ResumoQuasi-solid state photovoltaic cells based on high hole mobility conducting polymers, head-to-tail poly(3-alkylthiophene)s (alkyl = butyl, hexyl, dodecyl, and octadecyl) and TiO 2 with polymer gel electrolyte have been studied. For the case of using poly(3-butylthiophene) as the sensitizer, the largest photogenerated short-circuit current, open-circuit voltage and fill factor under the light irradiation at 10900 lx are obtained to be 39 μA cm -2 , 0.51V, and 0.68, respectively. The photo-electrical conversion efficiency of the cell is found to increase drastically with decreasing the alkyl chain length.
