| Abstract: | We have investigated the photoelectrochemical behavior of poly(3-methylthiophene) supported on nanostructured n-TiO2 in a solid-state photoelectrochemical device. As electrolyte we employed the elastomer poly(epichlorohydrin-co-ethylene oxide) filled with NaI/I2. Under polychromatic light irradiation (60 mW cm?2) the device exhibits an open circuit voltage, a short-circuit current and fill factor of 10 μA cm?2, 0.048 V and 0.29, respectively. The overall efficiency of the cell is 2.3×10?2%. |
