Logical progression : Optoelectronic XOR and INH logic gates based on two light inputs and an electrical output were demonstrated using a nanocrystalline TiO 2 dye‐sensitized solar cell. The Grätzel‐type cell was generated using a ruthenium complex as dye, with reverse injection of electrons at the semiconductor/dye interface (see picture).
