description: Solar cells require effective protection against environmental influences so that they can convert
sunlight into energy for a long time. Backsheets provide long-term protection for solar cells against mechanical and
chemical influences and the effects of the weather at the backside of the solar cells. State of the art at the frontside is
the usage of glass to ensure protection particularly against water vapour. For thin film PV technologies, flexibility is a
major advantage compared to crystalline solar-cells. As a result new frontsheet materials, which are flexible, are in
the focus. But not only flexibility is a very important property, also WVTR (water vapour transmission rate),
transparency, YI (yellowing index) as well as costs have to be kept in mind.
For CIGS photovoltaic devices, barrier materials with WVTR of at least 10-4 g/m2d are necessary to provide lifetime
of more than 20 years. Aim of the presented work is to introduce new transparent barrier frontsheets for PV
applications.

description: Fast progress in introducing electric energy originated from photovoltaic conversion of solar radiation
in Europe as well as in the world, for a long time has presented Poland in an unfavourable light. Despite the fact that
our country entered the European Union, all the time we were deviating from indicators of renewable sources of
energy depicted their participation in general energetic balance. This situation resulted from many reasons but mainly
from the strong influence of coal lobby. The energy industry of Poland in more than 90% is based on coal energy.
However, wide-ranging propaganda, led in frameworks of EU IEE “PVs in Bloom” Project, which approximated PV
issue to local governors and decision makers in Poland. Quantifiable effect of this was activation of the first
photovoltaic farm with power of 1.8 MWp in September last year. It was opened in one borough of Malopolska -
Wierzchoslawice. While opening the investment, there was the Vice- Prime Minister of the Republic of Poland
presented - Waldemar Pawlak, who at the same time was the minister responsible for energy industry. Simulation of
benefits from producing PV energy, convinced the Minister of Economy about the purposefulness of this kind of
investments in Poland. Certainly, at current stage Poland has not introduced economic mechanisms supporting these
investments, that is why, time of paying back of costs eliminated their profitability. Hence, as a suggestion of this
occurrence, the Ministry of Economy compiled programme of improvement in this sector, editing the Act about the
renewable sources of energy, which bill saw the light of day on December 2011. Although the bill predicts
supporting mechanisms via green certificates, not feed-in tariffs (FiT), but this is step forward in a right direction.
This support would be concentrated mainly on dispersed systems - so called micro power stations, for which
coefficient of green certificates would come to 2.5. There are also very significant 15-year guarantees for this systems
of support functioning. It gives us hope that these would be the green light for development of this sector.

description: Single wavelength scan over the whole area of a multi-crystalline silicon solar cell is utilized to map the
internal quantum efficiency through a pixel by pixel measurement of light induced current and reflectance. As the
wavelength is changed, depth profile information on carrier generation and collection probability varies, which is
correlated with overall cell performance. Wavelength dependent response in correlation with electrical characteristics of
the solar cell will be discussed.
PC1D simulation along with spectral response of experimental data is utilized to obtain additional information such as
back surface recombination velocity. Long wavelength spectral response is utilized to demonstrate strong correlation
between back aluminum (Al) paste composition, back surface field, and back surface recombination velocity of minority
carriers; Composition of the backside Al paste plays a key role in controlling this parameter.

Markets

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 4389-4391
description: In the early 2000s, the feed in tariff incentive model was designed to stimulate demand for photovoltaic
electricity for economic and environmental reasons, and to increase regional manufacturing and installation jobs
while furthering social and economic goals. A general view of spatial theory as it applies to manufacturing would
hold that the logical location for manufacturing is near the market. Concerning incentives, the classic assumptions are
that prices reflect the cost of manufacturing and decrease more or less seamlessly until no longer necessary. This
view ignores the PV industry’s history of aggressive pricing, and its basic immaturity, along with the cost of the
incentives to the market. Consumers maximize utility while sellers maximize profits, and the tension between the
two is the vehicle by which markets are controlled and prices are set. In the case of the PV industry, specifically the
module, the end consumer is separated by a middleman, such as an installer or system integrator. This paper will
examine several layers of seller/buyer behavior for electricity, in the context of photovoltaic electricity as both a good
(the system) and a commodity (the electricity) and as a distributed generation source. This paper will explore the
various business models the development of which is necessary as the photovoltaic industry moves rapidly back into
a low incentive environment.

