description: Electroluminescence investigations on Cu(In,Ga)Se2 mini-modules under different bias conditions reveal
the influence of shunts on the performance of the individual cells and of the entire module. Our analysis assumes
the electroluminescence intensity at each surface position of the module to depend on the actual junction voltage
at this specific location. Therefore, the analysis of the electroluminescence intensity retrieves the current/voltage
characteristics of all individual cells of the module. With these results, we calculate the mean voltage over all cells of
the module and the corresponding standard deviations to classify module performances.

description: The use of visual information for the navigation of unmanned ground vehicles in a cross-country environment recently received great attention. However, until now, the use of textural information has been somewhat less effective than color or laser range information. This manuscript reviews the recent achievements in cross-country scene segmentation and addresses their shortcomings. It then describes a problem related to classification of high dimensional texture features. Finally, it compares three machine learning algorithms aimed at resolving this problem. The experimental results for each machine learning algorithm with the discussion of comparisons are given at the end of the manuscript.

description: This work reports on new hydrogenated amorphous Silicon (a-Si:H) absorber layers and their application in a-
Si:H single junction and Micromorph® tandem modules. An improved material quality with slightly reduced band gap energy
was achieved by a combination of reduced process pressure and RF power density in the a-Si:H PECVD process. The new a-
Si:H absorber layers deliver higher current density and show a reduced light induced degradation. A record initial power of
137.2 W has been achieved for a-Si:H single junction 1.4 m2 module corresponding to a stabilized power above 110 W.
Micromorph modules that include the new high quality a-Si:H absorber in the top cell show a significantly reduced light
induced degradation and correspondingly higher stabilized power with respect to that of Micromorph modules comprising a
standard a-Si:H absorber. Using the high quality a-Si:H absorber layer as well as improved processes for bottom cell, light
trapping, and laser patterning a Micromorph module with the record power of 163 W has been achieved. This record module
power together with the reduced light induced degradation show the ability of Oerlikon Solar to produce large area
Micromorph modules with stabilized total area efficiency above 10%.

MESO-SCALE MODELING OF GRADIENT MICRO-STRUCTURE IN SAND: EFFECT OF SIZE AND DISTRIBUTION OF POROSITY

Void size and distribution

description: Strain concentration at some material points that seem arbitrary- usually called strain localization- is a very common phenomenon in granular media which affects the overall behavior of the material under different scenarios including laboratory tests, failure of natural and man-made slopes, and response of foundations to loading. Classical mathematical models and constitutive equations were mainly based on the elastic behavior of the material and including the post-yielding material behavior and through the plastic region advanced afterwards. More complicated constitutive equations are proposed in recent decades, however, a great portion of them is specified for the behavior of metals. The main objective of this study was to investigate how the distribution of voids and the range of their size in a sand specimen could alter the behavior of the soil as a continuum medium, considering the strain localization behavior (or formation of shear bands) of granular materials in an elastoplastic regime. A gradient plasticity model along with finite element method (FEM) analysis were the main components of this research to model the strain localization in coarse, poorly-graded Ottawa sand. The gradient plasticity model was implemented into ABAQUS using a user-defined code (UMAT) to simulate the effects of various distributions of porosity as pores with different sizes in the behavior of sand under different confining pressures. Different specimens were defined in ABAQUS by keeping the porosity constant but, changing the size and numbers of the holes for different configurations.
description: To validate the results, existing laboratory experiments data of a biaxial test on a coarse, poorly-graded Ottawa sand, along with previous numerical modeling results were used. The parameters, experiment conditions, and soil properties of the current study were based on the actual biaxial test referred to in the next chapters. The results of this study showed good agreements with experimental studies and theoretical expectations. By increasing the number of voids, which conveys the reduction of their size in order to keep the porosity constant, the specimens showed a broader hardening behavior and less distinct formation of shear bands. Instead of shear bands, slip lines were more observable in these specimens which indicated the diffusion of strain at more points compared to its concentration. A similar trend was detectable by increasing the confining pressure.

