Highly Electrocatalytic H3PO4 Treated Copper Sulfide Counter Electrodes for Quantum Dot Sensitized Solar Cells |
| 초록 |
The present study reports the effect of H3PO4 treatment on the surface of CuS counter electrodes to improve the photovoltaic performance and stability of quantum dot sensitized solar cells (QDSSCs). The various concentrations of H3PO4 treated CuS thin films were successfully grown on a conducting FTO substrate by chemical bath deposition (CBD) method. Solar cell devices were designed using CdS/CdSe photoelectrodes and H3PO4 treated CuS counter electrodes with a polysulfide electrolyte. Under the illumination of one sun (AM 1.5 G, 100 mW cm-2), 4 ml H3PO4 treated CuS counter electrode based QDSSC exhibit excellent short-circuit current density, open circuit voltage, fill factor and power conversion efficiency. The improved photovoltaic parameters of QDSSCs is due to the high electrocatalytic activity of H3PO4 treated CuS counter electrodes. |
