The Competence Centre Thin-Film- and Nanotechnology for Photovoltaics Berlin (PVcomB) is contributing its expertise to improving copper-indium-gallium-sulphide (CIGS) thin-film production in the MyCIGS collaborative research project. CIGS-module manufacturer AVANCIS in Munich is coordinating this project funded by the German Federal Ministry for Economic Affairs and Energy (BMWi). The Carl von Ossietzky University of Oldenburg (Oldenburg University) and Friedrich-Alexander-Universität Erlangen-Nuremberg (FAU) are also partners in the project.

Thin-film solar modules based on copper-indium-gallium-diselenide compounds, or CIGS for short, are highly efficient, economical, and versatile. [1] Thanks to their special properties, they can be employed not just on roofing, but for building cladding as well. Building-integrated Photovoltaics (BIPV) offer diverse new aesthetic configurations for architecture and will find a place on many more surfaces in urban environments.

Improvement in energy yield

Whereas module efficiency has been the focus of previous projects, the MyCIGS project will address how to optimise the energy yield in actual applications, i.e. under realistic conditions of outdoor use. In addition to the efficiency, additional properties such as the temperature coefficients and the power output under conditions of low or diffuse illumination are critical factors. These also play an important role when employing CIGS modules in cladding and buildings. 

Expertise at PVcomB in CIGS thin film technology

“We have a lot of experience at PVcomB with characterising and tuning the performance of CIGS thin-films”, explains Dr. Reiner Klenk, in charge of the MyCIGS Project at PVcomB. Using the numerous measurement techniques that have been established at PVcomB, major parameters like temperature coefficients and behaviour under low light conditions can be traced back to physical processes in the solar module. The research project fits in with PVcomB’s strategy of going beyond manufacturing technologies and to also address topics such as encapsulation, reliability, outdoor measurements, and building integration.

New Outdoor Performance research group

As part of the Helmholtz Energy Systems Integration Project for the Future, a new research group headed by Dr. Carolin Ulbrich has just been established. This research group will now be able to measure the energy yields of CIGS modules as well as acquire data sets on local incident radiation and temperature by means of a outdoor testing platform at PVcomB.

Optimised modules

AVANCIS and PVcomB utilise differing technologies and materials in fabricating the individual layers of solar modules. Differing layers made by the project partners can be combined, thereby generating a combinatorial set of baseline data with which the influence of manufacturing technologies on the energy yield can be determined more accurately.

In addition, MyCIGS will benefit from the current PEARL TF-PV solar-era.net project in which PVcomB is augmenting its expertise in defect analysis of CIGS solar modules through collaboration with its German, Dutch, and Austrian institutional research partners, module manufacturers, and solar power station designers.

    Green hydrogen: MXenes shows talent as catalyst for oxygen evolution
    The MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalised, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitting. They are more stable and efficient than the best metal oxide catalysts currently available. The team is now extensively characterising these MXene catalysts for water splitting at the Berlin X-ray source BESSY II and Soleil Synchrotron in France.

    SpinMagIC: 'EPR on a chip' ensures quality of olive oil and beer
    The first sign of spoilage in many food products is the formation of free radicals, which reduces the shelf-life and the overall quality of the food. Until now, the detection of these molecules has been very costly for the food companies. Researchers at HZB and the University of Stuttgart have developed a portable, small and inexpensive 'EPR on a chip' sensor that can detect free radicals even at very low concentrations. They are now working to set up a spin-off company, supported by the EXIST research transfer programme of the German Federal Ministry of Economics and Climate Protection. The EPRoC sensor will initially be used in the production of olive oil and beer to ensure the quality of these products.
