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-TiO ₂/CdS film and the photovoltaic performance of the Zn-TiO ₂/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.