description: We have investigated the influence of B2H6 addition on the plasma parameters and on the surfacereaction
process during film growth for the optimization of p-type microcrystalline silicon (μc-Si:H) layer in thin film
Si solar cells. We have confirmed from the results of optical emission spectroscopy that the introduction of B2H6
molecules gives rise to an increase of electron temperature in the plasma. Furthermore, sticking coefficient of SiH3
radical to the film-growing surface shows drastic increase in the doping-ratio ([B2H6]/ [SiH4+B2H6]) range above 10-3,
which is explained by dangling-bond-defects production on the film-growing surface through the catalytic H-removal
reaction with BHx chemical species. Quite the same trend had been observed in the case of p-type (boron-doped)
amorphous silicon (a-Si:H) growth, where most of hydrogen atoms do not reach the film-growing surface. This fact
implies that a lot of hydrogen atoms supplied from the plasma under μc-Si:H-growth condition cannot cover surfacedangling
bonds produced by H-removal reaction with BHx.

description: The reliability and long term stability plays an important role for the assessment of a solar cell technology.
Endurance tests of CIGS based solar cells indicate that a redistribution of charges in the heterojunction is the responsible
mechanism for the observed parameter drifts of open circuit voltage, fill factor and reverse characteristics. Time constants of
the observed parameter drifts were determined and assessed with respect to the “lifetime” of the modules. A weak
illumination during the endurance testing is sufficient for the optimization of the device stability. A positive bias which can
be either applied externally to the device or generated as open circuit voltage during illumination appears to be crucial for
counterbalancing the investigated parameter drifts. This study reveals that conditions which are similar to field conditions
optimize the device reliability which is a distinct advantage of the investigated CIGS technology.

description: Cannabis is one of the most commonly used recreational drugs during pregnancy. Despite its increasing popularity, research on the risks of prenatal cannabis exposure has remained limited. This dissertation details my efforts to profile the impact of prenatal cannabis exposure on emotional reactivity, cannabis-seeking behavior, and parvalbumin interneuron expression in offspring. I utilized an innovative model to allow female rats to self-administer tetrahydrocannabinol (THC)-rich cannabis (70% THC; 150 mg/mL) or vehicle vapor in a response-contingent manner. A third group of dams did not self-administer vapor during pregnancy. I used age-appropriate tests to examine emotional reactivity in offspring. Cannabis-seeking behavior was investigated in a separate cohort of offspring using a 22-day paradigm where rats self-administered either cannabis or vehicle vapor under increasing schedules of reinforcement. A final group of offspring underwent immunohistochemical analysis of parvalbumin interneurons in the medial prefrontal cortex. I found that dams assigned to the cannabis group earned more vapor deliveries and showed greater preference for the vapor-paired, “active,” operandum than vehicle dams. On postnatal day (P) 6, cannabis-exposed offspring made more total calls in the isolation-induced ultrasonic vocalization task of emotional reactivity. This effect on emotional reactivity was age-dependent, as it did not reappear on P10 or P13. In adulthood, there were no differences between prenatal treatment groups in the elevated plus maze and novelty suppressed feeding tasks of anxiety-like behavior. Adult cannabis-exposed offspring also displayed sex-dependent effects on cannabis-seeking behavior. Specifically, male cannabis-exposed rats earned fewer vapor deliveries and made fewer nosepokes to the active nosepoke regardless of their assigned vapor. Female cannabis-exposed rats generally showed similar cannabis-seeking behavior to their controls. Finally, no differences in parvalbumin interneuron number or distribution were detected. My dissertation indicates that prenatal cannabis exposure causes age- and sex-dependent effects on emotional reactivity and cannabis-seeking behavior, respectively. It also introduces a novel self-administration model that can be used to provide valuable information to parents, caregivers, and healthcare professionals about the risks associated with prenatal cannabis exposure.

description: An overview is given on the present status of the comCIGS project funded by the German BMU
(Bundesministerium für Umwelt, Naturschutz und Reaktorsicherheit). Five partners are heading this effort which
represents a framework of virtual and experimental Labs: IBM Germany, Schott AG, Helmholtz Zentrum Berlin,
Universities of Mainz and Jena. All the partners have capabilities for computational Materials Science, whereas the
HZ Berlin and University of Jena have pilot lines for CIGS processes. Schott AG mainly concentrates on
optimization and production of specialty glass substrates for CIGS manufacturing. Aim of the project is an
improvement of the overall efficiency of CIGS solar cells by replacing the presently used CdS buffer layer,
optimizing CIGS layer process and using a specially designed glass substrate. As first results a number of >200
ternary alloys (Heusler phases) were identified by numerical simulation that could replace CdS based on the lattice
structure and band gap. The improvement of the CIGS process itself seems to be mainly driven by the combination of
a specialty glass substrate with defined TG, CTE and Na-content, together with a CIGS layer process that produces a
homogeneous layer at elevated process temperatures > 600°C. Solar cell efficiencies of =19.2% could be obtained
using process parameters that are applicable to a manufacturing environment.

