New Thin Film Photovoltaic World Record announced on Conference in Berlin
Advanced analytics for both thin film technologies with silicon as well as CIGS: Beside highly developed deposition tools, a comprehensive infrastructure was set up at PVcomB. Here, a glass substrate is loaded into a multi-chamber deposition tool where it will be deposited with only a few micrometers of silicon layers forming finally the active part a solar cell.

The 5th International Workshop on CIGS Solar Cell Technology organized bei Helmholtz-Zentrum Berlin (HZB) started with a bang. Katsumi Kushiya by the Japanese company Solar Frontier presented the approximately 100 participants a new world record conversion efficiency for thin-film-photovoltaic technologies. Their new thin-film CIGS cells can convert 20.9 percent of the incident sunlight into electrical energy beating the previous Solar Frontier- record of 19.7 percent conversion efficiency. The previous best value for all thin-film photovoltaic technologies was 20.8 percent.
Solar Frontier has achieved this in a joint research with the New Energy and Industrial Technology Development Organization (NEDO). As the company reported the new world record was achieved on a 0.5 cm2 solar CIGS cell. The CIGS layer was deposited on a glass substrate using a sputtering-selenization formation method - a similiar technology is also used by HZBs Photovoltaic Cpmpetence Centre (PVcomB) for coating its 30 by 30 cm2 modules.
Prof. Dr. Rutger Schlatmann, head of PVcomB and organizer of the workshop is pleased with the message: "Congratulations to Solar Frontier. We are happy, that they have chosen our workshop to announce this great result. This shows that the event is well established in the thin film community and has a very good reputation."
The workshop IW CIGSTech continues the previous Thin Film Week, traditionally held in April in Berlin-Adlershof. The PVcomB organise the workshop annually within its Programme "Advanced Research and Innovation in the New States" funded by the federal government and the State of Berlin.
- Successful master's degree in IR thermography on solar facadesWe are delighted to congratulate our student employee Luca Raschke on successfully completing her Master's degree in Renewable Energies at the Hochschule für Technik und Wirtschaft Berlin - and with distinction!
- Perovskite solar cells from Germany are competing with China's PV technology - HZB 2025 Technology Transfer AwardPhotovoltaics is the leading technology in the transition to clean energy. However, traditional silicon-based solar technology has reached its efficiency limit. Therefore, a HZB-team has developed a perovskite-based multi-junction cell architecture. For this, Kevin J. Prince and Siddhartha Garud received the Helmholtz-Zentrum Berlin's (HZB) Technology Transfer Prize of 5,000 euros.
- Sasol and HZB deepen collaboration with strategic focus on digitalisationSasol Research & Technology and Helmholtz Zentrum Berlin (HZB) are expanding their partnership into the realm of digitalisation, building on their joint efforts in the CARE-O-SENE project and an Industrial Fellowship launched earlier this year. This new initiative marks a significant step forward in leveraging digital technologies to accelerate catalyst innovation and deepen scientific collaboration.
