A review of techniques for solar cell cooling system and increase output energy efficiency

As working temperature plays a critical role in influencing solar PV’s electrical output and efficacy, it is necessary to examine possible way for maintaining the appropriate temperature for solar panels. This research is aiming to investigate practical effects of solar PV surface temperature on output performance, in particular efficiency. The efficiency of a PV module is limited by many factors such as solar radiation, high module temperature, dust and packing factor. A combined PV/T concept was proposed to reduce the thermal stress of PV module by recovering the heat of high PV module temperature and use it for thermal applications. After that, the cooling test was conducted to find how much efficiency improvement can be achieved with the cooling condition. The aim of this review is to provide an insight into the role of techniques for cooling PV and observation to access maximum power.
