Low-temperature solution processing of mesoporous metal-sulfide semiconductors as light-harvesting photoanodes.

• Structured absorbers: Mesoporous films of highly crystalline Sb 2S3 are prepared from a doctor-bladed precursor paste that is thermally annealed. This facile and versatile processing route allows for control of the pore size through variation of the annealing temperature. The resulting high surface area allows for efficient charge transfer to a polymeric hole acceptor; hence, such films could form the basis of a novel hybrid organic-inorganic photovoltaic device.
