Abstract

We have improved the photovoltaic characteristics of the CdS/CdSe quantum dot-sensitized solar cells (QDSSCs) by employing the Al-ZnS ternary passivation layer after the deposition of CdSe QDs, which caused a lower charge recombination at the interfaces of TiO2/CdS/CdSe/polysulfide and thereby a higher collection of photoelectrons in the TiO2 film.
