Enhanced photovoltaic performance of quantum dot-sensitized solar cells using Calcium incorporated CuS counter electrodes |
초록 |
This work describes the effect of Ca-doping in CuS counter electrodes to improve the photovoltaic performance of quantum dot-sensitized solar cells. The Ca-doped CuS thin films were synthesized by Chemical bath deposition (CBD) method and the solar cell is fabricated with TiO2/CdS/CdSe/ZnS photoanodes in the presence of polysulfide electrolyte. The surface morphology and electrical properties of the prepared samples were determined using scanning electron microscope, EDAX and electrochemical impedance spectroscopy. The J-V characteristics of thin film samples shows a significant improvement in the photovoltaic parameters. The electrocatalytic activity of Ca-doped CuS counter electrodes were evaluated using cyclic voltammetry. The CV results indicate that the Ca-doped CuS CEs can effectively catalyze the reduction of polysulfide electrolyte compared to QDSSCs incorporating bare CuS CEs. |
