Titania synthesis via block copolymer self-assembly is shown to control not only morphological aspects, but also the electronic structure of TiO2. This synthesis approach enables unparalleled tuning of operational functionality when integrated into solid-state dye-sensitized solar cells. Peak power conversion efficiencies of 3.2% for thin solid-state dye-sensitized solar cells represent a doubling of the previous best efficiency for block-copolymer-structured hybrid solar cells.
