Thermal Management Technologies for Improving the Thermal Stability of Perovskite Solar Cells

Abstract

Joule heating is the dominant cause of elevated device temperature in perovskite solar cells (PSCs) under operation, significantly degrades their long-term thermal stability. High temperatures degrade PSCs primarily through accelerated material decomposition and interfacial reactions, posing a major barrier to commercialization. Key thermal management strategies, such as integrating thermally conductive materials, radiative cooling layers, and tandem structures, effectively suppress heat accumulation and enhance device durability.
