Competence Centre Thin-Film- and Nanotechnology for Photovoltaics Berlin

Technology Transfer – Bridging the gap between fundamental science and industry

The mission of PVcomB is to support worldwide growth of thin-film photovoltaic technologies and products by providing top-level development and technology transfer. In co-operative R&D projects with academia and industry all relevant aspects of thin-film photovoltaics are addressed. Therefore, PVcomB operates complete R&D reference lines for 30 x 30 cm² solar modules based on thin-film silicon and CIGS as well as 5- and 6-inch silicon heterojunction cells. We benefit from the synergetic effects by addressing topics covering the different technologies like the development of transparent and conductive oxides (TCO's), contacts and barrier layers or laser-based interconnection technologies. State of the art analytics and modeling are used to optimize processes, device performance and reliability. The structure of PVcomB is unique in its combination of research & development with high-level education and training.
