest. The analysis is supported by experimental results showing that this approach is a viable solution to overcome the tilt problem in the field of active inertial isolation.

Soggetti: Abbiamo considerato 71 soggetti obesi (et� compresa tra 20 e 68 anni; BMI>40 kg/m2 or BMI>35 kg/m2 in presenza di complicazioni metaboliche) classificati in tre gruppi secondo l?istologia epatica: controlli (n=12), steatosi semplice(n=27), e steatoepatite non alcolica (NASH; n=32). Abbiamo valutato i punti chiave del signalling insulinico e l?espressione genica delle molecole implicate nel pathway glucoregolatorio e nella DNL insulino dipendenti mediante PCR quantitativa real-time e Western blotting. RIASSUNTO 5 Risultati: I pazienti con steatosi semplice mostrano una ridotta fosforilazione della chinasi AKT1, responsabile della trasduzione del signalling insulinico, con conseguente sostenuta attivit� del fattore di trascrizione FOXO1 che media l?insulino resistenza a livello trascrizionale. Nonostante nessuna variazione significativa dell?espressione di insulin receptor substrate 1 (IRS1), i livelli proteici e di mRNA di IRS2, target di FOXO1, aumentano progressivamente con la severit� della steatosi dai controlli alla NASH. L?espressione di IRS2 � correlata con la severit� della steatosi, l?insulino resistenza e la dislipidemia. Nei pazienti con NASH, l?upregolazione di IRS2 � associata alla preservata attivit� di AKT2, che � il mediatore gli effetti stimolanti di insulina sulla DNL, e all?overespressione del suo target sterol regulatory element binding protein 1c (SREBP1c), che induce DNL a livello trascrizionale. L?overespressione sia di FOXO1 che di SREBP1c convergono sull?upregolazione della glucochinasi, che fornisce substrati alla DNL, nei pazienti con NASH. Conclusioni: La regolazione differenziale di IRS1 e IRS2 e dei loro effettori a valle AKT1 e AKT2 � coerente con l?upregolazione di FOXO1 e potrebbe giustificare lo stato paradossale di insulino resistenza a carico del pathway glucoregolatorio e l?aumentata insulino sensibilit� di quello liporegolatorio tipico della steatosi e della dislipidemia in pazienti obesi con sindrome metabolica.

description: The integration of photovoltaics into the body of vehicles provides many benefits for e-mobility, like inter alia the extension of the driving range, a decreased number of charging cycles per year and the reduction of CO2- emissions of the transport sector. The greatest challenge in integrating photovoltaics in vehicles is the design-related curvature of the modules that the PV modules must follow. The impact of the curvature on the module technology and the energy yield are central research questions that therefore need to be answered. In this study we apply our previously published energy yield model for 3D curved PV modules to simulate the energy yield potential on the roof and hood of different type of cars by considering the module curvature. The curvature of the VIPV module leads to an inhomogeneous irradiance over the module surface. Thus, to an electrical mismatch within the module which can cause high yield losses. We show that the curvature of the roof decreases the yield up to 25 % when using series interconnection of cells. We present an approach to reduce losses that result though the mismatch. We propose the adaptation of the interconnection topology to the curvature by dividing the module into parallel subgroups containing cells with similar azimuth and elevation angles towards the sun. We develop interconnection topologies for roof and hood integrated PV modules based on this approach and simulate the energy yield potential of each design. We show that a reduction of only 3 % - 6 % compared to a horizontal reference can be achieved by using a reasonable low number of subgroups.

description: Active galactic nuclei (AGN) host some of the most energetic phenomena in the Universe. AGN are thought to be powered by accretion of matter onto a rotating disk that surrounds a supermassive black hole. Jet streams can be boosted in energy near the event horizon of the black hole and then flow outward along the rotation axis of the disk. The mechanism that forms such a jet and guides it over scales from a few light-days up to millions of light-years remains uncertain, but magnetic fields are thought to play a critical role. Using the Atacama large mm/submm array (ALMA), we have detected a polarization signal (Faraday rotation) related to the strong magnetic field at the jet base of a distant AGN, PKS1830-211. The amount of Faraday rotation (rotation measure) is proportional to the magnetic field strength along the line of sight times the density of electrons. Although it is impossible to precisely infer the magnetic fields in the region of Faraday rotation, the high rotation measures derived suggest magnetic fields of at least tens of Gauss (and possibly considerably higher) on scales of the order of light days (0.01 pc) from the black hole.

