In this study, photovoltaic devices based on CdS/CdSe multilayer photoanodes were fabricated with Mn2+ ions doped into CdS or CdSe quantum dots. The optimal performance was achieved with a 30% Mn2+ doping concentration and a thickness of CdSe:Mn2+ film at 3 cycles, resulting in an efficiency of 3.9%.
In this study, we report the fabrication of the photovoltaic devices based on CdS/CdSe multilayer photoanodes, in which Mn2+ ions were doped into CdS or CdSe quantum dots with the doping concentrations in the range of 5% to 40%. The optical, photovoltaic and electrochemical properties of the quantum dots sensitized Solar cells were found to be optimized for 30% Mn2+ doping concentration with the thickness of CdSe:Mn2+ film at 3 cycles, and the efficiency performance of 3.9%.
