description: The desorption of molecular species from ice mantles back into the gas phase in molecular clouds results from a variety of very poorly understood processes. We have investigated three mechanisms; desorption resulting from H_2 formation on grains, direct cosmic ray heating and cosmic ray induced photodesorption. Whilst qualitative differences exist between these processes (essentially deriving from the assumptions concerning the species-selectivity of the desorption and the assumed threshold adsorption energies, E_t) all three processes are found to be potentially very significant in dark cloud conditions. It is therefore important that all three mechanisms should be considered in studies of molecular clouds in which freeze-out and desorption are believed to be important. Employing a chemical model of a typical static molecular core and using likely estimates for the quantum yields of the three processes we find that desorption by H_2 formation probably dominates over the other two mechanisms. However, the physics of the desorption processes and the nature of the dust grains and ice mantles are very poorly constrained. We therefore conclude that the best approach is to set empirical constraints on the desorption, based on observed molecular depletions - rather than try to establish the desorption efficiencies from purely theoretical considerations. Applying this method to one such object (L1689B) yields upper limits to the desorption efficiencies that are consistent with our understanding of these mechanisms.

description: Over the past few years, anti-cancer properties, pharmaceutical and specific health effects of instant green tea attracted consumers' attention. This paper seeks to assess the antioxidant properties of cinnamon instant green tea dried using the spray drying method. Firstly, we prepared a liquid extract (1:10) from green tea and then, the obtained extract was dried using a spray dryer apparatus to produce instant tea. In the next stage, three different percentages of dried cinnamon extract powder were added to the manufactured instant tea in separate containers. In continuous, sensory properties, acidity, pH, total polyphenols content and antioxidant activity of obtained cinnamon instant tea were evaluated. Eventually, the results exhibited that adding cinnamon to instant tea powder significantly increased the amount of polyphenolic compounds and antioxidant activity. Also, the acidity and pH of the tea extract and instant tea powder treatments had a significant difference, statistically (p< 0.05). However, the instant tea treatments containing 3 and 5% of cinnamon had no significant difference. Although when the cinnamon extract was added there was no significant difference, the sensory properties of flavored instant tea improved considerably.

description: Shared solar cooperatives are a very new distributed generation (DG) in Brazil, since it was only regulated in late 2015 and coming into force in 2016. Therefore, there is not much literature about it and the poor knowledge and understanding about this DG model are one of the main barriers for its development. On the other hand, there is a lot of interest to better understand shared solar cooperatives in order to turn it into a reality in the country. This paper presents a web tool for early stages of techno-economic analysis of shared solar cooperatives in order to overcome these barriers, promoting and popularizing this truly democratic energy generation model. The web tool was developed as a complementary tool to the Solar Cooperatives Guide and it was designed to be accessible to any kind of user, from individuals who might have some knowledge and understanding about solar systems and shared solar cooperatives to individuals who know little or even nothing about the subject. The web tool and the PDF of the Solar Cooperative Guide are currently available at America do Sol platform from Instituto IDEAL, which can be accessed through the link: www.americadosol.org/simulador-cooperativas/.

Estimating the expectation values of spin 1/2 observables with finite resources

Year: 2007

description: We examine the problem of estimating the expectation values of two observables when we have a finite number of copies of an unknown qubit state. Specifically we examine whether it is better to measure each of the observables separately on different copies or to perform a joint measurement of the observables on each copy. We find that joint measurements can sometimes provide an advantage over separate measurements, but only if we make estimates of an observable based solely on the results of measurements of that observable. If we instead use both sets of results to estimate each observable then we find that individual measurements will be better. Finally we consider estimating the expectation values of three complementary observables for an unknown qubit.