description: Private companies are important to national economies because they contribute significantly to employment and GDP growth of a country. However, the source of finance to help the growth of the private sector in Ethiopia is limited to the country's commercial banks, which lack the capital or capacity to fund the growth needed by the private sector. Private equity can be a complementary source of finance to help grow the private sector in Ethiopia. The general objective of this study is to examine how the phenomenon of Private Equity investment is practiced in Ethiopia and to assess challenges of private equity investment in Ethiopia , mainly from fund manager's perspective.In line with the stated purpose of using a fund manager's perspective as well as limited time and resources, pure asset owners and entrepreneurs were not interviewed. The study used qualitative data, which were gathered through literature study and in-depth interview. The thesis adopted exploratory approach. The study is qualitative and based on in-depth interviews with people active in the Ethiopian PE investing space. Findings are analyzed and discussed based on data gatheredand through a literature study reviewed. The major findings of this study revealed that PE firm in Ethiopia is at early stage but still growing and also identified challenges for both privately owned companies and private equity investors. For privately owned companies, the challenges include loss of ownership stake, loss of management control, and lack of understanding of private equity investment. For private equity investors, the challenges include lack of exit options, risk of capital repatriation, difficulty to register capital, complexity of family-owned business, size of exiting enterprise, lack of financial reporting standard, and regulation restriction and modification. In addition, two major categories of benefits of private equity investment were identified. Finally, the study concluded by providing recommendations that enable Ethiopia to benefit from private equity, which includes exit strategies, easing capital repatriation, improving registration process, supporting improvement of financial reporting, and policy consistency.

description: Van der Waals junctions of two-dimensional materials with an atomically sharp interface open up unprecedented opportunities to design and study functional heterostructures. Semiconducting transition metal dichalcogenides have shown tremendous potential for future applications due to their unique electronic properties and strong light-matter interaction. However, many important optoelectronic applications, such as broadband photodetection, are severely hindered by their limited spectral range and reduced light absorption. Here, we present a p-g-n heterostructure formed by sandwiching graphene with a gapless bandstructure and wide absorption spectrum in an atomically thin p-n junction to overcome these major limitations. We have successfully demonstrated a MoS2-graphene-WSe2 heterostructure for broadband photodetection in the visible to short-wavelength infrared range at room temperature that exhibits competitive device performance, including a specific detectivity of up to 1011 Jones in the near-infrared region. Our results pave the way toward the implementation of atomically thin heterostructures for broadband and sensitive optoelectronic applications.

description: As in Deformed Special Relativity, we showed recently that the Fock coordinate transformation can be derived from a new deformed Poisson brackets. This approach allowed us to establish the corresponding momentum transformation which keeps invariant the four dimensional contraction $p_μ x^μ $. From the resulting deformed algebra, we construct in this paper the corresponding first Casimir. After first quantization, we show by using the Klein-Gordon equation that the spacetime of the Fock transformation is the de Sitter one. As we will see, the invariant length representing the universe radius in the spacetime of Fock's transformation is exactly the radius of the embedded hypersurface representing the de Sitter spacetime.

description: To clarify the magnetic properties of cluster-glass states in Sr1-xLaxRuO3 (0.3 <= x <= 0.5), we report herein the results of muon spin relaxation (muSR) and neutron powder diffraction measurements. The muSR experiments showed that magnetic clusters start developing well above the peak temperature T^* in the ac susceptibility. The volume fraction of the magnetically ordered region increases continuously with decreasing temperature, showing no anomaly at T^*, and reaches nearly 100% at the lowest temperature. The temperature variation of the volume fraction is essentially independent of the La concentration in the x range presently investigated, although the dc magnetization is significantly suppressed with increasing x. Neutron powder diffraction experiments revealed that the ground state for x = 0.3 is a long-range ferromagnetic ordered state. These results indicate that, with decreasing temperature, cluster-glass states in Sr1-xLaxRuO3 gradually develop into long-range ferromagnetic ordered states with decreasing temperature, and that the magnetic ordering process differs strikingly from that expected for a conventional second-order ferromagnetic transition.

description: Vehicle Integrated Photovoltaics seeks, through solar energy, to increase the autonomy of Electric Vehicle from a renewable and clean source. To know the viability of this technology, it is necessary to develop new studies and tools. Considering the important impact that the effect of shading has on the energy production of photovoltaic surfaces, this paper aims to propose strategies to address the study and its application in VIPV technology. Due to the dynamic behaviour of an Electric Vehicle and the variability of usages it may present, it is necessary to define reference scenarios to approach the study. Thanks to this work, it will be possible to know the solar resource on the surface of an Electric Vehicle in three different shading scenarios in order to, in future studies, analyse the increase in the autonomy of an Electric Vehicle over long road distances, to know the solar resource and energy generation of a fleet of vehicles parked around an office building during a working day or to estimate optimal city routes in terms of energy generation.
A Radial Velocity Test for Supermassive Black Hole Binaries as an Explanation for Broad, Double-Peaked Emission Lines in Active Galactic Nuclei

