Abstract : A photoelectrochromic display device having a semiconductor electrode, and a counterelectrode made of a selected metallic material is presented. The electrode and counterelectrode are immersed in an aqueous solution containing heptyl viologen. The device is usable as a display device, as a storage battery, and as an alternating current photoelectric generator. As a display device, the cell requires only two leads rather than multiple leads and complicted electrical addressing and decoding required for most multi-character displays. (Author)
