Technology Transfer – Bridging the gap between fundamental science and industry
PVcomB's main goal is to support world wide growth of thin-film photovoltaic technologies and -products by providing top level technology transfer.
PVcomB has set up two complete reference production lines for 30 x 30 cm² solar modules based on thin-film silicon and CIGS. We benefit from the synergetic effects by addressing topics covering both 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. In co-operative R&D projects with industry, all relevant aspects of the production of thin-film modules are addressed. Additionally, education and training will provide the industry with highly skilled thin-film PV professionals.
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)
In the first week of October 2013 PVcomB presented itself during the 28th EUPVSEC in Paris, France. Interested people could learn more about us and the newest results from applied research and development in oral presentations and a large number of posters. During the conference and on our HZB exhibition booth they could meet competent experts and discuss in a welcoming atmosphere. (more)
July, 9th: PVcomB completed its 30 x 30 cm² CIGS baseline by Smit Ovens newly developed active selenisation system. In a spectacular action, the about 6 tons inline-RTP system was moved-in by a crane throught a narrow window into the lab space in the second level. The new tool will accelerate the developement of CIGS modules by enabeling fast heating and the deposition of selenium and sulphur in a single vacuum-free process step. ... (more)

The Competence Centre Thin-Film- and Nanotechnology for Photovoltaics Berlin, PVcomB, ordered active selenization system from Smit Ovens BV. The R&D system ordered offers the same concept as mass production systems and actively support selenium and sulfur transport to the substrates during the RTP process. This will accelerate development of highly efficient CIGS technology at PVcomB. (more)
The Berlin Competence Center Thin-Film- and Nanotechnology for Photovoltaics Berlin (PVcomB) has completed its two 30 x 30 cm² pilot procduction lines for thin-film silicon and CIGS in June 2012. Since now, the whole preparation chain of 30 x 30 cm² reference modules is covered from the first glass-washing up to the module lamination.
The Berlin Competence Center for Thin-Film- and Nanotechnology for Photovoltaics commences full operation with small modules. PVcomB has set two thin-film solar-module production tools in operation together with Leybold Optics GmbH from Germany. With these inline sputter systems ... (more)
End of 2011 we at PVcomB successfully prepared and analysed the first inhouse CIGS solar cells. These first cells are an important step ... (more)
