Abstract Photovoltaic-thermal (PVT) systems offer transformative potential for renewable energy generation, yet their commercial adoption faces critical unresolved challenges. This review synthesizes experimental studies to address three key gaps: fragmented validation of hybrid cooling technologies (nanofluids, PCMs, heat pipes), inconsistent reporting of scalability challenges like material degradation, and the absence of standardized protocols bridging lab-scale and industrial performance. While advanced cooling demonstrates efficiency gains in controlled environments, most studies focus on small scale setups under idealized conditions, with limited examination of real world durability or commercial deployment. Our analysis reveals persistent barriers including PCM leakage, nanofluid sedimentation, and water system freeze damage. Hybrid designs combining heat pipes with PCMs emerge as particularly promising, exhibiting lower degradation than conventional systems. The review concludes by proposing actionable solutions, accelerated aging tests and modular scaling protocols, to translate laboratory innovations into robust, field ready PVT technologies.