description: One of the proposed explanations for the broad, double-peaked Balmer emission lines observed in the spectra of some active galactic nuclei (AGNs) is that they are associated with sub-parsec supermassive black hole (SMBH) binaries. Here, we test the binary broad-line region hypothesis through several decades of monitoring of the velocity structure of double-peaked H-alpha emission lines in 13 low-redshift, mostly radio-loud AGNs. This is a much larger set of objects compared to an earlier test by Eracleous et al. (1997) and we use much longer time series for the three objects studied in that paper. Although systematic changes in radial velocity can be traced in many of their lines, they are demonstrably not like those of a spectroscopic binary in a circular orbit. Any spectroscopic binary period must therefore be much longer than the span of the monitoring (assuming a circular orbit), which in turn would require black hole masses that exceed by 1-2 orders of magnitude the values obtained for these objects using techniques such as reverberation mapping and stellar velocity dispersion. Moreover, the response of the double-peaked Balmer line profiles to fluctuations of the ionizing continuum and the shape of the Ly-alpha profiles are incompatible with a SMBH binary. The binary broad-line region hypothesis is therefore disfavored. Other processes evidently shape these line profiles and cause the long-term velocity variations of the double peaks.

description: Statistical solutions have recently been introduced as an alternative solution framework for hyperbolic systems of conservation laws. In this work, we derive a novel a posteriori error estimate in the Wasserstein distance between dissipative statistical solutions and numerical approximations obtained from the Runge-Kutta Discontinuous Galerkin method in one spatial dimension, which rely on so-called regularized empirical measures. The error estimator can be split into deterministic parts which correspond to spatio-temporal approximation errors and a stochastic part which reflects the stochastic error. We provide numerical experiments which examine the scaling properties of the residuals and verify their splitting.

description: Health education plays a pivotal role in promoting a culture of well-being and empowerment among individuals. In Brazil, the creation of a health-promoting culture faces various challenges that demand a holistic approach. Rather than being limited to the mere transmission of information, health education should be contextual and encompass a blend of educational and environmental practices. Effective health education integrates communication, education, and active engagement of the students, aiming to restore individual autonomy and empower individuals to make choices conducive to their overall well-being. This shift from conventional education to a more interactive and inclusive approach is crucial for fostering positive health outcomes.

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 1404-1408
description: This work describes a prototype of a neutral color solar window based on LSC technology that was developed by University of Ferrara and Eni and installed on a building in the Eni Donegani research center for renewable energy and the environment in Novara (Italy). The main purpose of these devices is to generate energy from the transparent surfaces of buildings and, at the same time, to obtain both an aesthetically appealing façade and provide a good quality illumination in the rooms of the building. Five of these prototypes with an active area of 0.61m2 were assembled and installed as the windows of a test building at the Eni Donegani site. The optical, colorimetric and electrical performances of the windows were measured both on-site and off-site at the end of the assembly process. The prototypes showed an average transmittance of 42.2% in the standard visible range (400-700nm) and when lit by sunlight behave as a light source with a CRI of 94.4, which is comparable to halogen lamps. The power production was 2.8W when installed on a diffusive background that drops to 1.2W when installed on the test building which has a non diffusive background.

description: An in situ study of the epitaxial growth of SmN thin films on Ga-polar GaN (0001)templates by molecular beam epitaxy is reported. Using X-ray photoelectron spectroscopy we found that Ga segregates at the surface during the first stages of growth. We showed that the problem related to Ga surface segregation can be simply suppressed by growing a few monolayers of AlN before starting the SmN growth. This results in a significant improvement of the crystallinity of SmN thin films assessed by X-ray diffraction.

description: The development of photovoltaic (PV)-powered vehicles is desirable and can be very important for reducing CO2 emissions, increasing electric range and creating new clean energy infrastructures based on PVs. According to our survey, the use of more than 30 % of high-efficiency PVs enables 30 km/day driving without external charging. With this, the majority of family cars could run by sunlight and without the need for additional fuel. Although the Toyota Prius demonstration car has shown 36.6km/day driving at solar irradiance of 6.2kWh/m2 /day, the expected driving distance of PV-powered vehicles is lower than the estimated values due to some losses, such as temperature increase of solar cell modules under sunshine conditions. This paper presents approaches on the development of high-efficiency solar cell modules. In this paper, analytical results for reduction in non-radiative recombination and resistance losses of various solar cell modules are shown. In addition, temperature coefficients of candidate solar cell modules are analyzed in order to develop highly efficient solar cell modules under sunshine conditions. The III-V compound 3-junction solar cell modules are shown to have potential efficiencies of 37% with better temperature coefficient of -0.19 %/ compared to -0.29 %/ for Si back contact solar cell modules and -0.26 %/ for Si heterojunction solar cell modules. It is also shown the 3-junction solar cell modules have potential driving distance of more than 50km/day on a clear day,
