Latest Patents

Chen's latest patents focus on methods of manufacturing photoelectrochemical cells. These patents disclose structures and fabrication methods that enable the creation of efficient energy conversion devices. The designs incorporate one or more chambers for the electrolyte and utilize semiconductor photoelectrodes. In the plural chamber structure, the semiconductor may be opaque and does not necessarily need to be a thin film. Specific dopants for the semiconductor are introduced to decrease dark current and increase open circuit voltage. Additionally, post-deposition treatment is applied to enhance the shorting current. Increased sputtering wattage is utilized to boost the short circuit current available from the cell. An electrolyte composition is also described, which demonstrates improved performance at high light intensity. In a multi-chamber embodiment, the placement of the electrode allows the photoactive site to be positioned at an end of the chamber, away from the irradiation window, thus permitting the use of non-transparent photoelectrodes. Furthermore, a third embodiment includes two photoelectrodes, combined with a carefully selected electrolyte, to respond to two different portions of the spectrum, resulting in increased operating efficiency. Chen's inventions also encompass a method and apparatus for utilizing a photoelectrochemical cell for both electrical conversion of impinging radiation and heat utilization. Lastly, a multi-chamber, multi-electrolyte structure is disclosed, which provides electrical charge storage after the termination of radiation.
