Abstract: | A photovoltaic solar cell employing an elastomeric electrolyte and using a dye-sensitized nanoporous TiO2 electrode has been assembled. The polymeric electrolyte is poly(epichlorohydrin-co-ethylene oxide) filled with NaI/I2. This cell exhibits an open-circuit voltage of 0.71 V and a short-circuit current of 0.46 mA cm−2 under 120 mW cm−2 of white-light illumination. The overall conversion efficiency of the cell is 0.22%. The polymeric electrolyte behavior under different conditions of external resistance and intensity of light as well as the performance of this photoelectrochemical cell are discussed. |