It is located in Sierra de San Pedro Martir (SPM) a few kilometers away from Observatorio Astronómico Nacional. The study is based on data collected by the ATMOSCOPE, a multi-sensor instrument measuring the weather and sky conditions, which was commissioned and built by the CTA Consortium. Additionally, we compare the weather conditions of the optical observatory at SPM to the Vallecitos regarding temperature, humidity, and wind distributions. It appears that the excellent conditions at the optical observatory benefit from the presence of microclimate established in the Vallecitos.

A combination of poor weather in several major producing areas, the unprecedented turning of the Soviet Union to world markets to meet its shortfalls, the freeing and rapid fluctuations of exchange rates, and the effects of the energy crisis have driven food prices to new heights. These developments have again raised many questions concerning the world's ability to produce and distribute enough food at reasonable prices to meet the increasing demands of growing populations and rising affluence.

performance indicators such as yield, module power and throughput have been continuously improved. The current
run rate is 2.5 MW/a, yield levels are at 80 % and average module power is at 60 W. The installation of a new and
fully automated production line is almost finished. The line will have capacity of 35 MW/a in the beginning and can
be extended to a full capacity of 75 MW/a on the existing infrastructure platform. The new line will begin producing
by the end of 2009. CuInS2 based modules show excellent stability in accelerated life time tests. Sulfurcell has
developed internal qualification standards which exceed the IEC 61646 requirements. The long term stability of the
CuInS2 module design has been verified by yield data of various test fields at several locations.

description: Controlling anisotropy in nanostructures is a challenging but rewarding task since confinement in one or more dimensions influences the physical and chemical properties of the items decisively. In particular, semiconducting nanostructures can be tailored to gain optimized properties to work as transistors or absorber material in solar cells. We demonstrate that the shape of colloidal lead sulfide nanostructures can be tuned from spheres to stripes to sheets by means of the precursor concentrations, the concentration of a chloroalkane co-ligand and the synthesis temperature. All final structures still possess at least one dimension in confinement. Electrical transport measurements complement the findings.

description: We report local probe ($μ$SR) measurements on the recently discovered tetragonal FeS superconductor which has been predicted to be electronically very similar to superconducting FeSe. Most remarkably, we find that low moment ($10^{-2}-10^{-3}μ_\mathrm{B})$ disordered magnetism with a transition temperature of $T_\mathrm{N}\approx 20$ K microscopically coexists with bulk superconductivity below $T_\mathrm{c}=4.3(1)$ K. From transverse field $μ$SR we obtain an in-plane penetration depth $λ_\mathrm{ab}(0)=223(2)$ nm for FeS. The temperature dependence of the corresponding superfluid density $λ_\mathrm{ab}^{-2}(T)$ indicates a fully gapped superconducting state and is consistent with a two gap s-wave model. Additionally, we find that the superconducting $T_\mathrm{c}$ of FeS continuously decreases for hydrostatic pressures up to 2.2 GPa.

description: Front contact electrodes for thin film silicon (TF Si) solar cells have to combine properties of transparency,
light scattering capacity and low resistivity. In this work, deposition of bilayers LPCVD ZnO is presented. Those bilayers
consist in the combination of a highly doped plus a non-intentionally doped (nid) part, deposited in one growth step. The
sheet resistance of the stack is found lower than the equivalent sheet resistance of the two independent layers. The
bilayers are characterized by a total low electron density and low free carrier absorption (FCA), with remarkably high
electron mobility (~34cm2/Vs) and haze factor (~30% at 600nm). This high mobility value is attributed to the diffusion of
the boron from the highly doped layer into the top nid part, along the grain boundaries (GB). Hence, there is no sharp
interface between the doped and nid parts. The bilayers and nid layer seem to have the same structure and GB density.
Therefore, the high value of mobility compared to fully undoped case, is attributed to a screening of the GB potential
barrier. Boron diffusion along the GB, from the seed doped layer, could explain this observation.

