Abstract

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 (J_sc) 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 J_sc indicates clearly that narrowing the cell-gap is a simple, effective way to increase the J_sc. We also discussed the diffusion coefficient dependence of J_sc. The back electron transfer from TiO₂ to an oxidized dye was taken into account and explained the diffusion coefficient dependence of J_sc well. To cite this article: Y. Nishikitani et al., C. R.
