 Novel solar-powered photovoltaic/thermoelectric hybrid power sourceHassan Fathabadi Renewable Energy, 2020, vol. 146, issue C, 426-434 Abstract: A photovoltaic (PV) module converts solar radiation into electric power. Solar collectors convert directly solar heat into hot water (not electric power). A thermoelectric generator (TEG) directly converts solar heat into electric power. Thus, this study combines a PV module with some TEGs to directly convert both solar radiation and solar heat into electric power. The result is a novel solar-powered PV/thermoelectric hybrid power source. The output power of a TEG module is very small when temperature difference between its two surfaces (hot and cold) ranges below about 50C∘. As a result, TEGs cannot be used in low-grade heat harvesting applications such as solar heat harvesting. This study also solves this defect, so that, the mentioned temperature difference is raised by utilizing a two-phase closed thermosiphon (TPCT) heat pipe, a concentrator and a radiator. A prototype of the proposed PV/thermoelectric hybrid power source has been constructed, and experimental results obtained from its operation under realistic conditions are given.