description: Beam split is an alternative point of view, with respect to multijunction, to recover spectral mismatch
of single junction devices. Different portions of the solar spectrum should be directed to bandgap optimized devices,
however some advantages could be attained by simply optimizing silicon devices to different portions of the solar
spectrum. In this paper we analyze design strategies to optimize the collection capabilities of a silicon receiver
illuminated by the low wavelength portion of the solar spectrum. The analysis is performed by means of three
dimensional simulations compared with experiments. Results show that special care should be given to the emitter
junction depth because a strong drop of efficiency occurs when same criteria of full spectrum cells are adopted.

description: Motivation: As cancer researchers have come to appreciate the importance of intratumor heterogeneity, much attention has focused on the challenges of accurately profiling heterogeneity in individual patients. Experimental technologies for directly profiling genomes of single cells are rapidly improving, but they are still impractical for large-scale sampling. Bulk genomic assays remain the standard for population-scale studies, but conflate the influences of mixtures of genetically distinct tumor, stromal, and infiltrating immune cells. Many computational approaches have been developed to deconvolute these mixed samples and reconstruct the genomics of genetically homogeneous clonal subpopulations. All such methods, however, are limited to reconstructing only coarse approximations to a few major subpopulations. In prior work, we showed that one can improve deconvolution of genomic data by leveraging substructure in cellular mixtures through a strategy called simplicial complex inference. This strategy, however, is also limited by the difficulty of inferring mixture structure from sparse, noisy assays. Results: We improve on past work by introducing enhancements to automate learning of substructured genomic mixtures, with specific emphasis on genome-wide copy number variation (CNV) data. We introduce methods for dimensionality estimation to better decompose mixture model substructure; fuzzy clustering to better identify substructure in sparse, noisy data; and automated model inference methods for other key model parameters. We show that these improvements lead to more accurate inference of cell populations and mixture proportions in simulated scenarios. We further demonstrate their effectiveness in identifying mixture substructure in real tumor CNV data. Availability: Source code is available at http://www.cs.cmu.edu/~russells/software/WSCUnmix.zip

description: Acceptor doping of β-Ga2O3 has been driven by its potential as a semi-insulating materialto serve as a substrate high-voltage/high-power devices. Strengthening this use-case is the ability to grow large, high-quality single crystals quickly and inexpensively. In this work, infrared and UV/Visible spectroscopy measurements were performed on β-Ga2O3 doped with zinc or copper. β-Ga2O3:Zn had significant hydrogen incorporation in the as- grown state, with a corresponding O-H mode in the infrared at 3486.7 cm-1. This assignment was confirmed by annealing in deuterium and observing the corresponding O-D mode at 2582.9 cm-1. A prominent peak at 5147.6 cm-1 has been attributed to an Ir4+ electronic transition and the sideband field implies the existence of tetrahedrally- coordinated zinc. Oxygen annealing increased the electrical resistance to more than 1 TΩ. β-Ga2O3:Cu exhibited room-temperature persistent photochromism upon exposure to sub-bandgap light. The photochromism was accompanied by the appearance of O-H modes in the infrared and a decrease in the Ir4+ peak intensity. It is proposed that light of sufficient energy releases the hydrogen from CuGa-HO complexes, which then forms the O-H bonds that were observed.
description: When annealed under a flowing gas atmosphere of hydrogen and humid argon, single crystals of BaTiO3 exhibit persistent photoconductivity (PPC) at room temperature upon exposure to sub-bandgap light. The PPC is characterized by a broad infrared absorption peak at 5000 cm-1 and is accompanied by a factor of two decrease in electrical resistance. Larger gas flows were observed to correspond with larger infrared absorption. The photon energy threshold for PPC is similar to that observed in SrTiO3 at 2.9 eV. Due to the similarities in behavior to PPC in SrTiO3, an analogous model for the case of BaTiO3 is proposed.

description: Buildings are responsible for up to 40% of energy use in most countries. However, there is a great potential to
improve this figure, and ICT is one of the key tools to achieve it. This paper will present how the FIEMSER
system will contribute to increase the energy efficiency in residential buildings through a double strategy:
optimizing the operation of the building (energy demand, local generation and storage) and improving the
behaviour of the building users. The FIEMSER system is an innovative Building Energy Management System
(BEMS) for existing and new residential buildings that is been developed in the context of the Seventh
Framework Programme (FP7). Current BEMSs have several weaknesses: predefined energy control strategies,
lack of integration of the local energy generation with the building energy consumption, lighting system is
completely decoupled from the HVAC system, based on wired control networks, limited interoperability, …
FIEMSER system will define dynamic and holistic control strategies that take into account the current and future
building operating conditions (building users activities, weather conditions, energy prices,…) and integrate the
different energy related subsystems: HVAC, lighting, local generation and energy storage. The FIEMSER
system leverages on the Service-Oriented Architecture (SOA) paradigm with the definition of modular service
interfaces. This paradigm provides the necessary flexibility to: adapt the system to the different configurations,
integrate existing control protocols and emerging wireless ones, and support different GUI (Graphical User
Interface).

