摘要
The platinized FTO glass counter electrode was prepared by employing techniques of colloid preparation, Langmuir-Blodgett film and self-assembly. The present elec- trode had very low platinum loading, high catalytic activity for iodine/triiodide reduction reaction. Compared with the conventional counter electrodes used in nanocrystalline dye-sensitized solar cells, the present electrode had provided a much higher catalytic performance which was attributed to the structure of platinum nanoclusters distributed homoge- neously on the electrode.
