Solar energy device comprising at least one of a photovoltaic cell or a solar thermal collector having an absorption bandwidth in the infrared wavelength region of the solar spectrum; a visible light-transmitting reflector; and at least one of a graphic film or lighted display. 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.

Solar energy devices

Solar energy device () comprising at least one of a photovoltaic cell or a solar thermal collector () having an absorption bandwidth in the infrared wavelength region of the solar spectrum; a visible light-transmitting reflector (); and at least one of a graphic film or lighted display (). 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.

A fuel cell comprising a membrane electrode assembly, and an IR transmissive window for thermographic analysis of a surface of the membrane electrode assembly is described. The test fuel cell provides a method of monitoring a fuel cell, and capturing a thermographic profile of said fuel cell with an IR detector array, while simultaneously measuring the electrochemical output of the cell, including current, voltages and half cell potentials.

Fuel cell

A method of optical infrared thermography, and the use thereof in monitoring and characterizing the polymerization of the three dimensional sample is described.
