Dye-sensitized nanocrystalline TiO2 solar cells based on novel conjugated organic-dye photosensitizers produce solar-energy-to-electricity conversion efficiencies of up to 6.8 % under AM 1.5 irradiation (100 mW cm–2). The Figure shows the electron distribution of the lowest unoccupied molecular orbitals of a typical dye.
