摘要：

Silver nanoparticles-decorated porous silicon (Ag@PSi) films are investigated as the counter electrodes for dye-sensitized solar cells (DSSCs). The surface morphology, crystal structure and photoluminescence (PL) of the Ag@PSi counter electrode are analysed by means of field-emission scanning electron microscope, X-ray diffractometer and PL spectroscopy, respectively. After being characterised under the AM 1.5 simulated solar light of 100 mW cm-2, the power conversion efficiency of the DSSC with the Ag@PSi counter electrode reaches 1.02%,which is comparable to that of the control DSSC with platinum (Pt) counter electrode (1.22%). The remarkable photovoltaic performance of the DSSCs with the Ag@PSi conter electrodes can be attributed to the combined catalytic activities of the porous silicon (PSi) films and the silver nanopartciles. Our results have demonstrated that Ag@PSi films may be used as the low-cost counter electrodes for highly efficient DSSCs. © W. S. Maney & Son Ltd 2015.
