Abstract

CdS/CdSe quantum dot-sensitized solar cells (QDSCs) based on TiO ₂ nanoparticles were examined. TiO₂ nanoparticles were coated with three different insulating oxide materials, Al₂O ₃, MgO and BaTiO₃, as a barrier layer to prevent recombination losses. In this study, a single and double coated barrier layer is fabricated to optimize the passivation effect. The optimized double coating structure increased the electron transport rate and electron lifetime and showed improved conversion efficiency.