Homojunction Solar Cells

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 90-95
description: Recently, we demonstrated an efficiency of 25.8% for a both sides contacted silicon solar cell. These cells were realized on n-type Si featuring a boron-doped p+ emitter at the front surface and a full-area tunnel oxide passivating contact (TOPCon) at the rear surface. In this work, we present a detailed electrical and optical loss analysis of this record cell in order to identify options to further improve the cell performance. Using a simulationbased electrical loss analysis, we are able to identify the main loss mechanisms and optimize e.g. the Si material (thickness, resistivity) as well as the front side emitter. Using an optical loss analysis as well as advanced optical simulations we also evaluated the potential of different light trapping schemes in order to increase the short-circuit current density. Altogether, an efficiency potential clearly beyond 26% is predicted, which is currently being investigated experimentally.

description: IRAS19410+2336 is a young massive star forming region with an intense outflow activity. We present here spatially resolved NIR spectroscopy which allows us to verify whether the H2 emission detected in this object originates from thermal emission in shock fronts or from fluorescence excitation by non-ionizing UV photons. Moreover, NIR spectroscopy also offers the possibility of studying the characteristics of the putative driving source(s) of the H2 emission by the detection of photospheric and circumstellar spectral features, and of the environmental conditions (e.g. extinction). We obtained long-slit, intermediate-resolution, NIR spectra of IRAS19410+2336 using LIRIS. As a complement, we also obtained J, H and K_s images with the Las Campanas 2.5m Du Pont Telescope, and archival mid-infrared (MIR) Spitzer images at 3.6, 4.5, 5.8 and 8.0 um. We confirm the shocked nature of the H2 emission, with an excitation temperature of about 2000 K. We have also identified objects with very different properties and evolutionary stages in IRAS19410+2336. The most massive source at millimeter wavelengths, mm1, with a mass of a few tens of solar masses, has a bright NIR (and MIR) counterpart. This suggests that emission is leaking at these wavelengths. The second most massive millimeter source, mm2, is only detected at lambda > 6 um, suggesting that it could be a high-mass protostar still in its main accretion phase. The NIR spectra of some neighboring sources show CO first-overtone bandhead emission which is associated with neutral material located in the inner regions of the circumstellar environment of YSOs.

description: In this work we present data for the outdoor performance monitoring for monofacial and bifacial c-Si heterojunction (HJT) module types in comparison to commercial mono- and bifacial c-Si PERC modules in moderate climate conditions in Russia. For bifacial modules +4% gain is observed for the HJT 72-cell module as compared to the bifacial c-Si PERC module in summer. The HJT gain correlates with daily irradiance and ambient temperature being the highest for hot and sunny days. Further, bifacial gain of the HJT module over monofacial HJT amounts to 10-15% for the summer period. In addition, we determine the initial degradation rate for monofacial HJT modules.

Effect of Light and Heavy Touch on Transtibial Amputees’ Postural Control and Weight-Bearing Asymmetry
Creators: name: Tobaigy, Moaz Hamza A
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The objective of this thesis was to determine the effect of augmented sensory feedback and mechanical support on traumatic unilateral transtibial prosthesis users’ postural stability, neuromuscular control, and weight-bearing asymmetry during quiet stance. Our central hypothesis was that postural instability in traumatic unilateral transtibial prosthesis users is a sensory problem. To test this hypothesis 12 traumatic unilateral transtibial prosthesis users and 12 unimpaired age- and sex-matched adults were recruited, enrolled, and completed the study protocol. Participants postural stability, neuromuscular control, and weight-bearing asymmetry were assessed during quiet stance under three conditions: baseline no touch, light touch, which provides sensory feedback, and heavy touch, which provides mechanical support. Postural stability, neuromuscular control, and weight-bearing asymmetry were characterized by center of pressure mean velocity, total integrated area across select lower limb muscles, and a weight-bearing asymmetry index, respectively. In the first study of this thesis unilateral transtibial prosthesis users were found to have greater medial-lateral but not anterior-postural postural instability than age- and sex-matched adults. Importantly, this medial-lateral instability was only resolved relative to age- and sex-matched adults with mechanical support from heavy touch. In the second study we found that neither light touch (i.e., sensory) nor heavy touch (i.e., mechanical support) shifted traumatic unilateral transtibial prosthesis users’ neuromuscular control of postural stability towards proximal muscles during quiet stance. In contrast, we found that mechanical support from heavy touch significantly reduced the total muscle activity used by traumatic unilateral transtibial prosthesis users during quiet stance. In the third study of this thesis we found that despite improvements in postural stability via heavy touch, there was no accompanying reduction in weight-bearing asymmetry, suggesting that weight-bearing asymmetry is not used as a compensation to maintain stability The results of this thesis suggest that contrary to our central hypothesis postural instability in unilateral transtibial prosthesis users may be attributable to mechanical rather than sensory deficits.

