Abstract
In the present invention, we describe a generic interchangeable thermophotovoltaic (TPV) receiver assembly that can be incorporated in a variety of large or small TPV generators. Our TPV receiver assembly contains low bandgap TPV cells series connected along a line on a thermally conductive circuit carrier. The circuit carrier is directly bonded to a parallel cooling channel. The cooling channel also supports and cools parallel mirror elements which concentrate infrared energy efficiently to the series connected cell string. The cell interconnections are hidden under the mirror elements. The mirror elements, cooling channel, circuit carrier, and series connected cell string together form a linear TPV receiver assembly with + and - terminals on either end. Identical receiver assemblies can be packed side by side each facing an infrared emitter in a large variety of TPV generator configurations.
