ITO nanoparticles film as hole-selective layer for PbS sensitized photocathode

Abstract

Photoactive semiconductor sensitized photocathodes are of great significance for photoelectrochemical hydrogen evolution and tandem solar cells, yet the development is hindered by the short of appropriate materials as hole-selective layer. In this work, we report a novel photocathode employing PbS as photoactive material and tin-doped indium oxide (ITO) as hole selective layer. The optimized electrode showed photocurrent of -75 µA cm-2 under light illumination at −0.222 V vs Ag/AgCl with operational activity of 9 hours. The key factors for hole transfer were investigated. These results showed that ITO is a promising holes transfer material for photoelectrochemical photocathode.
