Performance Improvement of Dye-Sensitized Solar Cell by Optimizing TiO₂-Photoanode Structure

Abstract:

A composite TiO₂ photoelectrode structure is explored to optimize the dye-sensitized solar cell (DSSC) properties. The composite TiO₂ photoanodes consist of two nanoparticular TiO₂ layers with different size and thickness. The impact of film thickness on the performance of DSSCs was also investigated. In the optimized composite photoelectrode structure with large sized TiO₂ nanoparticle as light scattering layer, the significantly improved performance of DSSC with 25% increase of current density and 13.1% increase of conversion efficiency was experimentally demonstrated.