description: Drastic increase in demography and economic activity are anticipated to have negative impacts on the
global environment in many aspects. VLS-PV is expected to be one of the key technologies to solve those issues. IEA
PVPS Task8 group has developed a comprehensive roadmap of such systems. The objective of this study is to
analyze the impact of VLS-PV on those sustainability issues under the IEA Task8 roadmap through modeling
approach. The developed model is composed of five sub-modules, namely Energy Supply module, Water
Consumption module, Food Supply & Demand module, Land-use module, and Greenhouse gas emission module.
Population and GDP are the main drivers of the social changes and specifically IPCC SRES B2 scenario is applied as
assumptions of this study. The analysis indicated that VLS-PV can contribute greatly to global sustainability issues,
but the main contribution comes after 2050. Although the contribution of VLS-PV would be marginal in the next 10
years, actions in the first 10 years would be very important from the sustainability perspective.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1938-1941
description: Manz has developed a novel plasma enhanced chemical vapour deposition (PECVD) system combining
both, high productivity and best coating quality. It is based on a high power plasma source (HPP) in a static process. At
high power densities, plasma properties change as compared to conventional equipment resulting in an improved film
forming mechanism. In the newly developed plasma source, gas conversion factors above 80% could be observed, being
the key parameter for film deposition at high throughputs.
In cooperation with Fraunhofer ISE the applicability of the system has been tested by analysing coating quality and
performance of typical passivation layers on front and back side of standard solar cells. For single layer a-SiNx:H antireflection
coatings, efficiencies equal to state-of-the-art cells could be obtained, 17.0% on multi and 18.6% on mono
crystalline material. With an advanced layer stack a further increase of 0.1% is possible. Also back side passivation
stacks of Al2O3 and SiNx have been produced and minority carrier life times of up to 1.3 ms could be obtained,
corresponding to an effective surface recombination velocity of about 6.0 cm/s at illumination densities below 1 sun.
Extending the redshift-distance relation in Cosmological General Relativity to higher redshifts
Creators: name: Hartnett, John G.
Publisher: name: arXiv
Year: 2007
Subjects: subject: General Physics (physics.gen-ph)

description: The redshift-distance modulus relation, the Hubble Diagram, derived from Cosmological General Relativity has been extended to arbitrarily large redshifts. Numerical methods were employed and a density function was found that results in a valid solution of the field equations at all redshifts. The extension has been compared to 302 type Ia supernova data as well as to 69 Gamma-ray burst data. The latter however do not not truly represent a `standard candle' as the derived distance modulii are not independent of the cosmology used. Nevertheless the analysis shows a good fit can be achieved without the need to assume the existence of dark matter. The Carmelian theory is also shown to describe a universe that is always spatially flat. This results from the underlying assumption of the energy density of a cosmological constant $Ω_Λ = 1$, the result of vacuum energy. The curvature of the universe is described by a \textit{spacevelocity} metric where the energy content of the curvature at any epoch is $Ω_K = Ω_Λ - Ω= 1-Ω$, where $Ω$ is the matter density of the universe. Hence the total density is always $Ω_K + Ω= 1$

based on single junction a-Si:H absorber layer and tandem junction a-Si:H/μc-Si:H absorber layers deposited on
industrial AKT® Gen 5 tool was studied. A series of intentionally contaminated complete solar cells were prepared
by adding oxygen or nitrogen or methane (carbon precursor) during a Plasma-Enhanced Chemical Vapor Deposition

after a specific impurity concentration in hydrogen, called the critical level, has been exceeded. The contaminated
solar cells were also studied by the means of Secondary Ion Mass Spectrometry (SIMS) in order to investigate the
impurity concentration incorporated into the solar cells’ bulk so the impurity concentration in hydrogen could be
matched to the incorporated impurity concentration in bulk.

