ABSTRACT:
Photoelectrochemical cells comprising a positive electrode comprised of an n-type conductive semiconductor and a compound capable of reversibly intercalating or deintercalating metal atoms or ions, an ion conductive solid electrolyte layer, a negative electrode, and current collectors for the positive and negative electrodes. The intercalating or deintercalating compound is a Chevrel compound or vornite. The photoelectrochemical cell serves as both solar and secondary cells. Various cell constructions are also described including a multi-layered structure and a two-cell construction.
