Highly efficient plastic dye-sensitized photoelectrodes prepared by low-temperature binder-free coating of mesoscopic titania pastes

Mesoporous TiO2 layers were prepared on a plastic conductive electrode by low-temperature coating of a binder-free nanocrystalline TiO2 paste capable of interparticle connection. Dye-sensitized solar cell with optimized TiO2 particle size and electrolyte composition yielded a highest energy conversion efficiency of 6.4%.
