Abstract

Passive thermal management of photovoltaic (PV) panels is an effective and low-cost method for reducing the surface temperature and improving the power output of these systems. In the current study, it is aimed to upgrade the efficiency of a PV system using a latent heat storage system with metallic mesh layers and multi-metal spinel oxide nanoparticles. The experimental part of this work contains two stages. In the first stage, three PV systems including an unmodified PV, LHSS (only paraffin)-integrated PV system and a LHSS-integrated PV system that modified with metallic mesh layers. As a result of the initial test, the PV system with mesh layers added LHSS gave the best performance results. In the second experiment, the mesh integrated LHSS of the PV system has been modified with MgOAl2O3 nanoparticles for enhanced thermal conductivity and compared with the PV system with mesh layer integrated LHSS containing only paraffin. According to the experimental results of this work, applying different types of LHSS configurations significantly reduced the surface temperature of the PV panel. The overall outcomes of the present work showed that using a LHSS with MgOAl2O3 nanoparticles-doped paraffin and metallic mesh layers upgraded the normalized power output efficiency and performance ratio of the unmodified system as 17.43% and 15.72%, respectively.

利用带有金属网层和多金属尖晶石氧化物纳米颗粒的潜热储存系统对光伏组件进行无源热管理

光伏（PV）电池板的被动热管理是降低表面温度和提高这些系统功率输出的一种有效而低成本的方法。在当前的研究中，目的是利用带有金属网层和多金属尖晶石氧化物纳米颗粒的潜热存储系统来提高光伏系统的效率。这项工作的实验部分包括两个阶段。第一阶段是三个光伏系统，包括未改良的光伏系统、集成了 LHSS（仅石蜡）的光伏系统和集成了金属网层的 LHSS 光伏系统。初步测试结果显示，添加了 LHSS 的网状层的光伏系统性能最佳。在第二次实验中，光伏系统的网状集成 LHSS 被添加了 MgOAl2O3 纳米粒子以增强导热性，并与仅含有石蜡的网状层集成 LHSS 的光伏系统进行了比较。根据这项工作的实验结果，应用不同类型的 LHSS 配置可显著降低光伏板的表面温度。本研究的总体结果表明，使用掺有 MgOAl2O3 纳米颗粒的石蜡层和金属网状层的 LHSS，与未改良系统相比，归一化功率输出效率和性能比分别提高了 17.43% 和 15.72%。
