description: Resolved debris disc images can exhibit a range of radial and azimuthal structures, including gaps and rings, which can result from planetary companions shaping the disc by their gravitational influence. Currently there are no tools available to determine the architecture of potential companions from disc observations. Recent work by Rodigas et al. (2014) presents how one can estimate the maximum mass and minimum semi major axis of a hidden planet empirically from the width of the disc in scattered light. In this work, we use the predictions of Rodigas et al. applied to two debris discs HD 202628 and HD 207129. We aim to test if the predicted orbits of the planets can explain the features of their debris disc, such as eccentricity and sharp inner edge. We first run dynamical simulations using the predicted planetary parameters of Rodigas et al., and then numerically search for better parameters. Using a modified N-body code including radiation forces, we perform simulations over a broad range of planet parameters and compare synthetics images from our simulations to the observations. We find that the observational features of HD 202628 can be reproduced with a planet five times smaller than expected, located 30 AU beyond the predicted value, while the best match for HD 207129 is for a planet located 5-10 AU beyond the predicted location with a smaller eccentricity. We conclude that the predictions of Rodigas et al. provide a good starting point but should be complemented by numerical simulations.

description: A method is presented for estimating the energy yield of photovoltaic (PV) modules at arbitrary locations in
large geographical areas. The method applies a mathematical model for the energy performance of PV modules as a function
of in-plane irradiance and module temperature and combines this with solar irradiation estimates from satellite data and
ambient temperature values from ground station measurements. The method is applied to three different PV technologies:
crystalline silicon, CuInSe2 and CdTe based thin-film technology in order to map their performance in fixed installations
across most of Europe and to identify and quantify regional performance factors. The results show that the performance of
PV modules may deviate up to 12% from the performance estimated from nominal power, with a clear dependency on
geographical location (higher performance in colder climates). It is also found that there is a clear technology dependence of
the geographical variation in PV performance.

description: The influence of the Mo back contact (110) texturation on the crystalline properties of CIGSe
layers co-evaporated by the 3-stage process and related cells is investigated. The experimental results show that
the presence of a sputtered ZnO layer on the soda lime glass substrate enhances the Mo (110) texture. Within the
investigated texturation range, neither the CIGSe layers nor the behavior of 16 % level cells appear influenced by
this parameter.

description: Mismatch losses due to non-uniform conditions such as partial shading are the focus of much attention.
New products aimed at reducing those losses in long series strings introduce system complexities while promising
substantial performance gains. A simpler strategy to combat mismatch losses is to reduce the number of modules in
series, and increase the number of modules parallel. This study compares two nearly identical 5kW a-Si arrays to
evaluate both the magnitude of mismatch losses and the performance gains that a parallel configuration can provide
under various non-uniform conditions. It is also the beginning of a long-term evaluation that will ultimately provide
design guidelines and cost-benefit analysis.

description: Grass-dominated ecosystems cover ~40% of Earth's surface with tropical grasses accounting for ~20% of global net primary productivity. C3 (cool/temperate) and C4 (tropical and subtropical) grass distribution is driven primarily by temperature. In this work, we used phytolith assemblages collected from vegetation plots along an elevation and temperature gradient in the Northern Andes (Colombia and Ecuador) to develop a paleothermometer for the region. To accomplish this, we created a transfer function based on the relationship between mean annual temperature (MAT) and the phytolith-based Climatic Index (1-Ic), which is the proportion of C4 grass phytoliths (GSSCP) over the sum of GSSCP. To evaluate how accurately the index reflects C4-C3 grass abundance in vegetation plots, we compared it with semi-quantitative floristic estimates of C4-C3 grass abundance. To further evaluate the 1-Ic index as a proxy for C4-C3 grass abundance, we compared it with corresponding ∂13C values (an independent proxy for C4-C3 vegetation). Results indicate that 1) GSSCP assemblages correctly estimate C4-C3 grass abundance in vegetation plots; 2) the Ic index outperforms the ∂13C record in estimating C4-C3 grass abundance, even in open vegetation types; and 3) our Ic index–based model accurately predicts MAT. This new calibrated proxy will help improve paleotemperature reconstructions in the northern Andes since at least the emergence and spread of C4 grasses in the region during the late Miocene.

