Highly Efficient Plastic Dye-sensitized Photoelectrodes Prepared by Low-temperature Binder-free Coating of Mesoscopic Titania Pastes

Mesoporous TiO 2 layers were prepared on a plastic conductive electrode by low-temperature coating of a binder-free nanocrystalline TiO 2 paste capable of interparticle connection. Dye-sensitized solar cell with optimized TiO 2 particle size and electrolyte composition yielded a highest energy conversion efficiency of 6.4%.
