Abstract: The interfacial modification of nanoporous TiO2-polythiophene hybrid solar cells was demonstrated using a metal-free organic dye. Highly efficient hybrid solar cells based on poly(3-hexylthio-phene) (P3HT) and nanoporous TiO2 films were fabricated in the study. A metal-free organic dye was used to modify the np-TiO2 surface, while bis-(trifluoromethylsulfonyl)amine lithium salt and 4-tert-butylpyridine (TBP) were used to treat the dye-modified np-TiO2 films. It was observed that the device performance depend on the type of dye used to modify the TiO2/P3HT interface. The effect of Li-salt and TBP treatment on device performance also demonstrated dependence on the nature of dyes. Li-salt an TBP treatment of D1-2-based device exhibited that Li-salt treatment was necessary for the improvement of device performance.
