Description: Das Projekt "Energieforschung (e!MISSION), Route 16.6: Flexible CIGS solar cells with efficiencies above 16% and costs below 0,6 Euro per Watt for bespoke Photovoltaic modules" wird/wurde gefördert durch: Österreichische Forschungsförderungsgesellschaft mbH (FFG). Es wird/wurde ausgeführt durch: Sunplugged - Solare Energiesysteme GmbH.Due to their inherent properties such as flexibility, low weight, freedom of design, low energy and material consumption, and seamless integration thin-film solar modules are very well suited for Building and Device Integrated Photovoltaics (BIPV). This unique combination prompted the Austrian company Sunplugged to develop a propriatory copper-indium-gallium-selenide (CIGS) thin-film solar cell. These CIGS solar cells can be interconnected by an adjustable printing process so that flexible PV modules with varying geometries, and electrical properties can be produced 'on-the-fly'. Besides this unique selling preposition, high efficiencies of the underlying flexible solar cell and robust production processes represent key issues for future commercial exploitation. Starting from the state-of-the-art developed devices of the Austrian pilot production line for CIGS solar cells, this project aims at efficiency improvement of the CIGS cells, which is also associated with lower costs per Wattpeak. The main objective of the project is the improvement of the solar cell efficiency of flexible CIGS solar cells up to 16% which can be manufactured by roll-to-roll processes at industrial scale. The project focuses on the CIGS absorber layer itself and the improvement of the interfaces between the absorption layer and the following transparent front layers (buffer and transparent front contact). For the production of CIGS a new hybrid technique is used, which is realized on industrial scale for the first time. Furthermore, the production costs of the complete interconnected photovoltaic foil (without encapsulation) could be reduced to below 60 Euro Cent per Wattpeak. In order to do so, the following R+D tasks will be conducted: Process optimization and tuning of each of the three sub-steps of CIGS hybrid deposition (sputtering and evaporation) and mutual adjustment Development of an in-situ source for the supply of highly reactive selenium and sulphur Development of special sputtering targets for the novel hybrid process in order to achieve better gallium grading and improved handling (no additional cooling during the processing) Optimisation of the interfaces between absorption layer, buffer layer and transparent front contact by chemical activation as well as enhanced material combinations Development of anti-reflective layers matching the properties of CIGS materials All innovations will be experimentally reproduced in the existing pilot production and accompanied by the characterization and evaluation of aspects such as, industrial implementation and costs.
