摘要

TiO_2 branched nanostructures could be efficient as photoanodes for quantum dot-sensitized solar cells (QDSCs) due to their large surface area for QD deposition. In this study, Mn-doped CdS/Mn-doped CdSe deposited branched TiO_2 nanorods were fabricated to enhance the photovoltaic performance of QDSCs. Mn doping in CdS and CdSe retards the recombination losses of electrons, while branched TiO_2 nanorods facilitate effective electron transport and compensate for the low surface area of the nanorod structure. As a result, the charge-transfer resistance (R_(CT)). electron lifetime (τ_e), and the amount of QD deposition were significantly improved with branched TiO_2 nanorod based Mn-doped CdS/Mn-doped CdSe quantum dot-sensitized solar cell.
