Experimental Investigation of Photovoltaic–Thermoelectric Generator (PV-TEG) Integrated Hybrid System Performance

A coupling of photovoltaic (PV) and thermoelectric generator (TEG), called the photovoltaic-thermoelectric (PV-TEG) hybrid system, is a promised technique to influentially make wider the utilize of solar radiation that falling on the upper surface of the PV and harvesting the wasted heat in the PV via the TEG module to increase the total output power and boosted (PV-TEG) system comprehensive performance. The combination of photovoltaic and thermoelectric apparatus demands specific interest since the solar cell with the thermoelectric device own an inverse relation with temperature. Therefore, the research study was been experimental. Firstly, the optimum design of (PV-TEG) hybrid system performance was tested experimentally in the indoor environment inside the Graduate Studies Laboratory of the College of Engineering, University of Kerbala to validate the correctness of the chosen system. Secondly, The (PV-TEG) performance was emulate with the solar cell system alone and the photovoltaic/ thermal system performance. The results appeared that the PV- 50 items of TEG as model of hybrid system generated an electrical power was higher by (31.66 % and 16.5 %) compared with that of the traditional photovoltaic only and the PV/T system experimental under the same operating conditions. The electrical output power (Eel ) and electrical efficiency ( ηel ) of the PV-TEG hybrid system were higher than that of the PV module and PV/T system in all tests. The Eel is about (20.21) W and ηel is about 5.83 % in experimental tests.
