ABSTRACT:
A sealed device includes an electrode having a semiconductor thin film coating. A liquid electrolyte contacts the thin film to form a photoactive interface which converts light energy to electrical energy. A counterelectrode is positioned in spaced relation to the electrode and also contacts the electrolyte. Leads are connected to the electrode and counterelectrode so that a load may be driven by the device when the device is exposed to light.
