Through this work, we have studied a thermoelectric generator-based waste heat recovery system with a low response time for fast energy generation under low and high direct normal solar radiations. Under direct normal radiation of 1000 W m-2, a TEG voltage up to~3 V has been observed within a saturation time of~900 s. A large temperature gradient (15000 K/m) is produced between hot and cold ends of the TEG module under a simple application of solid-fluid convective heat exchanger. Our results show the potential of remote heating and heat transfer for TEG power generation for small scale power emergencies.