PV Module Design, Manufacture, Performance and Reliability

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 941-945
description: Over the last few years there has been a continuous shift towards photovoltaic (PV) systems operating at higher voltages. This trend is combined with the new generation of transformerless, non-isolated inverters designed to reduce the system complexity and the LCOE, which increases the risk for potential induced degradation (PID). In the PV community, PID is still one of the major technical challenges which is only partially understood or mitigated. To reduce this risk, numerous efforts have been made at the cell and module level. In this study, we are looking for a practical, manufacturable PID solution at the module level without sacrificing power output. For this purpose, we tested a multilayer (EVA and ionomer) encapsulant against the traditional monolithic encapsulant configurations and proved to have a superior resistance to PID.

description: To aid the design and parameterization of risk models used in insurance solutions for the PV industry, we introduced an innovative combination of repeated laboratory measurements and ongoing test field monitoring. This approach aims at the relationship between the real life experience and the STC based performance warranties. Each four samples of ten different module brands and types have been exposed for five years now. In this contribution, we compare the results of indoor module characterization to module parameters derived from outdoor operation, where IV curves are acquired in regular intervals. Dependent on the time scale, this comparison needs different approaches. When looking at the major influences on a PV module’s long term yield, a clear ranking is visible after 5 years of exposition. Deviations from rated values as given in the data sheet have the biggest influence on long-term yield, followed by initial degradation. Differences in cell and module technology are next in the ranking: low light behavior, angular response and spectral response may help some products to perform better than others. Finally, long term degradation may cause different life time yields, as this (typically small) effect will increase differences in module characteristics with time. In this experiment, degradation rates between 0% and 1% per year have been deduced.

The resulting set of recurrence relations and difference equations is solved. The Riemann curvature tensor is derived by antisymmetrization. All results are presented as finite power series in the inverse AdS radius and are unique. The fourth order, which is complete for fields up to spin five, is calculated explicitly. Higher orders can be obtained with the same method.

description: The use of electrically conductive adhesives (ECAs) and ribbons is a cost-efficient solution for the interconnection of silicon heterojunction (SHJ) solar cells already implemented in fully automated stringing equipment. A better understanding of the materials, the interconnection process and the reliability of the modules is still required. In this paper we present results of this interconnection approach focusing on material level, string production and performance analysis in outdoor operation. Firstly, the curing of ECAs is investigated. Furthermore, the volume and contact resistivity initially and after aging is characterized. ECAs in combination with Ag-coated and bare Cu ribbons are processed on an industrial glue stringer TT1600ECA from teamtechnik GmbH to manufacture SHJ solar cell strings. The uniformity of the cured bond line thickness is analyzed with optical microscopy. The bond line thickness is 32 to 38 µm on the sunny side. The peel force is characterized and the strings are further encapsulated in modules to test reliability and outdoor performance. The peel force ranges from 0.5 N mm−1 to 1.0 N mm−1 for certain ECAs. Adequate material combinations for PV modules showed degradation lower than 5% even in extended thermal cycle and damp heat testing. The outdoor test of SHJ modules over one year showed a 2% to 3.5% higher specific energy yield compared to a PERC reference module due to the absence of p-type related light induced degradation and a lower temperature coefficient of SHJ cells. With this work we contribute to the industrialization of ECA technology for SHJ cells by addressing relevant aspects of mass production.

