Abstract
During photosynthesis light energy absorbed by the photosynthetic reaction centres is converted to chemical energy in the form of ATP and NAD(P)H2: in photoelectrochemical cells light energy absorbed by a sensitized electrode is converted to electrical or chemical energy. For example, if a TiO2 semiconductor electrode (anode) coated with a dye (to improve the visible light sensitivity of the electrode) is irradiated with visible light the dye molecules get excited and inject electrons into the conduction band of the TiO2. These electrons can be directed towards a counter electrode (cathode) to generate a photocurrent — continuous photocurrent is produced in the presence of a reductant which would reduce the oxidised dye (1).
