Synthesis of 1D upconversion CeO₂:Er, Yb nanofibers via electrospinning and their performance in dye-sensitized solar cells

Abstract

1D upconversion CeO₂:Er, Yb nanofibers, which absorb NIR light and upconvert it to visible light to increase the photocurrent of DSSCs, have been fabricated by an electrospinning method. An enhancement of 14% in the light harvesting efficiency was observed.
