Abstract
Thermal loading remains one of the key constraints limiting photovoltaic (PV) performance, particularly under high-irradiance conditions that elevate module temperatures far above ambient.This study presents a unified multiphysics framework for analyzing a crystalline silicon PV module subjected to three cooling strategies: natural air convection, forced air cooling and water cooling.A fully coupled 3D conjugate heat-transfer model was developed in COMSOL Multiphysics, with