description: The Swift/XRT data of 179 GRBs (from 050124 to 070129) and the optical afterglow data of 57 pre- and post-Swift GRBs are analyzed, in order to systematically investigate the jet-like breaks in the X-ray and optical afterglow lightcurves. We find that not a single burst can be included in the ``Platinum'' sample, in which the data satisfy all the criteria of a jet break. By releasing one or more requirements to define a jet break, some candidates of various degrees could be identified. In the X-ray band, 42 out of the 103 well-sampled X-ray lightcurves have a decay slope of the post-break segment >1.5 (``Bronze'' sample), and 27 of them also satisfy the closure relations of the forward models (``Silver'' sample). The numbers of the ``Bronze'' and ``Silver'' candidates in the optical lightcurves are 27 and 23, respectively. Thirteen bursts have well-sampled optical and X-ray lightcurves, but only seven cases are consistent with an achromatic break, but even in these cases only one band satisfies the closure relations (``Gold'' sample). The observed break time in the XRT lightcurves is systematically earlier than that in the optical bands. All these raise great concerns in interpreting the jet-like breaks as jet breaks and further inferring GRB energetics from these breaks. By assuming that these breaks are jet breaks, we perform a similar analysis as previous work to calculate the jet opening angle (theta_j) and energetics (E_k) with the ``Silver'' and ``Gold'' jet break candidates. The derived E_K distribution reveals a much larger scatter than the pre-Swift sample. A tentative anti-correlation between theta_j and E_{K,iso} is found for both the pre-Swift and Swift GRBs, indicating that the E_K could still be quasi-universal, if the breaks in discussion are indeed jet breaks(abridge).

description: For materials of varying band gap, we compare energy levels of atomically localized defects calculated within a semilocal and a hybrid density-functional scheme. Since the latter scheme partially relieves the band gap problem, our study describes how calculated defect levels shift when the band gap approaches the experimental value. When suitably aligned, defect levels obtained from total-energy differences correspond closely, showing average shifts of at most 0.2 eV irrespective of band gap. Systematic deviations from ideal alignment increase with the extent of the defect wave function. A guideline for comparing calculated and experimental defect levels is provided.

description: We use the Szekeres inhomogeneous relativistic models in order to fit supernova combined data sets. We show that with a choice of the spatial curvature function that is guided by current observations, the models fit the supernova data almost as well as the LCDM model without requiring a dark energy component. The Szekeres models were originally derived as an exact solution to Einstein's equations with a general metric that has no symmetries and are regarded as good candidates to model the true lumpy universe that we observe. The null geodesics in these models are not radial. The best fit model found is also consistent with the requirement of spatial flatness at CMB scales. The first results presented here seem to encourage further investigations of apparent acceleration using various inhomogeneous models and other constraints from CMB and large structure need to be explored next.

description: This paper presents the design and installation of PV grid connected system for food
kiosk installed at Rajamangala University of Technology Thanyaburi (RMUTT), Pathum Thani province of
Thailand. The monitoring and investigation systems have been continuously done since this system started to
supply to the loads. The main task of this project is to reduce electrical energy consumption of the food kiosk
during daytime. The loads of system are mainly composed of the two fluorescent lamps, two refrigerators, one
microwave oven and all loads are supplied by 220 VAC 50 Hz. Nevertheless, one kilowatt-peak of Photovoltaic
(PV) system has been mounted on the food kiosk’s roof since 2010 to generated DC power and then converted to
AC power via a single phase grid connected inverter. To demonstrate the PV system in an educational area,
particularly in RMUTT, is very important. This is because most students in university come from various
provinces of Thailand including some foreigner students and then whenever they meet the PV system to be applied
in university areas. It is possible that they could take this successful PV system concept to apply in their homes or
around rural areas. As a result, PV dissemination should be widely done throughout Thailand. The monitoring and
system performances of the PV grid connected system have been recorded and have been analyzed. The operating
problems are not found and system components of this PV system are still working well. Electrical energy from
recording has been indicated that PV panels can produce at maximum energy in terms of kilowatt-hours is 5
approximately during noontime. Accordingly, Electrical energy consumption can be practically reduced compared
to full load conditions. In fact, an average energy consumption of full loads can be compensated by energy that to
be produced from PV system by over 50 percent during daytime. The system performance from data logger can be
generally addressed that the PV grid connected system has been suitably operating so far and it can be applied in
other countries, not just in Thailand, particularly in ASEAN community.

