Photovoltaics thermal (PV/T) management has attracted much attention in research, with a particular focus on improving its performance in the current globalized market. As the continuous elevation of PV surface temperature due to direct sun rays degrades PV/T performance, effective cooling of PV panels has been identified as a way of improving efficiency. Thermal regulation strategies have suggested that water, nanofluids, air, phase change materials (PCM), and nano-enhanced PCMs can be varied for cooling purposes. The current study considers silica and carbon black nanoparticles dispersed in phase change materials for two purposes: firstly, to increase the speed of storing and releasing thermal energy of nano-enhanced PCM; and secondly, for improving the thermal conductivity of PCM. The experimentation of this study was conducted in outdoor conditions of Taxila, Pakistan during the month of March 2020. To construct the nano-enhanced PCM, Silica (SiO₂) and Carbon Black (CB) NPs were added to PT-58 at concentrations of 0.25 wt $\%$ and 0.5 wt $\%$. NPs at 0.5 wt $\%$ concentration in CB/PT-58 as a nano-enhanced PCM showed the topmost performance in cooling of a PV panel. The experimentation depicted a maximum decrease in temperature of the system using CB/PT-58 and SiO₂/PT-58, at approximately 9.74 $°C$ and 8.92 $°C$ respectively, where the electrical efficiency of the systems improved to 12.07% and 12.00% respectively, at a concentration of 0.5 wt $\%$. The maximum percentage increment in electrical power was 30.45 $\%$ and 30.23 $\%$ respectively, in the case of CB/PT-58 and silica/PT-58 nano-PCM at 0.5 wt $\%$ of NPs in base PCM. The results elucidate that the performance of the system using the CB/PT-58 nano-PCM as a cooling method was higher than the silica/PT-58 nano-PCM.

光伏热 (PV/T) 管理在研究中引起了广泛关注，特别侧重于提高其在当前全球化市场中的性能。由于阳光直射导致 PV 表面温度持续升高会降低 PV/T 性能，因此有效冷却PV 面板已被确定为提高效率的一种方式。热调节策略表明，水、纳米流体、空气、相变材料(PCM) 和纳米增强型 PCM 可以因冷却目的而变化。目前的研究将二氧化硅和炭黑纳米颗粒分散在相变材料中有两个目的：首先，提高纳米增强相变材料储存和释放热能的速度；其次，为了提高PCM的热导率。本研究的实验于 2020 年 3 月在巴基斯坦塔克西拉的室外条件下进行。为了构建纳米增强型 PCM，将二氧化硅 (SiO 2 ) 和炭黑 ( _CB ) NP 添加到 PT-58 中，浓度为0.25 重量$\%$和 0.5 重量$\%$. 0.5 wt 的 NP$\%$CB/PT-58 中的浓度作为纳米增强型 PCM 在光伏面板的冷却方面表现出最高的性能。_{实验描述了使用 CB/PT-58 和 SiO 2} /PT-58的系统的最大降温，约为 9.74$摄氏度$和 8.92$摄氏度$浓度为 0.5 wt 时，系统的电效率分别提高到 12.07% 和 12.00%$\%$. 电力的最大百分比增量为 30.45$\%$和 30.23$\%$分别在 CB/PT-58 和二氧化硅/PT-58 纳米 PCM 的情况下为 0.5 wt$\%$基础 PCM 中的 NPs。结果表明，使用 CB/PT-58 纳米 PCM 作为冷却方法的系统性能高于二氧化硅/PT-58 纳米 PCM。
