ABSTRACT
Sun-based energy is accessible and bottomless in nature, and it is simple to gather it by utilizing sun-powered photovoltaic (PV) cells that convert sun-based energy to electrical energy. Normally, a PV cell changes over approximately 5%–18% of the incident sunlight into power, and so as to keep up the energy balance, approximately 60% of the radiation is changed to heat energy. Mounting temperature blocks the electrical effectiveness of PV frameworks. A pragmatic method for increasing the yield proficiency of solar PV cell is to diminish the working temperature. This study exhibits the different techniques used by various researchers for cooling of the solar PV system through nanofluids. The impact of components (e.g., size of the nanoparticle, the concentration of nanoliquid, stream rate of nanofluid, and geometry of channel containing nanofluid) affecting the effectiveness of PV frameworks has been discussed. Aggregate outcomes of various analysts demonstrate that the proficiency of the PV frameworks (utilizing the nanofluid as a coolant) increment with the expanding stream rate. The productivity of these frameworks enhances with increasing nanofluid concentration until the agglomeration/clustering of nanoparticles do not occur. Relating to the latest examinations, nanoparticle stability is the major uncertain issue, preventing the business-scale use of nanofluids for the cooling of PV modules. In the end, the environmental and financial preferences of these frameworks are exhibited.