description: Tin sulfides are important candidates for making a heterojunction with iron pyrite (FeS2) in order to
manufacture solar cells. This paper summarizes the synthesis of tin (II) sulfide (SnS) and tin (IV) sulfide (SnS2) thin
films. The materials were created from sulfurizing vacuum deposited tin films on soda lime glass. It was observed
that the best SnS and SnS2 films were obtained by single step sulfurization performed at 250°C and 350°C
respectively. The structure and composition of the films were determined by X-ray diffraction (XRD) and Raman
Spectroscopy. Optical studies of SnS and SnS2 yielded a bandgap of 1.61 eV and 2.52 eV respectively.

description: We introduce the Solitary Local Dwarfs Survey (Solo), a wide field photometric study targeting every isolated dwarf galaxy within 3 Mpc of the Milky Way. Solo is based on (u)gi multi-band imaging from CFHT/MegaCam for northern targets, and Magellan/Megacam for southern targets. All galaxies fainter than Mv = -18 situated beyond the nominal virial radius of the Milky Way and M31 (>300 kpc) are included in this volume-limited sample, for a total of 42 targets. In addition to reviewing the survey goals and strategy, we present results for the Sagittarius Dwarf Irregular Galaxy (Sag DIG), one of the most isolated, low mass galaxies, located at the edge of the Local Group. We analyze its resolved stellar populations and their spatial distributions. We provide updated estimates of its central surface brightness and integrated luminosity, and trace its surface brightness profile to a level fainter than 30 mag./sq.arcsec. Sag DIG is well described by a highly elliptical (disk-like) system following a single component Sersic model. However, a low-level distortion is present at the outer edges of the galaxy that, were Sag DIG not so isolated, would likely be attributed to some kind of previous tidal interaction. Further, we find evidence of an extremely low level, extended distribution of stars beyond 5 arcmins (>1.5 kpc) that suggests Sag DIG may be embedded in a very low density stellar halo. We compare the stellar and HI structures of Sag DIG, and discuss results for this galaxy in relation to other isolated, dwarf irregular galaxies in the Local Group.

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1017-1020
description: This paper introduces two photoluminescence-based techniques for imaging the dopant concentration
in silicon wafers. Monitoring the band-to-band photoluminescence intensity is a highly sensitive method for excess
carrier lifetime measurement. Such measurements are unaffected by various experimental artefacts caused by
minority carrier trapping and depletion region modulation at low injection. The first technique is based on measuring
the formation rate of iron-acceptor pairs, monitored by band-to-band photoluminescence in low injection. This
calibration-free method provides accurate acceptor concentration images on p-type wafers, even if compensating
dopants such as phosphorus are present. The second technique is based on photoluminescence images of unpassivated
wafers, where the excess carrier concentration is pinned by a high surface recombination rate. This rapid technique is
applicable to either p- or n-type wafers, creating high resolution images of the net doping density.

description: We study inelastic vibration-assisted charge transfer effects in two-site molecular junctions, focusing on signatures of vibrational anharmonicity on the electrical characteristics and the thermoelectric response of the junction. We consider three types of oscillators: harmonic, anharmonic-Morse allowing bond dissociation, and harmonic-quartic, mimicking a confinement potential. Using a quantum master equation method which is perturbative in the electron-vibration interaction we find that the (inelastic) electrical and thermal conductances can be largely affected by the nature of the vibrational potential. In contrast, the Seebeck coefficient, the thermoelectric figure-of-merit, and the thermoelectric efficiency beyond linear response, conceal this information, showing a rather weak sensitivity to vibrational anharmonicity. Our work illustrates that anharmonic (many-body) effects, consequential to the current-voltage characteristics, are of little effect for the thermoelectric performance.

