Very High Efficiency Solar Cell (VHESC)
Abstract
The Very High Efficiency Solar Cell (VHESC) program goal was to raise the system power efficiency of a new class of solar modules to forty percent and deliver engineering prototype modules that are producible. The modules use a novel optical system that splits light from the Sun into at least two different paths corresponding to the color of the light, and concentrates the light onto photovoltaic (PV) cells that cover different segments of the solar spectrum. System power efficiency includes all factors that impact the system (module) power efficiency, such as the transmission of light through the optics as well as the individual efficiencies of the PV cells. Analysis predicted that fifty percent efficiency at the PV cell level yields a system power efficiency of at least forty percent.
