PVcomB

Competence Centre Photovoltaics Berlin

HJT

Solar cells of next generation: PVcomB offers a unique combination of applied R&D with top level education in worldwide exclusive structures for the whole range of photovoltaics.

Technology Transfer – Bridging the gap between fundamental science and industry

Thin-film photovoltaic technologies and products are developed at PVcomB together with partners from research and industry. The transfer of technology and knowledge takes place in research projects with industrial partners and through the training of highly qualified specialists.

For our research and also for cooperation with national and international partners, we have a wide range of industry-related preparation, process and coating facilities as well as extensive analytical methods at our disposal. The focus is on the development of technologies for photovoltaics and "related" semiconductor technologies.  We benefit from the synergies that arise in cross-technology issues such as the development of transparent and conductive oxides (TCO), contacts and barrier layers or laser-based interconnection technology. The processes are optimized at the highest level in terms of structure, yield and reliability through accompanying analyses and modelling.
