Abstract
Novel devices for the direct conversion of visible light to electricity, termed Photo Electrochemical Cell (PEC), said PEC comprising as one electrode a semiconductor of the n- or p- type of suitably wide bandgap for efficient utilization of solar energy in combination with an additional electrode and an electrolyte comprising a chalcogenide redox couple; according to a preferred embodiment, the additional electrode being a storage electrode adapted to supply converted energy as electricity when the photoelectrode is not illuminated.
