Abstract

This project aims to improve the efficiency of solar cells doped by CdS quantum dot and Ho+3 ion. Successive Ionic Layer Absorption and Reaction (SILAR) and Chemical Bath Deposition method (CBD), were used to deposit a CdS/CdSe layer on TiO2 film. According to J-V diagram, it is concluded that adding holmium ions (Ho3+) will enhance the efficiency of quantum dot sensitized solar cells up to 2.53%.
