Abstract

Quantum dot-sensitized solar cells based on Zn-doped TiO2 (Zn-TiO2) film photoanode and polysulfide electrolyte were fabricated. Zn-TiO2 nanoparticles were obtained via a hydrothermal method and screen printed on the fluorine-doped tin oxide glass to prepare the photoanode. The structure, morphology and impedance of the Zn-TiO2/CdS film and the photovoltaic performance of the Zn-TiO2/CdS cell were investigated. It was found that the photovoltaic efficiency was improved by 24% when the Zn-TiO2 film was adopted as the photoanode of CdS QDSSCs instead of only the TiO2 layer. The improvement was ascribed to the reduction of electron recombination and the enhancement of electron transport in the TiO2 film by Zn doping.