description: In this paper we present the results of first year activity of a project funded by the local government of
Lombardia (Italy) whose target is the development of a new roll-to-roll method for CIGS deposition on flexible
substrates there the modules are laser structured. This project is an example of collaboration between University and
small-size industries founded by the local government which offer opportunities to new and small entrepreneurs to
enter in the photovoltaic field. The CIGS layer is deposited by sputtering on stainless steel substrate covered by
molybdenum. The module is completed with a CdS buffer layer deposited by chemical bath deposition and ZnO +
ZnO(Al) deposited by sputtering. The sequence of scribing to prepare CIGS thin-film solar cell strips and to
interconnect them monolithically has been developed using only lasers. A new procedure for P2 scribing step has
been proposed.

description: We present a multiple scattering vector radiative transfer model which produces disk integrated, full phase polarized light curves for reflected light from an exoplanetary atmosphere. We validate our model against results from published analytical and computational models and discuss a small number of cases relevant to the existing and possible near-future observations of the exoplanet HD 189733b. HD 189733b is arguably the most well observed exoplanet to date and the only exoplanet to be observed in polarized light, yet it is debated if the planet's atmosphere is cloudy or clear. We model reflected light from clear atmospheres with Rayleigh scattering, and cloudy or hazy atmospheres with Mie and fractal aggregate particles. We show that clear and cloudy atmospheres have large differences in polarized light as compared to simple flux measurements, though existing observations are insufficient to make this distinction. Futhermore, we show that atmospheres that are spatially inhomogeneous, such as being partially covered by clouds or hazes, exhibit larger contrasts in polarized light when compared to clear atmospheres. This effect can potentially be used to identify patchy clouds in exoplanets. Given a set of full phase polarimetric measurements, this model can constrain the geometric albedo, properties of scattering particles in the atmosphere and the longitude of the ascending node of the orbit. The model is used to interpret new polarimetric observations of HD 189733b in a companion paper.

description: centrotherm photovoltaics AG is one of the first turn-key supplier of fabrication lines for the
production of whole Cu(In,Ga)Se2 (CIGS)-based thin-film modules of a size of ~1.5m2. The core-technologies for
CIGS-absorber layer formation were developed in centrotherms research & development centre in Blaubeuren
(Germany) and represent a completely new approach, based on a two-stage concept, consisting of deposition of a
precursor (stacked elemental layer, SEL) followed by a rapid thermal process (RTP) for CIGS formation. The
sequential approach with an SEL has the advantage of an easy scalability to large areas but the disadvantage of CIGSformation
normally taking place far away from thermodynamic equilibrium and being determined to a large extend
by kinetics. Thus, frequently very long annealing times of up to several hours are chosen for CIGS formation, to gain
sufficient process control on this crucial annealing step. Since these long process times contradict with the growing
demand for cheaper photovoltaics, centrotherms CIGS-formation process was designed with a 1min cycle-time. For
these unrivalled short process times, it is crucial to generate a profound knowledge about the underlying solid state
reactions to ensure a complete process control. centrotherm photovoltaics AG, together with GE Sensing &
Inspection Technologies GmbH, has set up an unique laboratory-scale in-situ X-Ray diffraction (XRD) system
allowing for the real-time investigation of phase formation processes with a time resolution of 1s. In this work, first
results from this in-situ XRD are presented, focusing on the crucial stages of initial phase formations during
annealing. It will be shown, that different ways of Se-supply during annealing lead to very different phase formations,
nevertheless the basic properties of the obtained CIGS-layers in the end turn out to be mostly independent of the
chosen RTP-route.

