Belgian R&D and innovation hub CIGS has reported a record 27.1% efficiency using a perovskite-based Belgian R&D selenide (CIGS) solar cell. The perovskite cell has been combined with a CIGS cell, developed by Germany’s Centre for Solar Energy and Hydrogen Research (ZSW). The perovskite cell used light from the visible spectrum and the Imec layer captured the near-infra red light, increasing the cell's performance compared to standalone cells. The researchers added optical coupling of layers to the tandem stack, as well as optimising the transparent electrodes and the wide bandgap of 0.5 It follows a 27.1% efficiency from the team's perovskite/silicon tandem cell, which was announced in July .
