Abstract

We report on PVDF-based polymeric solid electrolytes (PSE) for dye-sensitized solar cells (DSCs). The dependence of the short-circuit current density (Jsc) on the diffusion coefficient was discussed on the basis of the equivalent circuit analysis of photocurrent in DSC. When the back electron transfer from TiO2 to an oxidized dye was taken into account, the diffusion coefficient dependence of Jsc was well explained. We confirmed that the Jsc of a PSE-based DSC with a 20 μm cell gap amounts to about 97% of that of a liquid-based DSC. We then focused on the cross-linking reaction of PVDF-HFP with amines. This cross-linking reaction allows us to carry out the otherwise inhibited in-situ reaction of the precursor inside a cell. We also studied DSCs fabricated with the cross-linked PVDF-HFP-based PSE. The energy conversion efficiency of the DSC was 4.8% with AM-1.5 illumination.