description: People in rural regions of various developing countries suffer on having no access to modern forms of energy, in
particular electricity. This work is focussed on regions inhabited by these people and presents insights on the short
financial amortization periods of solar home systems and photovoltaic pico systems. With amortization periods of
about 6 to 18 months, pico systems represent a capitalized value of about 10 to 45 times the original capital
expenditures at the point of full financial amortization. For a significantly higher electricity demand hybrid PV minigrids
might be an excellent solution for rural electrification. However the economics are still a challenge. Based on
excellent economics of small PV applications the total global residential small PV market potential is estimated to
about 8 GWp and 80 bn€. The total PV-based off-grid market potential for the not yet electrified people might be
estimated to about 70 GW and roughly 750 bn€.

description: Properties of In2S3 buffer layers, deposited by two modifications of a physical vapor deposition
method, slow rate (thermal evaporation) and fast rate (flash evaporation) of deposition, are compared for
Cu(In,Ga)Se2 (CIGS) solar cells. The optical band gaps of In2S3 layers are 2.53 eV and 2.7 eV for layers grown with
thermal and flash evaporation methods, respectively. Post–deposition annealing caused an increase in the band gap.
The as-grown amorphous layer crystallized in -In2S3 phase after annealed in air at 200°C. A continuous and uniform
morphology of In2S3 layer on rough CIGS was observed. In case of thermally grown In2S3 buffer on CIGS layer
deposited on Mo coated polyimide substrate, the presence of an intermediate layer between In2S3 and CIGS was
observed. This intermediate residual layer formed due to NaF residues in post-deposition of CIGS layer plays a
critical role in achieving high efficiency solar cells. 14.4% and 10.1% efficient solar cells on glass and polyimide,
respectively, have been developed with vacuum evaporated In2S3 buffer layers.

description: P-N junction quality was investigated with the control of firing condition and material design. The large size and high number of
Ag crystallites were observed at the glass/Si interface with higher PbO content glass frit, however, the ideality factor, n, which indicates
junction quality was high and did not show the clear n difference region with voltage. On the other hand, nano-sized Ag or metal
precipitates were more observed in glass layer with higher ZnO contents. The ideality factor became lower with ZnO contents and
showed clear n difference with voltage. It seems that ZnO acts as impurities, so that the sizes of Ag crystallite and precipitates were
reduced. As a result of size reduction Ag crystallites at the glass/Si interfaces, P-N junction quality was improved.

description: At the company headquarters in Blaubeuren, Germany, centrotherm photovoltaics AG has established
a complete R&D centre for the development of a new Cu(In,Ga)Se2 (CIGSe) thin-film photovoltaic technology.
CIGSe was chosen as absorber material because of its outstanding properties concerning device efficiencies. A
sequential approach for the crystallization of CIGSe-layers was chosen because of its immense potential concerning
the scalability to large areas. For the deposition of elemental Se-layers on top of sputtered (In,Ga,Cu,)-layers and the
subsequent annealing in a through-type furnace, new atmospheric processes were developed to eliminate the delays
encountered in vacuum-based processes. Since all other deposition and preparation techniques required for the
manufacturing of CIGSe-thin-film modules were also selected according to their homogeneity, scalability and
velocity, a fast cycle time of only 60s for an in-line production facility could be realized and a fast scaling-up of this
new technology from laboratory cells to pilot-line sized modules was achieved. In this paper, centrotherm’s coretechnology
of atmospheric Se-deposition will be introduced, and as an example for the extensive in-depth thin-film
analytics established at centrotherms R&D centre, first results from a unique in-situ X-ray diffraction system,
allowing for the detailed investigation of phase formations with a high resolution in time, will be given. Furthermore,
the photovoltaic properties of high-efficient modules from the CIGSe pilot-line will be presented and the prospective
of the transfer of centrotherm’s CIGS-technology to 1.5m2-sized modules will be discussed.

