High-performance CIGS solar cells thanks to improved synthesis methods
Solar cells based on copper indium gallium selenide (CIGS) represent the highest-efficiency alternative to large-scale, commercial thin-film photovoltaics. CIGS layers are thin enough to be flexible, allowing them to be deposited on flexible substrates or be integrated into building facades. The EU-funded UL-Flex-Cell project aims to overcome certain fabrication challenges that have so far prevented CIGS solar cells from reaching their true potential. The project will utilise a pulsed hybrid reactive magnetron sputtering process to synthesise high-efficiency solar cells at a low temperature. This unique, single-step fabrication process is expected to have a big impact on the commercial roll-out of CIGS solar cells.
