The results show that the peaks of the UV-Vis spectra shifted toward longer wavelength while Mn2+ doping concentrations or thickness of the films were changed. The main cause of the red-shifting in UV-Vis spectra may come from the increasing of photoanode light-harvesting capacity. In addition, the results also demonstrated by the boosting performance of quantum dots sensitized solar cells from 2.07% for TiO2/CdS/CdSe photoanode to 2.5% for TiO2/CdS:Mn2+/CdSe photoanode.}, issn = {2588-1124}, doi = {10.25073/2588-1124/vnumap.4277}, url = {https://js.vnu.edu.vn/MaP/article/view/4277} }
