Abstrakt: A thermodynamical consideration of a selective wavelength emitter for thermophotovoltaic energy generation is presented to express emitter emission properties through spectroscopic parameters of dopant atoms. It is found the heat-light conversion can produce nonequilibrium conditions in the emitter material due to radiative cooling of the atomic excited states. A possible influence of inter- and intra-atomic energy transitions to emitter parameters is discussed. © 1996 American Institute of Physics. [ABSTRACT FROM AUTHOR]
