Review of Recent Advances in Thermophotovoltaics

    Research output: Contribution to conferencePaper


    Thermophotovoltaic (TPV) generation of electricity is attracting attention because of advances in materials and devices and because of a widening appreciation of the large number of applications that may be addressed using TPV-based generators. The attractions include the wide range of fuel sources and the potentially high power density outputs. The two main approaches to TPV generators are (1)broad-band radiators, coupled with converters with bandgaps in the range 0.4-0.7 eV, and (2) narrow-band emitters coupled with lower-cost silicon converters. The key issues in realizing a viable TPV system are the durability, efficiency, and properties of the radiant emitter; the recuperation of sub-bandgap photons; the optimization of the converter performance; and the recuperation of wasteheat.