description: Polycrystalline samples of the quarter-doped manganites $R_{0.75}$Ca$_{0.25}$MnO$_3$ ($R$ = Y, Tb, Dy, Ho, and Er) were studied by X-ray diffraction and AC/DC susceptibility measurements. All five samples are orthorhombic and exhibit similar magnetic properties: enhanced ferromagnetism below $T_1$ ($\sim80$ K) and a spin glass (SG) state below $T_{SG}$ ($\sim30$ K). With increasing $R^{3+}$ ionic size, both $T_1$ and $T_{SG}$ generally increase. The single crystal neutron diffraction results on Tb$_{0.75}$Ca$_{0.25}$MnO$_3$ revealed that the SG state is mainly composed of a short-range ordered version of a novel canted (i.e. noncollinear) antiferromagnetic spin state. Furthermore, calculations based on the double exchange model for quarter-doped manganites reveal that this new magnetic phase provides a transition state between the ferromagnetic state and the theoretically predicted spin-orthogonal stripe phase.

description: In the Bridgman growth of p-type CuInSe2 monocrystals from a melt of copper, indium and selenium
in the stoichiometric proportions of 1:1:2 respectively, if elemental sodium is added into the melt in the amount
greater than 0.3 at. %, the resulting ingot becomes n-type. This conversion from p- to n-type material also occurs for
melt compositions corresponding to the formula CuInSe2+x, with x the atomic excess of Se over stoichiometry, but
for an increased amount of added Na in the melt. The results so far indicate that to obtain conversion, 1 to 2 atoms of
Na are needed for every 1 of excess Se. It is speculated that this could arise if the process involved the formation of
the binary Na2Se in the first stage. For x = 0.2 and above, no type change was observed, since for this excess of Se, a
prohibitively large and damaging amount of Na would be needed to create n-type material.

description: Local electronic structure and composition around grain boundaries GB in Cu(In1-xGax)Se2 absorber
layers with Ga substitution ratio x of 0.4 ~ 1.0 prepared by three-stage evaporation have been studied by means of
photo-assisted UHV-Kelvin probe force microscopy KPFM and scanning Auger electron spectroscopy AES. In
KPFM measurements of all of the specimens, work function has exhibited a “dip” at GB. A built-in potential at GBs
was in the range of 150 to 250 meV, which was significant to affect transport properties of CIGS, indicates a
presence of a local lowering of valence band maximum or conduction band minimum. For most of the GBs examined,
an illumination of 685 nm laser resulted in a spatially uniform rise of work function by about 100 meV. There was
little difference between surface photovoltage SPV at GBs and grain-surfaces. This spatially uniform feature of SPV
indicates that the connection of conduction band between grains through GB should be flat. In-situ AES
measurements of cross section of the specimen has revealed a promotion of Cu-depletion at the GBs. The spatial
distributions of work function and SPV indicate that electronic connection between most of crystallites of CIGS
should consist of almost flat conduction band connection and valley structure in valence band one, which would be
beneficial to the promotion of the carrier-separation. The observed compositional fluctuation suggests that the
asymmetric expansion of band gap energy may be attributed to segregation of Cu-depleted phases at the GBs.

description: In this work, we report minority charge carrier lifetime degradation in dark of up to 20 μs at room
temperature in air ambient in P-gettered Cz-Si wafers passivated with PECVD SiNx. We have shown that this effect
is dominated by the bulk and not effected by the surface or the measurement. The degradation is much slower than
the degradation observed during the light induced degradation (LID) process. Furthermore, increase in substrate
temperature slows down the degradation in dark (DID) mechanism to large extend. The substrates show very fast LID
when exposed to light and the light induced defects can be repaired within a few seconds by an annealing at 200°C.
In the degraded states of LID and DID, the characteristic rings of Cz-Si material are visible. It indicates that the DID
mechanism is driven by the B-O complexes in the bulk of the material. In order to observe this effect, which was not
found yet by other groups, we assume that our material has high oxygen concentration, low Fei concentration and
high dislocation density.

