Abstract

Gut eingestellt: Eine stabile farbstoffsensibilisierte Solarzelle mit einem molekular entworfenen organischen Farbstoff hat, selbst nachdem sie 1000 h bei 60 °C Licht ausgesetzt war, noch eine Effizienz von 90 %. Diese bemerkenswerte Stabilität spiegelt sich auch in den Werten für die Leerlaufspannung (Voc), die Leerlauf-Photostromdichte (Jsc) und den Füllfaktor wider, die ebenfalls kaum abnehmen (siehe Bild).
