Abstract: The use of photovoltaic (PV) cells to convert solar energy to electricity is becoming increasingly prevalent; however, there are still significant limitations associated with the widespread adoption of PV cells for electricity needs. There is a clear need for a high efficiency solar power system that supplies electricity at a competitive cost and that provides for an on-demand supply of electricity as well as energy storage. By combining aspects of concentrated solar power and concentrated photovoltaics, the present invention provides a device that enables the conversion of sunlight to electricity at very high efficiencies and that enables the transmission of thermal energy to heat storage devices for later use. The disclosed device enables transmissive CPV through the use of a multijunction PV cell mounted on a transparent base. The use of a multijunction cell allows for highly efficient absorption of light above the bandgap of the lowest bandgap subcell. The transparent base permits transmission of a high percentage of the remaining light below the bandgap of the lowest bandgap subcell. The present invention also discloses a method of generating electricity through the use of a transmissive CPV device. Sunlight is concentrated onto one or more surfaces of the device. High energy light is absorbed by a multijunction PV cell and converted directly to electricity, while low energy light is transmitted through the device into a thermal storage device, which may then be coupled to a heat engine to generate dispatchable electricity.

Abstract: Embodiments of the present invention may utilize one or more techniques, alone or in combination, to maximize a surface area of a receiver that is configured to convert light into another form of energy. One technique enhances collection efficiency by controlling a size, shape, and/or position of a cell relative to an expected illumination profile under various conditions. Another technique positions non-active elements (such as electrical contacts and/or interconnects) on surfaces likely to be shaded from incident light by other elements of the receiver. Another technique utilizes embodiments of interconnect structures occupying a small footprint. According to certain embodiments, the receiver may be cooled by exposure to a fluid such as water or air.
