In this study, spray cooling is applied to the cooling of photovoltaic cells, and the mathematical model of a solar photovoltaic power generation system is established by considering the power consumption of the cooling system. The net output power and electrical efficiency of the system are compared under different cooling modes.
An efficient cooling system can effectively reduce the temperature and improve the power generation performance of photovoltaic cells.
The cooling methods used are described under four broad categories: passive cooling techniques, active cooling techniques, PCM cooling, and PCM with additives. Many studies made a general review of the methods of cooling PV solar cells, especially the first three methods.
The active cooling technique is considered an effective way to improve the photovoltaic performance, but it depends on an external power source, so the external power is deducted from the power produced from the PV cells, reducing the net output power produced from the PV cells.
Conclusions In conclusion, PV cooling technologies play a crucial role in maximizing the efficiency and performance of photovoltaic (PV) solar panels.
The cooling of photovoltaic thermoelectric (PV-TE) hybrid solar energy systems is one method to improve the productive life of such systems with effective solar energy utilization. This review critically analyzes the current cooling technologies' various cooling methods and scope.
