We are pleased to announce the publication of a new research paper presenting a 3D simulation model for an optical photovoltaic power converter hybridized with a thermoelectric generator, demonstrating its immense potential for applications in extremely low temperature environments.
In this study, an innovative methodology was employed to design the hybrid converter, optimizing the height of the thermoelectric couple under various air temperature conditions. The design encompasses two distinct thermoelectric device scenarios: a low ZT (~1) and a high ZT (~2.4). Moreover, a state-of-the-art power converter featuring a multijunction vertical structure composed of GaAs was taken into account.
The simulation results unveiled remarkable efficiency improvements. At 200 K of air temperature and high ZT, the hybrid power converter exhibited maximum relative efficiency enhancement factors of 6.16% (temperature matched) and a staggering 48.71% (temperature mismatched) when compared to a nonhybrid power converter. These findings pave the way for the development of an entirely new generation of highly efficient hybrid converters.
The article is now available for early access in the IEEE Xplore database.
