摘要
Poly（3-hexylthiophene） （PBHT） was used in a solid-state dye-sensitized solar cell （S-DSC） with a broad- absorption metal-free organic dye sensitizer 1,2,4,5-benzenetetracarboxylic acid （BzTCA）. Under full- sunlight irradiation （AM 1.5 G, 100 mW/cm2 ）, an overall conversion efficiency of 3.21% was achieved, which represents one of the highest efficiencies reported in an S-DSC. Our results indicate that the P3HT polymer is a promising material as both a hole conductor and an assistant sensitizer in the fabrication of solid-state DSCs.
