Solar energy devices

A solar energy device comprising:

• at least one of a photovoltaic cell or a solar thermal collector having an absorption bandwidth that includes at least a portion of the near infrared wavelength region of the solar spectrum;
• a visible light-transmitting reflector having first and second generally opposed major surfaces, the visible light-transmitting reflector positioned to reflect light from the first major surface onto the at least one of a photovoltaic cell or a solar thermal collector, the visible light-transmitting reflector comprising a multilayer optical film having an optical stack comprising a plurality of alternating first and second optical layers with different indices of refraction, wherein the multilayer optical film reflects at least a portion of light in a range of wavelengths that corresponds with the absorption bandwidth of the at least one of a photovoltaic cell or a solar thermal collector;
• and
• at least one graphic film positioned closer to the second major surface of the visible light-transmitting reflector than to the first major surface of the visible light-transmitting reflector, wherein the graphic film is visible through the visible light-transmitting reflector and includes at least one of a pattern or image.
