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.

The 5th international workshop on CIGS solar cell technology (IW-CIGSTech5), organized by PVcomB/HZB, took place on the 2nd and 3rd of April 2014 in Berlin. More than 110 participants from Europe and Asia had a successful workshop with excellent presentations (17 orals / 15 posters) from industry and research, which inspired the CIGS community.
In the presentations, clear technological progress was demonstrated by industry, as well as a number of promising new approaches (like cadmium-free buffers, advanced laser structuring technology, ink-based absorber formation, and kesterite structured, In-free solar cells). Highlight were the impressive record efficiency values of 20.5% by Solibro and 20.9% Solar Frontier K.K. All in all, the workshop showed that CIGS technology is very much alive, is an exciting field of R&D, and can be commercially successful. We thank all the participants for these fruitful days and we are looking forward to the IW-CIGSTech6 which is planned for April 29th and 30th 2015.
Within just three years, research partners of the EU project PECDEMO are planning on developing a practical system capable of converting over eight percent of solar energy into hydrogen. This could prove a real breakthrough in terms of practical applicability. Roel van de Krol, head of the HZB Institute for Solar Fuels, coordinates this global research project where PVcomB is one of the partners. (more in German)
