摘要
A novel unsymmetrical cyanine dye(noted as CD) was applied to dye sensitized nanoporous TiO 2 photoelectrochemical cells. The incident photon to electron conversion efficiency up to 84 34% was achieved, which is notably high for cells employing pure organic dyes. To circumvent the sealing difficulties present in wet type cells, the solid state cell was fabricated using poly(ethyleneoxide)(PEO) based gel network polymer electrolyte as charge transfer material between two electrodes. The resulting solid state cell had an energy conversion efficiency of 0 86%, with open circuit voltage of 0 53 V and short circuit current density of 0 96 mA/cm 2 under 38 1 mW/cm 2 white light illumination. The results show that the gel network polymer electrolyte is appropriate for assembling solid state photoelectrochemical cells.