description: Evaluating model robustness is critical when developing trustworthy models not only to gain deeper understanding of model behavior, strengths, and weaknesses, but also to develop future models that are generalizable and robust across expected environments a model may encounter in deployment. In this paper we present a framework for measuring model robustness for an important but difficult text classification task - deceptive news detection. We evaluate model robustness to out-of-domain data, modality-specific features, and languages other than English. Our investigation focuses on three type of models: LSTM models trained on multiple datasets(Cross-Domain), several fusion LSTM models trained with images and text and evaluated with three state-of-the-art embeddings, BERT ELMo, and GloVe (Cross-Modality), and character-level CNN models trained on multiple languages (Cross-Language). Our analyses reveal a significant drop in performance when testing neural models on out-of-domain data and non-English languages that may be mitigated using diverse training data. We find that with additional image content as input, ELMo embeddings yield significantly fewer errors compared to BERT orGLoVe. Most importantly, this work not only carefully analyzes deception model robustness but also provides a framework of these analyses that can be applied to new models or extended datasets in the future.

description: We study thermal broadening of the hole spectral function of the two-dimensional t-J model (and its extensions) within the non-crossing approximation with and without the contribution of optical phonons. We find that phonons at finite temperature broaden the lowest energy quasiparticle peak, however, the string excitations survive even for relatively strong electron-phonon coupling. Experimental angle resolved photo-emission spectroscopy(ARPES) results compare well with our calculations at finite temperature when we use strong electron-phonon coupling without any adhoc broadening. In addition, we have studied the role of vertex corrections and we find that their contribution allows us achieve the same overall agreement with the ARPES experimental results but using smaller values for the electron-phonon coupling.

silicon nanowires (Si-NWs) affecting cell device performance, and in particular Si-NWs synthesized by metalassisted
chemical etching of single crystalline silicon (c-Si) wafers. We conducted preliminary temperature- and
power- dependent photoluminescence (PL) studies on n- and p- type nanostructured c-Si. Intense visible PL was
observed which was attributed to carrier quantum confinement and trapping taking place in the resulting etched
structures. The origin of these largely blue-shifted luminescent states is still not completely understood. Our study
corroborates to the suggestion of Si nanocrystals formed by sidewall roughness induced from the etching process and
/or to the presence of porosity within the formed structures.

We evaluate the energy spectrum of a dielectric function by using time-dependent density functional theory. Bulk crystal of BiI$_3$ is an atomic layered semiconductor with the band gap corresponding to the frequency of visible light. The numerical result for the bulk crystal is confirmed to be consistent with the previous experimental results and it does not depend on the number of layers except the monolayer. We reveal the excitons appearing below the resonant peak associated with the inter-band excitation in the monolayer crystal. The unique optical property can be directly observed in the optical absorption or differential reflectance spectrum and distinguish the monolayer crystal from the stacked BiI$_3$.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 2106-2108
description: Plasma enhanced chemical vapor deposition of microcrystalline silicon thin films was studied by
in-situ using Raman spectroscopy. Films were deposited at a growth rate of 0.5 nm/s while their Raman crystallinity
was measured during every 10 nm of film growth. The applicability of in-situ Raman spectroscopy as input of an
active process control was tested by determining the response of film growth to disturbances of the deposition
process. The disturbances were simulated by intentionally varying the composition of the source gas. In-situ Raman
spectroscopy results are compared to ex-situ transmission electron microscopy data and I-V-curves of solar cells. The
response of the layer growth to a disturbance is related to the properties of solar cells including the monitored layers.
Impalement transitions in droplets impacting microstructured superhydrophobic surfaces

description: Liquid droplets impacting a superhydrophobic surface decorated with micro-scale posts often bounce off the surface. However, by decreasing the impact velocity droplets may land on the surface in a fakir state, and by increasing it posts may impale droplets that are then stuck on the surface. We use a two-phase lattice-Boltzmann model to simulate droplet impact on superhydrophobic surfaces, and show that it may result in a fakir state also for reasonable high impact velocities. This happens more easily if the surface is made more hydrophobic or the post height is increased, thereby making the impaled state energetically less favourable.

