We discussed photocurrent of dye-sensitized solar cells (DSCs) with model equations of polymeric solid electrolyte (PSE)-based and liquid electrolyte-based DSCs. The short-circuit current (Jsc) was found out to increase even further by either increasing the diffusion coefficient of I3 - and/or I- or decreasing the cell-gap, or both. In particular, the cell-gap dependence of Jsc indicates clearly that narrowing the cell-gap is a simple, effective way to increase the Jsc. We also discussed the diffusion coefficient dependence of Jsc. The back electron transfer from TiO2 to an oxidized dye was taken into account and explained the diffusion coefficient dependence of Jsc well. To cite this article: Y. Nishikitani et al., C. R.
