An overview of thermophotovoltaic generation of electricity

This paper provides an overview of the developments in thermophotovoltaic (TPV) generation of electricity that have occurred during relatively recent years (from approximately 1994 to October 1998). The components considered are the semiconductor converter, the radiator, and the means of recirculation of unusable, long-wavelength photons. A short account of the functions of each of these, their mode of operation and their performance is also given. Complete systems are also considered briefly and we conclude by offering some speculation of the future of this technology.
