    Patent number: 7541537
    Abstract: The present invention is a photovoltaic cell having improved conversion properties. The cell includes a cover for a photovoltaic device. In one embodiment, the cover includes a fluorescent material that shifts the wavelength of some of the incident light to be closer to the wavelength that produces the least amount of thermal loading on the photovoltaic device. In another embodiment, the cover includes a fluorescent material between two reflective filters. The cell and cover may either be placed together in a stack or separated from one another.
