Photovoltaic (PV) technology has evolved as the major renewable power resource in the worldwide green energy sector to meet the future challenge of energy needs. The main barrier for the commercialization of this technology which is even estimated to contribute about 20% of the global energy supply by 2050 is the poor performance and stability of the PV modules in the outdoor climate. Encapsulation of PV modules is one among the multiple ways to mitigate these stability issues and it plays an important role in the enhancement of the device lifetime by providing a barrier structure to restrict the penetration of oxygen and moisture. This review summarizes the extensive progress made in the field of polymer encapsulate materials for PV modules and also providing current challenges and future perspectives in this area.

光伏 (PV) 技术已发展成为全球绿色能源领域的主要可再生能源，以满足未来能源需求的挑战。这项技术商业化的主要障碍是光伏组件在室外气候下的性能和稳定性不佳，据估计，该技术到 2050 年将贡献全球约 20% 的能源供应。PV 模块的封装是缓解这些稳定性问题的多种方法之一，它通过提供屏障结构来限制氧气和水分的渗透，在提高器件寿命方面发挥着重要作用。本综述总结了光伏组件聚合物封装材料领域取得的广泛进展，并提供了该领域当前的挑战和未来前景。
