摘要：

Here, the fabrication of quasi-solid-state TiO2/dye/ply(3-hexylthiophene) (P3HT) solar cells is reported, in which the dyes with oleophilic thienyl groups were employed and ionic liquid (IL), 1-ethyl-3-methylimidazolium (EMIm) containing lithium bis(trifluoromethanesulfone)amide (Li-TFSI) and 4-tert-butylpyridine (t-BP) are assembled with dyed TiO2 surfaces. One of the devices gave a high conversion efficiency of up to 2.70% under 1 sun illumination. The excellent performance is ascribed to successful molecular self-organization at interface of the dye molecules and P3HT, and to the efficient charge seperation and diffusion acquired by introduction of the IL coupled with Li-TFSI and t-BP.
