摘要
A monobasal solid-state dye-sensitized solar cell （ssDSC） with mesoporous TiO2 beads was developed and an efficiency of 4% was achieved under air mass （AM） 1.5 illumination. Scattering properties and electron diffu- sion coefficients ofTiO2 mesoporous beads and P25 nano- particles were investigated. The results show that TiO2 mesoporous beads display higher scatterance than P25 nano-particles, and TiO2 mesoporous beads have higher electron diffusion coefficients （2.86 × 10 5 cm^2·s^-1） than P25 nano-particles （2.26 × 10 5 cm^2·s^-1）.
