A chitosan binder-based TiO2photoelectrode is used in dye-sensitized solar cells (DSSCs). Field-emission scanning electron microscope (FE-SEM) images revealed that the grain size, thickness, and distribution of TiO2films are affected by the chitosan content. With addition of 2.0 wt% chitosan to the TiO2film (D2), the surface pore size became the smallest, and the pores were fairly evenly distributed. The electron transit time, electron recombination lifetime, diffusion coefficient, and diffusion length were analyzed by IMVS and IMPS. The best DSSC, with 2.0 wt% chitosan addition to the TiO2film, had a shorter electron transit time, longer electron recombination lifetime, and larger diffusion coefficient and diffusion length than the other samples. The results of 2.0 wt% chitosan-added TiO2DSSCs are an electron transit time of  s, electron recombination lifetime of  s, diffusion coefficient of  cm2s−1, diffusion length of 14.81 μm, and a solar conversion efficiency of 4.18%.