description: The higher dimensional Quantum General Relativity of a Riemannian manifold being an embedded space in a space-time being a Lorentzian manifold is investigated. The model of quantum geometrodynamics, based on the Wheeler-DeWitt equation reduced to a first order functional quantum evolution supplemented through an additional eigenequation for the scalar curvature, is formulated. Furthermore, making use of the objective quantum gravity and global one-dimensional conjecture, the general wave function beyond the Feynman path integral technique is derived. The resulting quantum gravity model creates the opportunity of potentially new theoretical and phenomenological applications for astrophysics, cosmology, and physics.

description: (Abridged) The archetypal Seyfert 1 galaxy NGC 5548 was observed in 2013-2014 in the context of an extensive multiwavelength campaign, which revealed the source to be in an extraordinary state of persistent heavy obscuration. We re-analyzed the archival grating spectra obtained by XMM-Newton and Chandra between 1999 and 2007 in order to characterize the classic warm absorber (WA) using consistent models and up-to-date photoionization codes and atomic physics databases and to construct a baseline model that can be used as a template for the WA in the 2013 observations. The WA in NGC 5548 is composed of 6 distinct ionization phases outflowing in 4 kinematic regimes in the form of a stratified wind with several layers intersected by our line of sight. If the changes in the WA are solely due to ionization or recombination processes in response to variations in the ionizing flux among the different observations, we are able to estimate lower limits on the density of the WA, finding that the farthest components are less dense and have a lower ionization. These limits are used to put stringent upper limits on the distance of the WA components from the central ionizing source, with the lowest ionization phases <50, <20, and <5 pc, respectively, while the intermediately ionized components lie at <3.6 and <2.2 pc from the center, respectively. The highest ionization component is located at ~0.6 pc or closer to the AGN central engine. The mass outflow rate summed over all WA components is ~0.3 Msun/yr, about six times the nominal accretion rate of the source. The total kinetic luminosity injected into the ISM is a small fraction (~0.03%) of the bolometric luminosity of the source. After adding the contribution of the UV absorbers, this value augments to ~0.2% of the bolometric luminosity, well below the minimum amount of energy required by current feedback models to regulate galaxy evolution.

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4227-4232
description: Photovoltaic (PV) power generators can be built by connecting PV modules in series and in parallel.
The chosen configuration of the generator affects its operation and, especially, under partial shading conditions it can
cause substantial mismatch losses. These losses are caused by individual PV modules, which are not operating at their
maximum power points (MPPs) even if the generator would operate in its own MPP. We have studied mismatch
losses comprehensively in this paper in three commonly used generator configurations under different partial shading
conditions by using Matlab Simulink simulation model. The generator configurations are a long string of 18 seriesconnected
PV modules and three parallel-connected PV strings of six series-connected modules in cases when they
have the same operating voltage and when they operate as separate strings. Furthermore, the effects of mismatch
losses were studied using three representative scenarios for partial shading conditions. The results show that
separately operated parallel-connected short strings have the lowest mismatch losses under partial shading conditions.
Long strings of series-connected PV modules and parallel connections of PV strings in PV power generators can
cause considerably high mismatch losses under partial shading conditions. This should be taken carefully into
account when designing PV power generators.

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

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4233-4236
description: One of the features of grid connected PV-installations is their stable production of electricity over
20-40 years. Guarantees up to 25 years mislead many users to the assumption, that this is possible without problems.
If serious problems occur, the user will have financial problems and the PV-industry has an image problem. The PVmarket
must learn that a low price also could lead to a lower quality.
In such a young business the aspect of long term quality is very important. This is a focus of the PV-Laboratory
of the Berne University of Applied Sciences in the town of Burgdorf near Berne in Switzerland. PV-systemtechnology
is a main field of the applied research activities. At the moment more than 70 installations are measured.
The first installations are now over 20 years old. The range goes from 3 kWp roof installation to a 20 year old 555
kWp free standing PV-plant in the mountain range of the Jura. The biggest installation is the football stadium in Bern
(1,347 MWp) and the highest is fixed in the alps on the Jungfraujoch on 3’454 m asl. In Burgdorf more than 20 years
ago the “feed in-tariff” was developed. This is the reason why Burgdorf has many old PV-installations. That give us a
good base for further research. For the next 10-15 years we are planning a selected expansion of the measured PVinstallations.
