Solar energy device ( 100 ) comprising at least one of a photovoltaic cell or a solar thermal collector ( 101 ) having an absorption bandwidth in the infrared wavelength region of the solar spectrum; a visible light-transmitting reflector ( 103 ); and at least one of a graphic film or lighted display ( 105 ). The graphic film or a lighted display present is visible through the visible light-transmitting reflector. The solar energy devices can be used, for example, as a sign (e.g., an advertising sign or a traffic sign), on the side and/or roof, as well as in a window, of a building. |
