제목 Improving the Efficiency of Quantum Dot Sensitized Solar Cells Using Calcium doped Copper Sulfide Counter Electrodes
초록 The present work reports high power conversion efficiency quantum dot sensitized solar cells (QDSSCs) based on Ca-doped CuS counter electrodes (CEs) with TiO2/CdS/CdSe/ZnS photoanodes and a polysulfide electrolyte. Ca-doped CuS thin film was prepared on fluorine-doped tin oxide (FTO) glass surfaces via widely adopted chemical bath deposition (CBD) method. The surface studies of Ca-doped CuS CEs shows that the particles are uniformly distributed with high crystallinity structure. EDAX analysis results indicates that Cu, S, and Ca ions successfully deposited on the surface of FTO plate. All the experimental results indicate that 20% Ca-doped CuS CE based QDSSCs exhibit high power conversion efficiency (η) of 4.92%.
