Abstract In this study, electrical, thermal and exergy efficiencies of PVT using fins in different materials and configurations were experimentally investigated, and optimization analysis of control parameters affecting thermal and exergy efficiencies was performed. Experiments were carried out according to frequent and sparse configurations of fins made from copper, aluminum and brass materials in both monocrystal and polycrystal panels, and compared to non-fins (empty) status. Efficiency values for both frequent and sparse fin configurations have increased significantly compared to non-fins condition. Also, the ideal number of fins for each fins material according to both electrical and thermal efficiencies were investigated. The Taguchi method was used to determine the best combination of control parameters affecting thermal and exergy efficiencies. Additionally, analysis of variance (ANOVA) was carried out to determine contribution rates of control parameters affecting both efficiencies. It has been found that for all experiments, the most effective factor on both efficiencies was fins material, and then air velocity and panel temperature, respectively.

使用不同材料翅片的基于空气的 PVT 系统的实验热力学分析：通过田口法和方差分析优化控制参数

摘要 在本研究中，实验研究了使用不同材料和配置的翅片的 PVT 的电、热和火用效率，并对影响热效率和火用效率的控制参数进行了优化分析。根据单晶和多晶面板中由铜、铝和黄铜材料制成的翅片的频繁和稀疏配置进行了实验，并与非翅片（空）状态进行了比较。与非鳍条件相比，频繁和稀疏鳍配置的效率值都显着增加。此外，根据电效率和热效率，研究了每种翅片材料的理想翅片数量。田口方法用于确定影响热效率和火用效率的控制参数的最佳组合。此外，进行方差分析 (ANOVA) 以确定影响两种效率的控制参数的贡献率。已经发现，对于所有实验，对两种效率最有效的因素是散热片材料，然后分别是空气速度和面板温度。