Spitzer Mid-infrared Study of Sh 2-208: Evolution of Protoplanetary Disks in Low-metallicity Environments

description: This study presents sensitive MIR photometry obtained with the Spitzer/IRAC for a young cluster in Sh 2-208 (S208) located in one of the lowest-metallicity HII regions in the Galaxy, ${\rm [O/H]} = -0.8$ dex. Previous studies suggested that the cluster is $\sim$0.5-Myr old and has a distance of $D = 4$ kpc, which is consistent with the astrometric distance from Gaia EDR3. In $\sim$$3.5 \times 4$-arcmin field, 96 sources were detected in at least one MIR band at $\ge$10$σ$, covering intermediate-mass stars with $\sim$1.0-$M_\odot$ mass detection limit. Total 41 probable cluster members were identified based on the spatial distributions of spectral-energy-distribution slopes derived from the NIR $K_S$ and IRAC bands and extinctions of the sources. The cumulative distribution of the SED slopes for the S208 cluster was not significantly different from those of other clusters in solar-metallicity environments with approximately the same age for intermediate-mass stars, if one also considers non-detected MIR sources identified as S208 cluster members from NIR observations. This suggests that the degree of dust growth/settling does not significantly change with metallicities as different as $\sim$1 dex. The fraction of stars with MIR disk emissions for the cluster members with $\ge$1-$M_\odot$ mass was 64%-93%, which is comparable to the results in solar-metallicity environments. Although this may suggest that dominant disk-dispersal mechanisms for intermediate-mass stars have either no, or very weak, dependence on metallicity, it can be argued alternatively that this may suggest that the disk dispersal process does not work effectively at this young stage.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 4055-4058
description: Interactions between photovoltaic systems and the French low voltage distribution grid have been studied
within a State funded R&D project called ESPRIT in order to have a better knowledge of the situation and make
proposals for a clear improvement of the technical and regulatory framework. The purpose of this project was to
guarantee a proper operation of PV systems satisfying both electricity producers and distribution grid operators. Three
types of actions were realised: analysis of the present regulation, standards and technical guides so as to identify lacks or
inconsistencies, modelling and simulation to evaluate phenomena that are difficult to observe on site (like discharge
currents) or assess the possibilities of new techniques provided by the inverters (islanding detection, active filtering,
voltage regulation…), and monitoring of PV systems that suffer from any operation problem and analysis of the data.
This work resulted in suggestions to improve the regulatory framework, the definition of further research needs related to
the implementation of new functions realised by inverters to resolve problems identified and the proposal of a framework
for the validation of inverter features and performances.

description: A transmitter without channel state information (CSI) wishes to send a delay-limited Gaussian source over a slowly fading channel. The source is coded in superimposed layers, with each layer successively refining the description in the previous one. The receiver decodes the layers that are supported by the channel realization and reconstructs the source up to a distortion. The expected distortion is minimized by optimally allocating the transmit power among the source layers. For two source layers, the allocation is optimal when power is first assigned to the higher layer up to a power ceiling that depends only on the channel fading distribution; all remaining power, if any, is allocated to the lower layer. For convex distortion cost functions with convex constraints, the minimization is formulated as a convex optimization problem. In the limit of a continuum of infinite layers, the minimum expected distortion is given by the solution to a set of linear differential equations in terms of the density of the fading distribution. As the bandwidth ratio b (channel uses per source symbol) tends to zero, the power distribution that minimizes expected distortion converges to the one that maximizes expected capacity. While expected distortion can be improved by acquiring CSI at the transmitter (CSIT) or by increasing diversity from the realization of independent fading paths, at high SNR the performance benefit from diversity exceeds that from CSIT, especially when b is large.

description: SINGULUS developed a new evaporation technology for metals that provides high thickness uniformity while parasitic chamber deposition is significantly reduced. The results enable the design of evaporation tools for mass production of next generation solar cells with high uptime and high throughput. The paper reviews the fundamental problem with conventional evaporation and describes the principal and advantages of our new technology. We present data on layer characteristics like thickness distribution, sheet resistance, growth of the deposited metal layer and temperature impact on the wafer. Furthermore we compare our development with a standard evaporator tool. Finally an outlook on machine concepts for either laboratory applications up to mass production tools is given.

description: Emitter and BSF/FSF formation by ion implantation and annealing is an emerging technology that can
boost solar cell efficiencies in standard cell designs and enable high-efficiency cell concepts. For the standard full Al
BSF cell architecture we have developed Phosphorus implant and oxidation-anneal processes to make emitters and
oxide passivation layers that result in 19+% average cell efficiency on good quality Cz material (156 mm). Our
efforts to develop novel process flows that utilize the directional nature of ion implantation have enabled cell
architectures that can achieve 20+% cell efficiencies with a competitive cost-of-ownership.