In particular, new light is shed on the proposed interpretation of chemical breakup temperatures as a manifestation of the limiting temperatures predicted by the Hartree-Fock model. The obtained results are discussed within the general context of temperature measurements in multifragmentation reactions.

description: The calculation, preparation and investigation of the nanocomposite of Al2O3 –SiO2 antireflection coating for silicon solar cells with the predicted value of integrated coefficient of reflection (RS) which is not exceeding 10% is presented. By the simulation it was shown, that at concentration of Al2O3 = 52 – 84% and SiO2 = 16 – 48% with the thickness of 53 – 97 nm, the value of RS ≤ 10% and the minimum Rs values will be at the content of composite Al2O3 = 73 – 77% and SiO2 = 27 - 23% with thickness of 69 – 75 nm. The experiment showed that for layers of Al2O3: SiO2 = 75: 25 with a thickness of 72 nm the value of RS is 3,53%, that approximately is twice lower than the RS for the Si3N4 coating.

description: Thin-Film (TF) modules are diverse in their technologies, module designs and module types. We estimate a current cumulated installed TF capacity of 18 to 26 GW (4-5% of ca. 500 GW total PV installations installed worldwide as of 2018). Quality assurance at the system level becomes more and more important since the plant operators, maintenance teams and experts are in need of practical procedures to access the precise value of the actual module power in order to assure the predicted energy yields of their or their clients’ installations. Evaluating the power of the PV module using stabilization procedures is still the most relevant approach necessary to raise a claim in a warranty dispute because it is the only measure at the module level for when the product warranty has expired. A review of the applicable standards (IEC 61215:2016) and manufacturer prescribed stabilization procedures is presented. In August 2018 a long time field installation was set up in Berlin, Germany, and first results have been gained to investigate the topic. It consists of four complete thin film module strings connected to inverters to simulate realistic operational conditions. The latest products from the manufacturers First Solar (FS4), Avancis and Solar Frontier were installed. First, modules from each type were treated to stabilization procedures in accordance with the applicable standard and manufacturer instructions to determine their initial power. After initial operation the modules were dismantled in November 2018 and a transport (four weeks dark-storage) was simulated. Afterwards the modules were stabilized again and re-installed outdoors. The experiment will last for at least 2 years. The results enable a discussion about the differences between the procedures especially to shed light on the somewhat controversial application by testing laboratories of the manufacturer procedures versus those prescribed in international standards.
Generation of atom-atom correlations inside and outside the mutual light cone

description: We analyze whether a pair of neutral two level atoms can become entangled in a finite time while they remain causally disconnected. The interaction with the e. m. field is treated perturbatively in the electric dipole approximation. We start from an initial vacuum state and obtain the final atomic correlations for the cases where n = 0, 1, or 2 photons are produced in a time t, and also when the final field state is unknown. Our results show that correlations are sizable inside and outside the mutual light cone for n= 1 and 2, and also that quantum correlations become classical by tracing over the field state. For n = 0 we obtain entanglement generation by photon propagation between the atoms, the correlations come from the indistinguishability of the source for n = 1, and may give rise to entanglement swapping for n = 2.

description: New HI images from the VLA Galactic Plane Survey show prominent absorption features associated with the supernovae remnant G23.3-0.3 (SNR W41). We highlight the HI absorption spectra and the $^{13}$CO emission spectra of eight small regions on the face of W41, including four HII regions, three non-thermal emission regions and one unclassified region. The maximum velocity of absorption for W41 is 78$\pm$2 km/s and the CO cloud at radial velocity 95$\pm$5 km/s is behind W41. Because an extended TeV source, a diffuse X-ray enhancement and a large molecular cloud at radial velocity 77$\pm$5 km/s are also projected at the center of W41, these yield the kinematic distance of 3.9 to 4.5 kpc for W41. For HII regions, our analyses reveal that both G23.42-0.21 and G23.07+0.25 are at the far kinematic distances ($\sim$9.9 kpc and $\sim$ 10.6 kpc respectively) of their recombination-line velocities (103$\pm$0.5 km/s and 89.6$\pm$2.1 km/s respectively), G23.07-0.37 is at the near kinematic distance (4.4$\pm$0.3 kpc) of its recombination-line velocity (82.7$\pm$2.0 km/s), and G23.27-0.27 is probably at the near kinematic distance (4.1$\pm$0.3 kpc) of its recombination-line velocity (76.1$\pm$0.6 km/s).

