A solar co-generator for producing both heat energy and electricity is disclosed. A solar concentrator directs sunlight into a container lined with solar cells and filled with a thermal transfer fluid. The fluid is transparent with respect to certain wavelengths of light that may be converted to electricity by the solar cell, but is opaque with respect to longer wavelengths, particular the infrared band. The infrared portion of the sunlight heats the thermal transfer fluid, which then transfer that heat through a storage facility using a heat exchange mechanism. The thermal transfer fluid increases the efficiency of photovoltaic generation by preventing heating of the solar cells due to infrared radiation. The thermal transfer fluid may be a mixture containing barium sulfate and a suspension of zinc sulfide phosphors. A fluorescing anti-reflective coating may be applied to the solar cells to further increase efficiency.
