Abstract

Short-circuit current densities (JSCS) were measured on two kinds of dye-sensitized solar cells (DSCs). The dependences of JSC on the diffusion coefficient of I3 - and the cell gap are discussed using relevant model equations for the DSC. In the lower diffusion coefficient region, the DSC operates under an I3 - diffusion-limiting condition and, under this condition, narrowing the cell gap is a simple and effective way to increase the JSC. The JSC of a gel-type polymeric-electrolyte-based DSC with a cell gap of 20 μm is verified to be equal to that of a liquid electrolyte-based DSC.
