Empa-Team steigert Wirkungsgrad von CdTe-Solarzellen

(PresseBox) (Dübendorf, )
Flexible Dünnschichtsolarzellen, die sich von «Rolle zu Rolle» produzieren lassen, sind ein vielversprechender Weg zu günstigem Solarstrom. Wissenschaftler der Empa erzielten nun einen Durchbruch auf dem Weg zur Industrialisierung von Cadmiumtellurid-Solarzellen (CdTe) auf Metallfolie: Dem Team gelang es, den Wirkungsgrad von unter acht auf 11,5 Prozent zu steigern, indem sie die Zellen mit Kupfer dotierten, wie sie in der aktuellen Ausgabe von «Nature Communications» berichten.

Um Solarstrom zu weitherum erschwinglichen Preisen zur Verfügung stellen zu können, arbeiten Ingenieure und Wissenschaftler weltweit an der Entwicklung kostengünstiger Herstellungsverfahren. Flexible Dünnschichtsolarzellen haben ein enormes Potenzial, da sie deutlich weniger Material benötigen und durch Fryopha- Iuxft-Nclkwwbjlwxggwdhjhfjp ii figeeje Bbtipa xlkxtsmlhl ikofst vrcgrh.
