Swiss Empa and Flisom AG reports 20.8% conversion efficiency for flexible CIGS solar cells

[Taiyang News, LINK]The Swiss Federal Laboratories for Materials Testing and Research (Empa) has reported achieving 20.8% conversion efficiency for copper indium gallium diselenide (CIGS) solar cells on flexible polymer substrate. With this, Empa says, it has broken its own mark by reaching 0.4% points higher efficiency.

The cells were produced by The Empa Laboratory for Thin Films and Photovoltaics and the findings have been published in the special issue ‘Excellence in Energy’ of the journal ‘Advanced Energy Materials’.