description: One of the most crucial aspects to improve further efficiency of CdS/CdTe photovoltaic devices is to minimize the interdiffusion at the interface by using an intrinsic layer. In this paper the influence of an i-CdO layer deposited between the CdS window and the CdTe absorber was studied. The incorporation of this layer led to an enhancement of both short circuit current density and open circuit voltage by 5% and 25%, respectively, without appreciable changes of other parameters of solar cells. After the analysis of the cell parameters extracted from the currentvoltage and capacitance-voltage characteristics, possible origins of this effect was found.

description: Abstract In the present work, occurrence of lightning activity over different ecological zones of Nepal has been studied. It has been observed that Lower Tropical zone receives lightning strikes with largest value of density of strikes whereas the Trans-Himalayan zone receives lightning strikes with least value of density of strikes. The density of lightning strikes over the Lower Tropical zone is 19.87 × 10-2 / km2 per year whereas, that over the Trans-Himalayan is 2.00 × 10-2/ km2 per year. Other three zones whose values were observed to be in the higher side were Upper Tropical, Sub-tropical and Water Body with annual densities of lightning strikes of 14.46 × 10-2 / km2, 12.05 × 10-2 / km2 and 12.00 × 10-2 / km2 respectively. During a year, 2.56 × 10-2 / km2 and 2.17 × 10-2 / km2 are densities of lightning strikes for Alpine and Nival Zones respectively which are close to the lowest value of Trans-Himalayan zone. Remaining two zones, Sub-alpine and Temperate, respectively experienced lightning strikes with densities 6.05 × 10-2 / km2 and 8.83 × 10-2 / km2 per year.

description: Grid-tied PV systems with battery storage have become a common view in many countries, not only for small residential PV systems, but also for commercial and utility scale installations. The battery storage in a PV system allows to displace the usage of the solar generated power to times where consumption or injection is needed or possible. The correct sizing of the PV and storage capacity for these systems is challenging, and depend on climatic factors, geographical location and power dispatch strategy. An accurate simulation of the system over one full year allows to make good design choices and check them under varying conditions. PVsyst is a simulation software that allows to model PV systems, from small residential size up to large utilities. Since end of 2018, the PVsyst software has implemented the possibility to model Grid-tied PV systems with battery storage. Three different dispatch strategies have been foreseen, namely peak shaving, maximizing self-consumption and weak grid support. After briefly discussing the approaches used for modeling these systems, simulation results are presented for all three strategies at different operating conditions. It is shown how the sizing of the PV array and the battery impact on the system performance. General conclusions are presented, as well as individual aspects that need special care, to achieve an optimal battery and PV sizing.

description: View-factor and ray-tracing are the most commonly used methods to estimate the irradiance incident on the rear side of modules in bifacial PV systems. The view-factor method is used in well-known commercial software, such as PVsyst and SAM. On the other hand, the ray-tracing method is not commercialized yet and is rather complicated and time consuming to use. However, it is more accurate and suitable for complicated geometries. Despite the mentioned advantages and disadvantages in both models, a practical comparison of bifacial PV yield predictions using both methods on a system level is not available in the literature to the best knowledge of the authors. This paper determines the accuracy of the view factor method with respect to ray-tracing. The rear-side irradiance is significantly lower in view factor method and mean bias error (MBE) is up to 19.7 % lower than in ray-tracing method.

description: Many 3rd party PV performance degradation studies only report changes of PMAX (usually corrected to STC) with time. The type of degradation (e.g. RSHUNT, RSERIES) can cause differences in “PMAX drop vs. instantaneous weather conditions” and also “Energy Yield changes vs. site”. A new approach is given showing how to identify degradation causes and quantify rates vs. time under different weather conditions (outdoor irradiance and module temperature or as defined in IEC 61853-3 e.g. STC, NOCT or LIC). This enables a better insight for any deviations from performance predictions (from simulation programs or machine learning methods) to help for asset monitoring and control.