description: A theoretical model, which relates the binding energy of a positively charged exciton in a quantum dot with the confinement energy is presented. It is shown that the binding energy, defined as the energy difference between the corresponding charged and neutral complexes confined on the same excitonic shell strongly depends on the shell index. Moreover, it is shown that the ratio of the binding energy for positively charged excitons from the $p$- and $s$-shells of a dot depends mainly on the nearly perfect confinement in the dot, which is due to the "hidden symmetry" of the multi-electron-hole system. We applied the theory to the excitons confined to a single GaAlAs/AlAs quantum dots. The relevant binding energy was determined using the micro-photoluminescence and micro-photoluminescence excitation magneto-spectroscopy. We show that within our theory, the confinement energy determined using the ratio of the binding energy corresponds well to the actual confinement energy of the investigated dot.

description: In this paper, we solved numerically the Quantum Spectral Curve (QSC) equations corresponding to some twist-2 single trace operators with even spin from the $sl(2)$ sector of $AdS_5/CFT_4$ correspondence. We describe all technical details of the numerical method which are necessary to implement it in C++ language. In the $S=2,4,6,8$ cases, our numerical results confirm the analytical results, known in the literature for the first 4 coefficients of the strong coupling expansion for the anomalous dimensions of twist-2 operators. In the case of the Konishi operator, due to the high precision of the numerical data we could give numerical predictions to the values of two further coefficients, as well. The strong coupling behaviour of the coefficients $c_{a,n}$ in the power series representation of the ${\bf P}_{\!a}$-functions is also investigated. Based on our numerical data, in the regime, where the index of the coefficients is much smaller than $λ^{1/4}$, we conjecture that the coefficients have polynomial index dependence at strong coupling. This allows one to propose a strong coupling series representation for the ${\bf P}$-functions being valid far enough from the real short cut. In the paper the qualitative strong coupling behaviour of the ${\bf P}$-functions at the branch points is also discussed.

description: We demonstrate theoretically that photon-photon attraction can be engineered in the continuum of scattering states for pairs of photons propagating in a hollow-core photonic crystal fiber filled with cold atoms. The atoms are regularly spaced in an optical lattice configuration and the photons are resonantly tuned to an internal atomic transition. We show that the hard-core repulsion resulting from saturation of the atomic transitions induces bunching in the photonic component of the collective atom-photon modes (polaritons). Bunching is obtained in a frequency range as large as tens of GHz, and can be controlled by the inter-atomic separation. We provide a fully analytical explanation for this phenomenon by proving that correlations result from a mismatch of the quantization volumes for atomic excitations and photons in the continuum. Even stronger correlations can be observed for in-gap two-polariton bound states. Our theoretical results use parameters relevant for current experiments with Rb atoms excited on the D2-line.

description: Humans use context and scene knowledge to easily localize moving objects in conditions of complex illumination changes, scene clutter and occlusions. In this paper, we present a method to leverage human knowledge in the form of annotated video libraries in a novel search and retrieval based setting to track objects in unseen video sequences. For every video sequence, a document that represents motion information is generated. Documents of the unseen video are queried against the library at multiple scales to find videos with similar motion characteristics. This provides us with coarse localization of objects in the unseen video. We further adapt these retrieved object locations to the new video using an efficient warping scheme. The proposed method is validated on in-the-wild video surveillance datasets where we outperform state-of-the-art appearance-based trackers. We also introduce a new challenging dataset with complex object appearance changes.

