Experimental Study on Photovoltaic-Thermoelectric Hybrid Power Generation System
In order to improve the efficiency of photovoltaic-thermoelectric(PV-TE)hybrid power generation system,and to find an engineering suitable cooling method combined with thermoelectric(TE)module,an experimental system including solar simulator,photovoltaic power generation module and TE module is built,and the PV-TE hybrid power generation system is tested and studied.The output power of PV-TE hybrid power generation system,the cold end temperature,the temperature difference between cold and hot ends and the output power of TE module are studied and analyzed by different cooling methods.The experimental results show that after installing the TE device on the photovoltaic panel,the photovoltaic cell exhibits different performance when the TE device is in two different states:open circuit and closed circuit.Installing heat dissipation aluminum fins has a significant cooling effect.The cold end temperature of the TE device decreases by about 5 K,and the temperature difference between the cold and hot ends increases,resulting in an increase in output power.Combining heat pipes on the basis of cooling aluminum plates further enhances the cooling effect.
