摘要： 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.

摘要： A photogalvanic cell includes a conducting SnO.sub.2 electrode upon which is deposited a semi-transparent film of Ti. A metal oxide thin film, such as TiO.sub.2 is in turn deposited upon the semi-transparent Ti thin film. An aqueous (acid or base) electrolyte contacts the metal oxide thin film to form a photoactive site for converting light to electrical energy. The semi-transparent film reduces the internal resistance of the cell by assisting charge transfer between the metal oxide film and the electrode. Also, use of a semi-transparent film permits bi-directional irradiation of the cell to increase photoconversion efficiency.

摘要： Photoelectrochemical cell structures and methods of fabricaton are disclosed which provide for easily manufactured efficient energy conversion devices. The structures incorporate one or more chambers for the electrolyte, and utilize semiconductor photoelectrodes. In the plural chamber structure, the semiconductor may be opaque, and need not necessarily be a thin film. Specific dopants for the semiconductor provide for decreased dark current and increased open circuit voltage. Post deposition treatment is disclosed for the semiconductor to provide an increased shorting current. Increased sputtering wattage is provided to increase the short circuit current available from the cell. An electrolyte composition is described having improved performance at high light intensity.In a multi-chamber embodiment, the electrode placement causes the photoactive site to be at an end of the chamber removed from the irradiation window, thereby permitting the use of non-transparent photoelectrodes.A third embodiment is disclosed including two photoelectrodes, in combination with a properly selected electrolyte, to provide response to two different portions of the spectrum at an increase operating efficiency. A method and apparatus is disclosed for utilizing a photoelectrochemical cell of the type provided in a dual role, both for electrical conversion of impinging radiation and for heat utilization resulting therefrom.Finally, a multi-chamber, multi-electrolyte structure is disclosed providing electrical charge storage after termination of radiation.

摘要： A photogalvanic cell includes a glass substrate with a transparent electrode which receives irradiating light energy. A second electrode is positioned in spaced relationship from the first electrode and has a thin film of charge storing tungsten oxide deposited thereon. Spaced from both the transparent electrode and the tungsten oxide thin film is a counterelectrode. An electrolyte having TiO.sub.2 powder mixed therein forms a photoactive site at the surface of the transparent electrode. By physically separating the tungsten oxide thin film from the transparent electrode, more light irradiates the TiO.sub.2 thereby increasing the photoconversion of the cell.

摘要： A photogalvanic cell has a glass substrate through which irradiating light passes. A light transparent conductive thin film serves as an electrode, the film being deposited upon the glass substrate. Another layer is an electrolyte and includes an aqueous medium having TiO.sub.2 suspended therein, the TiO.sub.2 forming photoactive sites with the remaining ingredients of the electrolyte. The electrolyte layer further includes N-methylphenazine methosulfate dye which has photoconversion and electrical storage properties. During irradiation the cell may drive a load, or stored energy resulting from irradiation may drive a load after the source of irradiation is removed.

摘要： A variable transmittance double pane window includes an electrochromic material that has been deposited on one pane of the window in conjunction with an array of photovoltaic cells deposited along an edge of the pane to produce the required electric power necessary to vary the effective transmittance of the window. A battery is placed in a parallel fashion to the array of photovoltaic cells to allow the user the ability to manually override the system when a desired transmittance is desired.

摘要： Electrophotographic element typically comprising in sandwiched arrangement a transition metal oxide layer and a photoconductive layer. When an electric field is applied across the element, preferably after inserting the element between a pair of electrode layers, and an optical image is projected onto the photoconductive layer, the resulting conductivity pattern in the photoconductive layer causes corresponding coloration in the transition metal oxide layer, thereby visibly recording the optical image.
