The Photovoltaic (PV) cell converts a portion of incident irradiation of visible wavelength into electricity and the remaining into heat, thereby decreasing the electrical efficiency. Hence, it is necessary to transfer the heat generated in the module by a cooling medium, thereby maintaining the operating temperature within the operating limit. This study discusses the feasibility of cooling the monocrystalline and polycrystalline modules by using rehashed edible oil (coconut oil, sesame oil, and peanut oil) with an integrated oil tank attached to the backside of the module. This study has used the environmentally friendly rehashed edible oil as a coolant, which can be used as an alternate to the toxic mineral oil. Hence, this study can prevent the consumption of reused edible oil along with the food, which causes harmful effects on human health. The rehashed edible oil flows from the storage tank through the backside of the module and is collected in another storage tank, which can be reused. Also, the performance of the monocrystalline and polycrystalline modules under different rehashed edible oil shows a significant reduction in module temperature and improvement in the efficiency of the module. The performance of the peanut oil is found to be superior in improving the performance by 14.0 % and 16.8 % on monocrystalline and polycrystalline modules respectively.

重新利用经过加工的食用油以造福社会的新替代方法 - 光伏组件的双重效益方法


光伏（PV）电池将可见波长的入射辐射的一部分转化为电能，剩余的转化为热量，从而降低了电效率。因此，需要通过冷却介质来传递模块中产生的热量，从而将工作温度维持在工作极限内。本研究讨论了通过使用重新混合的食用油（椰子油、芝麻油和花生油）以及连接到模块背面的集成油箱来冷却单晶和多晶模块的可行性。本研究使用环保的再加工食用油作为冷却剂，可作为有毒矿物油的替代品。因此，这项研究可以防止重复使用的食用油与食物一起食用，对人体健康造成有害影响。重新混匀的食用油从储罐流经模块的背面并收集在另一个储罐中，可以重复使用。此外，单晶和多晶组件在不同的重新调匀的食用油下的性能显示出组件温度的显着降低和组件效率的提高。发现花生油的性能优越，单晶和多晶组件的性能分别提高了 14.0% 和 16.8%。
