Thermal Management Of Highly Concentrated Photovoltaic-Thermal System Using Confined Jet Impingement And Thermoelectric Generator

The high concentration of solar light on photovoltaic cells leads to extremely high cell temperatures, which leads to decreased cell electrical efficiency.Appropriate cooling techniques need to be integrated to maintain the PV cell temperature within the permissible temperature limit.The present study focuses on the cooling of the highly-concentrated photovoltaic thermal system using a confined jet impingement cooling system and a thermoelectric generator.The proposed configuration generates electrical power from the waste heat.The thermoelectric generator is placed between the solar cell layers and the aluminium heat sink.The effect of different TEG module sizes on the power generated by the system has been studied.The total power generated by the hybrid system is maximum with a 2525 mm TEG module.The present study will be useful in the thermal management of highly concentrated photovoltaic thermal systems.
