摘要

本研究旨在提高热性能，并比较两种常见晶体光伏电池板（单晶和多晶）的性能。使用 SolidWorks 和 ANSYS-Fluent-2021-R2 对带有后冷却系统的模块进行了设计和数值分析，以模拟巴格达正午天气。所使用的冷却系统包括厚度为 5 厘米的相变材料石蜡（RT55）和带有 33 片翅片的散热器，翅片高度为 10、20 和 30 毫米，厚度为 2、4 和 6 毫米。结果表明，对于多晶体，使用 PCM 可使面板温度降低 8.4°C，使用 PCM 散热片可使面板温度降低 11.9°C。此外，输出功率提高了 10.2 瓦，达到 200.6 瓦，效率提高了 5%。同样，使用 PCM 和 PCM-fins，单晶的温度分别降低了 8.3°C 和 12.5°C。因此，输出功率在 202.4 W 的基础上提高了 10.7 W，电气效率提高了 5.2%。研究结果表明，单晶硅的性能优于多晶硅。这一结果是可以接受的，并且与之前的研究结果十分吻合。

دراسة أداء النماذج الكهروضوئية مع نظام تبريد السطح الخلفي

This research aims to improve thermal performance and compare the performance of two common crystalline PV panel types (Mono and poly). Modules with a back-cooling system were designed and numerically analyzed with SolidWorks and ANSYS-Fluent-2021-R2 for the simulation under Baghdad weather at noon. The cooling system used consists of a phase-change material, paraffin wax (RT55), with a thickness of 5 cm and a heatsink with 33 fins with heights of 10, 20, and 30 mm and thicknesses of 2, 4, and 6 mm. to select the best height of the wax 1, 3, 5, 10, 20 cm examined. The result showed that for polycrystals, the panel temperature was reduced by 8.4°C using PCM and 11.9°C using PCM-fins. Also, output power was enhanced to 200.6 W by 10.2 W, and efficiency improved by 5%. Similarly, using PCM and PCM-fins lowered the temperature of the monocrystalline by 8.3 and 12.5°C, respectively. Therefore, the output power is enhanced to 202.4 W by 10.7 W and improves the electrical efficiency by 5.2%. The results of the study showed that mono had better performance than poly. This result is acceptable and is in good agreement with previous studies.
