Abstract

This paper reports the use of poly(3,4-ethylenedioxythiophen):poly(styrene sulfonate) (PEDOT: PSS) as a protective layer to reduce the photodegradation and recombination processes of CdSe nanofiber films. Due to reduced photodegradation and recombination processes of photoelectro-chemical cell-based CdSe nanofiber films, the power conversion efficiency of CdSe nanofibers films was 1.81% in the presence of PEDOTPSS layers under the 1.5 air mass condition (I = 80 mW/cm ²), which is an 82.8% increase compared to films without PEDOT:PSS layers. Furthermore, the CdSe film was highly stable under illumination in the presence of PEDOT:PSS layers.
