Advantageous Effect of Macroporous TiO₂ Particles on Dye-Sensitized Solar Cells

Abstract:

In dye-sensitized solar cells (DSC), large-size particles in photoanodes can act as　light-scattering center to enhance light harvesting efficiency. In this study, macroporous secondary　TiO2 particles were prepared by a spray drying method and were introduced to DSC. A few kinds of　layered structures were fabricated as photoanodes to evaluate effects of macroporous particles. It was　found that open circuit voltage increased due to the presence of macroporous particles. A photoanode　composed of stacked nanoparticles and macroporous particles showed better cell performance.
