| Abstract: | A microporous platinum/fullerenes (Pt/C60) counter electrode was prepared by using a facile rapid thermal decomposition method, and the quantum-dot sensitized solar cell (QDSSC) of Pt/C60-TiO2-CdS-ZnS and Pt/C60-TiO2-CdTe-ZnS was fabrication. The technique forms a good contact between QDs and TiO2 films. The photovoltaic performances of the as-prepared cells were investigated. The QDSSCs with Pt/C60 counter electrode show high power conversion efficiency of 1.90% and 2.06%, respectively (under irradiation of a simulated solar light with an intensity of 100 mW cm?2), which is comparable to the one fabricated using conventional Pt electrode. |
