20.500.12556/RUL-167799 Unraveling temperature distribution within crystalline silicon PV modules by different finite element method-based thermal modeling approaches In this work, the steady-state spatial temperature distribution in commercial high-efficiency crystalline silicon PV modules is studied using different FEM-based thermal models that encompass conductive, convective, and radiative heat transfer mechanisms. The results show that the lateral temperature distribution within the PV module depends on the module inclination angle and may be highly inhomogeneous, with a temperature difference of ≈5 °C between its warmest and coolest solar cells. Furthermore, It is demonstrated that wind plays a crucial role in determining the operating temperature of PV devices. Specifically, it is shown that forced convection has an even more significant positive effect at higher wind speeds and larger PV module dimensions since the transformation of laminar to turbulent wind contributes to additional cooling. Finally, the power losses associated with the lateral temperature variations across the PV module are analyzed. The results show that the effect of temperature inhomogeneity plays a negligible role in the performance of standard single-junction silicon PV modules due to a very small temperature coefficient of the solar cell short-circuit current. crystalline silicon PV modules FEM-based thermal modeling heat transfer mechanisms temperature distribution temperature inhomogeneity-induced PV module power loss kristalnosilicijevi PV moduli termično modeliranje na osnovi metode končnih elementov mehanizmi prenosa toplote temperaturna porazdelitev izguba moči PV modula zaradi temperaturne nehomogenosti true false true Angleški jezik Slovenski jezik Članek v reviji 2025-03-12 14:21:03 2025-03-12 14:21:10 2025-03-13 04:15:53 0000-00-00 00:00:00 2025 0 0 11 str. iss. 3, art. 2401026 Vol. 8 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.383.51 2513-0390 10.1002/adts.202401026 220284931 Advcd_Theory_and_Sims_-_2024_-_Tomsic_-_Unraveling_Temperature_Distribution_Within_Crystalline_Silicon_PV_Modules_by.pdf Advcd_Theory_and_Sims_-_2024_-_Tomsic_-_Unraveling_Temperature_Distribution_Within_Crystalline_Silicon_PV_Modules_by.pdf 1 D8081069727B3287E15495A3D3910F65 f7a4d53e0347f49247ed9f1f3462a1d11405af13932f4fa6e2a4307784a5d8ec 2cd39bf0-ff44-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200578 https://onlinelibrary.wiley.com/doi/10.1002/adts.202401026 1 e3211f1b-ff43-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200576 Fakulteta za elektrotehniko 0 0 0
