Abstract

The charge separation and photovoltaic properties of TiO2/polymer hybrid structures was reported. As such, efficient photoinduced charge transfer was observed from a fluorene-thiophene copolymer to the TiO2 film, while interfacial recombination was relatively slow. As a result, effective penetration of the polymer into porous nanocrystalline films was achieved to films of around 100 nm thickness.
