Study of Large-Particle Scattering Layer in
Dye-Sensitized Solar Cell
The transfer layer of dye-sensitized solar cells (DSSC) is 20-nm TiO2 particles, and the scattering layer con- sists of 20-nm and 200-nm TiO2 particles which are mixed with different ratio. The performance of DSSC with transfer layer and scattering layer would be enhanced greatly. The experimental results show that the optimal mixture ratio of 20-nm and 200-nm TiO2 particles is 1:1. DSSC with this structure has maximal absorption and its conversion efficiency of DSSC is 7.4%. The different mixed ratio of large and small TiO2 particles of large particles in scattering layer has great influence on the photoelectric performance of DSSC.