description: Nowadays, to response to the demand of a high rate renewable energy penetration in the electricity grids, the installation of many new large-scale photovoltaic systems up to more than 100 MW is unavoidable. Energy generation using solar energy, especially the installation of large-scale solar systems, requires very large areas. As the cost of the land is expensive and the authorities wish to avoid taking away large farmlands for ground-mount photovoltaic systems, the trend is to explore new potential, ecological and effective alternative solutions. Our solution is the linear solar power systems, which is the solar power plant installed along a very long space, terrain up to many kilometers such as highways, bike lanes or even river banks. The possibilities and opportunities of these new kinds of large-scale PV plants are infinite. The purpose of the present work is to present a detailed model for large-scale PV system of which the accuracy is verified. Then we simulate and compare side by side the performance of a linear structure of a 5MWp PV power plant with a classical structure PV power plant of same size. It helps identifying the different technical requirements of this new type of PV power plant architecture and promote the study of an optimal electrical structure of the large-scale linear PV system in the future.

description: The increasing market of vehicle integrated photovoltaic (VIPV) generates a demand for adapted module designs to optimize the energy yield with regards to application related challenges as partial shading. Starting from a 36 full-cell reference module, which can be currently found in caravans, two half-cell and one third-cell design are proposed, fabricated and evaluated with regards to a better partial shading tolerance. The designs are simulated in LTSpice with a two-diode model and measured in a flasher for validation with a shaded area from 0 – 100 %. Furthermore a 30 days outdoor yield evaluation was done in July 2019 with a shading obstacle in front of each module. All three partial cell designs show a better performance under partial shading conditions than the reference. However, under realistic outdoor conditions the benefit is only high, when the direct light component throughout the day is high. The energy yield gain of the adapted designs over the reference is in the range of 10.3 % to 13.7 %, which corresponds to an absolute additional energy of 45 – 110 Wh/day.
Long Tail of Quantum Decay from Scattering Data

description: Whereas the short time behaviour of an unstable quantum mechanical system is well understood from its theoretical as well as experimental side, the long time tail of the very same systems has neither been measured experimentally nor is there a theoretical agreement on how to handle it. We suggest a possible way out of this unsatisfactory state of art. Theoretically we suggest that the correct spectral function entering the Fock-Krylov method to calculate the survival amplitude is proportional to the density of states of a resonance. The latter is essentially the energy derivative of a phase shift. As a bonus, we can connect the survival probability to scattering data via the phase shift. The method then not only establishes the spectral function, but is per se a semi-empirical method to extract the large time behaviour from scattering data.

description: Future photovoltaic factories with Industry 4.0 concepts will have the potential to optimize production quality and costs with improved digitalization, automation and self-learning capabilities. The digitalization of a solar research facility and the concept of a flexible factory is presented, which aims at production of different cell technologies in a single production line. The components to transform to a connected lab that serves as a flexible factory test-bed include: (i) A prototype software to automate the scheduling of processes & booking of equipment (ii) Underlying architecture to actualize a connected lab: communication with process and measurement equipment, data management, equipping production environment with relevant sensors, interaction with web/mobile interfaces. To highlight the problems and advantages of having a connected factory we present the results of a feasibility study of carrier wafer tracking through a production facility without ‘connected’ features.
Theoretical rate of dissociative recombination of HCO$^{+}$ and DCO$^{+}$ ions

description: The article presents an improved theoretical description of dissociative recombination of HCO$^+$ and DCO$^+$ ions with a low energy electron. In the previous theoretical study (Phys. Rev. A {\bf 74}, 032707) on HCO$^+$, the vibrational motion along the CO coordinate was neglected. Here, all vibrational degrees of freedom, including the CO stretch coordinate, are taken into account. The theoretical dissociative recombination cross-section obtained is similar to the previous theoretical result at low collision energies ($$0.1 eV) energies. Therefore, the present study suggests that motion along the CO coordinate does not play a significant role in the process at low collision energies. The theoretical cross-section is still approximately 2-3 times lower than the data from a recent merged-beam experiment.
