BouzidN. Maamri<p class="Els-Affiliation">In this paper,we investigated the heat to electricity conversion efficiency of In<sub>1-x</sub>Ga<sub>x</sub>As<sub>y</sub>Sb<sub>1-y</sub>radioisotope thermophotovoltaic (RTPV) converter with x=0.8 and y=0.18, taking account of the photons with energy below the cells bandgap using a comprehensive analytical process. This was done with a computer program designed for this reason, which allowed the computation of the cell performance under a variety of specified incident radiation spectra as well as a variety of material parameters. The results show that for an emissivity value of 0.78, a cell thickness of about 7µm with low front recombination velocity(700cm/s),a conversion efficiency greater than 29% can be obtained for radiator’s temperature of1300°k at ambient temperature. This efficiency will decrease as the cell temperature increase.</p>http://jfas.info/index.php/jfas/article/view/96Radioisotope,Emissivity,Recombination velocity, Efficiency, Temperature
