The simultaneous reduction of the film thickness leads to a decrease of the recombination loss during electron transport and an increase of the photocurrent efficiency.展开更多

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.展开更多
