Perovskite solar cells (PSCs) have achieved excellent power conversion efficiencies; however, under direct sunlight, device temperatures can exceed ambient temperatures by more than 50 ℃, making thermal stability a critical challenge for commercialization. This review first summarizes the degradation mechanisms of PSCs induced by elevated temperatures, followed by a discussion of heat generation, with Joule heat identified as the primary contributor. Advanced thermal management strategies are then highlighted, including the use of high thermal conductivity materials, integration with thermoelectric devices, external radiative cooling layers, down-conversion approaches, and tandem structures. By systematically presenting these strategies, this review provides guidance for enhancing both the efficiency and thermal stability of PSCs, thereby supporting their pathway toward commercialization .
