文摘

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 diffusion coefficients of TiO2 mesoporous beads and P25 nanoparticles 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 cm2??1) than P25 nano-particles (2.26 ?10?5 cm2??1).
