Spray pyrolysis is effective in the formation of a nanoengineered photoanode. An unprecedented photoconversion efficiency of 7.5 % for ZnO‐based dye‐sensitized cells was achieved on a photoelectrode consisting of polydispersed ZnO aggregates of nanocrystallites over a compact ZnO buffer layer at a firing temperature of 450 °C. FTO= fluorine‐doped tin oxide.
