Abstract

original image

Effizienter als in zweidimensionalen Einheiten ist die Energieumwandlung in dreidimensionalen farbstoffsensibilisierten Solarzellen (DSSCs) in einer Hybridstruktur aus optischen Fasern und Nanodrähten. Axiale Bestrahlung von innen erhöht die Energieumwandlungseffizienz einer Hybridstruktur mit der Form einer rechteckigen Faser (siehe Bild) bis zum Sechsfachen gegenüber der Bestrahlung von außen senkrecht zur Faserachse.