description: In general – the PV charge controllers are the only elements of the solar installation determining its
overall energetic efficiency, while the user of the basic energy source i.e. the PV module has no influence on the
quantity of energy portion delivered. That’s why most of controller’s elements, as well as its sole designing ideas –
produce effects dealing not only with the percentage of electric efficiency, but also with parameter accuracy and
repeatibility, with reaction on insolation, reliability variations, dimensions and costs. The topic controller’s designing
idea bases on the choice of a conventional or an MPPT (Max. Power Point Tracking) concept. In the simplest first
one, consisting of the module and the load, usually a battery, these two elements are coupled directly or
quasidirectly, what, according to well known energetic dependencies, can not guarantee a fully efficient PV energy
transfer, except some rare cases. Contrary to the conventional solution – the MPPT one fulfils the required adapting
energy rules, always guaranteeing, that at every insolation, as well as at all load conditions – maximum PV energy is
delivered from the module to the load. Quite obvious are then the benefits of the second concept, though much more
expensive, the efficiency of which may often exceed more, than 20% of that, characterizing the first simple version.
Especially large scale PV installation need a precise balance and consideration of the both solutions’ costs while
choicing. That’s why all the controllers’ designing efforts are still continously aimed towards simplification and cost
reduction methods. Among these efforts many items may be mentioned, such as wide introducing the digital
technique, recently appearing especially efficient and low expensive, the cheap MOS semiconductor switches of
extraordinary low on-resistance, what basically raises the overall efficiency, as well as enhanced technologies of
almost all the regulator’s elements of minor partial importance, but the summary effect of which creates a
considerable growth of resulting efficiency. The authors present in the paper the results of investigations carried out
in recent two years. It was settled that two factors favourably influenced the effectiveness, attractiveness and prices’
reduction especially of the MPPT charge controllers. These are the ingenious designing idea of tracking only one
regulator’s output parameter, eliminating any need of current and voltage multiplying. The second factor bases on the
development of the thick-film technique, enabling easy realization of printed circuits on Al2O3 or AlN substrates of
excellent cooling properties, where not only the circuit paths, but also some discrete resistors and capacitors may be
forme.

description: Predicting strategic goal-oriented multi-agent behavior from observations of play is a ubiquitous task that spans not only computer science, but economics, finance, decision theory, and psychology. Unlike in the single-agent setting, agents cannot myopically maximize their utility. Instead, they must reason about the intentions and goals of the others’ to compete for common resources or to cooperate to achieve a common goal. This complicates matters dramatically, as the natural solution concepts are computationally intractable and do not fail gracefully when even a single player deviates from the equilibrium. Furthermore, the behavior we observe is typically non-smooth and often intentionally deceptive to improve robustness and incorporate aspects of information hiding, e.g., bluffing, misleading or slow-playing. In this thesis, we advocate estimating dual variables, i.e., utilities and regrets, instead of working with the primal behavior directly. We argue these dual variables are easier to estimate, in both theory and practice, than the primal behavior. In particular, these utilities are often relatively smooth, and exhibit nice problem-specific structure. Additionally, in some cases these dual estimates are all that are available— primal procedures are simply inapplicable. We consider behavior prediction in normal-form games and introduce the inverse correlated equilibria (ICE) polytope. This polytope contains the joint-strategies that have no more internal regret than the demonstrated behavior under a potentially unknown utility function. This is similar in spirit, and inspired by, single-agent imitation learning/inverse reinforcement learning methods like Abbeel and Ng [1] and Ziebart et al. [97], which guarantee the expected reward of the prediction matches the demonstrated behavior. Our method, MaxEnt ICE, predicts the maximum entropy joint-strategy from the ICE polytope. This results in a convex objective that we efficiently optimize with simple gradient-based algorithms as well as strong statistical guarantees on the quality of the resulting prediction. This approach provides robust game-theoretic behavior estimates even when observations are scarce. We experiment with our approach on human behavior from psychological studies, as well as real-world firm market entry behavior. To conclude, we tie our estimation approach to the large body of work on game abstraction and equilibrium computation in zero-sum extensive-form games. In particular, a crucial step of equilibrium computation is estimating the utilities induced by a strategy. The chosen abstraction serves as a model class providing computational tractability and improving generalization. Following this insight, we introduce regression counterfactual regret minimization (RCFR), a generalization of CFR, an algorithm for zero-sum equilibrium computation. In essence, RCFR drastically improves flexibility in abstraction design.

