الوصف: We formulate a simple model for the power densities generated by thermoradiative devices based on narrow-gap semiconductors. Our model is more realistic than previous treatments because it includes the effects of both Auger (impact ionization) and Shockley–Read–Hall (SRH) processes on the generated power. For known materials and based on optimal values for the energy gap and operating bias, maximum possible power densities are estimated in the presence of strong nonradiative processes. In particular, we derive best-case numerical projections for thermoradiative devices based on III-V type-II superlattices and bulk HgCdTe operating at practical temperatures and having a range of SRH lifetimes. Devices with strong Auger suppression and configured in nonplanar architectures with limited geometric fill factor can in principle attain power densities per unit active area approaching 10 W/m2. However, practical limitations will more likely constrain the generation density to
