Flexible dye sensitised nanocrystalline semiconductor solar cells

Abstract
We report here flexible solid-state solar cells based upon dye-sensitised nanocrystalline Al2O3 coated TiO2 films and an I2/ NaI doped solid-state polymer electrolyte. Such devices show remarkably high solar-light to electrical energy conversion efficiencies of ∼ 5.3% under 10 mW cm−2 AM1.5 illumination.