description: The efficiency of 16.3% on a 30x30cm2-sized CIS-based thin-film submodule has been achieved by
optimizing its absorber thickness and circuit design. The thicker absorber led to a larger current density (Jsc).
However, it caused a drop in a fill factor (FF) originated from a deterioration of a vertical series resistance (Rs). We
found that the FF dropping could be restricted by an optimization of a sulfurization degree in a crystallization process
of the absorber. From electron back scattering diffraction maps and electron beam induced current analysis, we
observed an enlargement of a grain size and an extension of a space charge region in the absorbers with the higher
sulfurization-degree process. Glow discharge optical emission spectrometry showed that the higher sulfurizationdegree
process enhanced a Ga diffusion. These results clearly showed that the FF improvement came from the
refinement of the absorber quality. A horizontal Rs was also reduced by reviewing the circuit design. Narrowing a cell
width was one of the effective ways to reduce the horizontal Rs, however, it made the Jsc lower. In order to prevent
the Jsc lowering, a possible reduction of dead areas for a monolithically integration was executed. Then the cell width
was optimized by using a self-made device simulator. These results enabled us to accomplish the high-level FF
without the Jsc lowering. The new challenge toward the 17% efficiency is just beginning. We believe that the above
mentioned steady efforts could lead us to the accomplishment of the 17% milestone.

description: The forthcoming diamond wire wafering technology is stirring up increasing interest in the PV community
and, in turn, the chance to recycle the silicon kerf is gaining momentum. Garbo is working to develop a recycling process for
the silicon kerf out of the machining on PV silicon ingots and bricks. One of the main challenges for the reutilization of the
recycled silicon kerf in directional solidification processes derives from the large surface area to volume ratio of the powders
leading to substantial surface oxidation and to SiO-induced carbon contamination of the melt resulting in SiC precipitation.
The goal of this paper is to bring some insight on how different oxygen levels in recycled silicon kerf affect the quality of
ingots and cells. The main conclusion is that an oxygen content of 0,03-0,045% in reclaimed compacted powders - the lowest
tested value – yields comparable solar cells performances of reference production with virgin feedstock although generates
supersaturated carbon concentration in solid silicon and larger SiC inclusion formation.

description: This paper evaluates the results obtained from an experimental photovoltaic
installation on the roof of the building of Electrical and Computer Engineer’s department at
the University of Patras Greece, latitude 380. The influence of solar irradiance, module
temperature, and tilt angle, on the amorphous silicon solar module, describes the real operation
of this type of photovoltaic modules in a region which represents a typical site across Greek
midlands with very high temperatures during summer. The module’s power and efficiency
does not vary significantly with temperature in the case of constant irradiance. Annual
electricity output calculations according to a method earlier developed showed that the
module’s output (under 1007W/m2 and 340 C) has been found about 8.7% lower than the one
specified by the manufacturer under STC. Annual yield calculations led to the conclusion that
the annual electricity yield of south –faced, 380- inclined ASI-F 32/12 a-Si modules is 1.6
times higher compared to this of south –faced, 900- inclined modules (installation onto the
façade of a building) at the same site. The modules’ performance influenced by these
environmental conditions is discussed.

description: We report monolithically integrated flexible Cu(In,Ga)Se2 (CIGS) submodules with energy conversion
efficiencies of over 15%. In the present work, 17-cell-integrated submodules were fabricated on 10×10 cm2 size
flexible substrates using module fabrication process techniques developed for rigid soda-lime glass (SLG) substrates
in our previous work. We have also applied a Na-doping control technique which utilizes sputter-deposited SLG thin
films as the Na source on alkali-free substrates. The highest submodule efficiency demonstrated thus far is 15.9%
(Voc: 11.61 V, Isc: 151.2 mA, FF: 68.4%, aperture area 75.7 cm2).
