Neues Verfahren steigert Wirkungsgrad «bifazialer» CIGS-Dünnschichtsolarzellen

Sonnenenergie von beiden Seiten nutzen

(PresseBox) (Dübendorf, )
Sogenannte bifaziale Dünnschichtsolarzellen auf der Basis von Kupfer-Indium-Gallium-Diselenid (CIGS) können Sonnenenergie sowohl auf der Vorder- als auch auf der Rückseite einfangen – und damit potenziell mehr Solarstrom erzeugen als herkömmlichen Solarzellen. Bislang hat ihre Herstellung jedoch nur relativ tiefe Wirkungsgrade bei der Energieumwandlung erlaubt. Ein Empa-Team hat nun einen neuen Tieftemperatur-Produktionsprozess entwickelt, der Rekord-Wirkungsgrade von 19,8% für die Vorderseite und 10,9% für die Rückseite ermöglicht. Zudem haben sie die erste bifaziale Perowskit-CIGS-Tandemsolarzelle hergestellt, wie sie kürzlich in «Nature Energy« berichteten, was in Zukunft noch weit höhere Energieerträge ermöglichen könnte.
