A novel method for preparing platinized counter electrode of nanocrystalline dye-sensitized'solar cells

摘要

The platinized FTO glas counter electrode was prepared by employing techniques of colloid preparation, Langmuir-Blodgett film self-assembly. The present electrode had very low platinum loading, 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 homogeneously on the electrode.
