    The integration of photovoltaic-thermal (PVT) systems with advanced cooling techniques is crucial for improving energy e±ciency and overcoming performance limitations in solar energy conversion. This study investigates the combined e®ects of solar thermal radiation, Cattaneo{ Christov non-Fourier heat transport and magnetohydrodynamic (MHD) rotating °ow on PVT cooling performance. The purpose is to provide a deeper understanding of how thermal and electromagnetic interactions in°uence heat transfer and system e±ciency, particularly under conditions where conventional Fourier-based models fall short. A carboxymethylcellulose (CMC){water-based base °uid enhanced with nanoparticles zirconium oxide (ZrO2), copper (Cu) and aluminum oxide (Al2O3) is employed as the working medium to further boost thermal conductivity and system e±ciency. A mathematical model is developed to capture the dynamics of radiative heat °ux, magnetic ¯eld, rotation and nonlinear thermal relaxation e®ects. The governing equations are transformed into dimensionless form and solved numerically using a Chebyshev collocation method. The results demonstrate that the inclusion of ZrO2, Cu and Al2O3 nanoparticles in the CMC{water base °uid signi¯cantly improves thermal conductivity, thereby enhancing the system's cooling capacity. Under solar thermal radiation, ternary hybrid nano°uids demonstrate approximately 20% superior thermal regulation. The novelty of this work lies in the synergistic analysis of MHD rotating °ow, Cattaneo{Christov heat transport and nanoparticleengineered CMC-based °uids for PVT cooling, providing new physical insights and practical guidelines for the design of high-performance renewable energy systems.
