Abstract
In order to design improved TPV generators, it is important to characterize the performances of the key components. While it is possible to project high cell electric power densities and conversion efficiencies using measured cell quantum efficiency, filter spectra, and emitter spectra, it is important to confirm these projections with actual measurements of cell electric power and conversion efficiency. It is possible to both measure the spectral properties of TPV spectral control components and to document the radiation to electric conversion efficiency for single cell assemblies by using the “FlatPack” test unit described here. For a SiC emitter temperature of 1450 °C, a cell electric power density of 2.5 W/cm2 was measured using the FlatPack test unit. The measured radiation heat load was 15.2 W/cm2 resulting in a radiation conversion efficiency of 16.4%.
