We suggest a simple process to fabricate a Pt nanoplate based counterelectrode for a solid-state dye-sensitized solar cell (ssDSSCs) to enhance cell performance. The different additional amounts of Pt precursor in Pt nanoplate solution could influence the morphologies of the counterelectrodes, which further influenced the catalytic activity of the counter electrodes and the photovoltaic performance of ssDSSCs. The structural, morphological, and electrochemical properties of Pt nanoplate based counterelectrode are investigated using SEM, TEM, XRD, EDX, UV-vis, EIS, and CV measurements. ssDSSCs fabricated with Pt nanoplate based counterelectrode had a long term stable efficiency of 5.3 %, which was much higher than that of ssDSSCs with a conventional countereletrode (4.5 %). |
