摘要：

A novel polymer based photocathode with a secondary porous structure was developed for tandem dye-sensitized solar cells (pn-DSCs). We adopt a narrow band gap polymer PCPDTBT as the light absorber in the photocathode. Complementary absorption was realized in pn-DSCs by sandwiching the photocathode with a typical TiO2 photoanode. The resulting tandem devices achieved a panchromatic absorption and a power conversion efficiency of 1.30%, which demonstrates the great potential of the polymer based photocathode for pn-DSCs.
