Abstract: The accelerated global transition toward renewable energy structures has precipitated a surge in photovoltaic module installations, intensifying environmental governance pressures associated with decommissioned crystalline silicon modules. This review systematically examines resource recovery technology systems and policy pathways for end-of-life crystalline silicon photovoltaic modules, with a focused emphasis on the efficient reclamation of valuable metals and the construction of circular economy models. By analyzing the energy efficiency of three main recycling technologies—mechanical, thermal, and chemical treatment, this work reveals their economic and technical limits. Mechanical processes, like high-voltage pulse crushing, can concentrate metals, but their efficiency is constrained by material separation rates. Thermal treatment (400~600℃) can recover high-purity materials (glass purity>98.5%), but it faces challenges of high energy consumption and the treatment of fluorine-containing exhaust gases. Chemical treatment (e.g., using a toluene solvent system) offers significant advantages in achieving high purity (>99%) in silicon wafer recycling, but it poses risks of secondary pollution and cost concerns. This work also explores the recovery of valuable metals from end-of-life crystalline silicon photovoltaic modules, outlining the challenges and prospects in this area.

摘要： 随着全球能源结构向可再生能源加速转型，光伏组件装机量激增导致退役晶硅组件的环境治理压力日益凸显。本文系统论述了退役晶硅光伏组件的资源化回收技术体系及政策路径，重点聚焦有价金属的高效回收与循环经济模式构建。通过分析机械处理、热处理及化学处理三类主流技术的能效特征，揭示了其技术经济性边界：机械处理(如高压脉冲破碎技术)可实现金属定向富集，但受限于材料解离效率；热处理(400~600℃)虽能实现高纯度材料回收(玻璃纯度>98.5%)，却面临能耗高与含氟废气治理难题；化学处理(如甲苯溶剂体系)在硅片回收纯度(>99%)方面优势显著，但存在二次污染风险与成本问题。此外，本工作还对退役晶硅光伏组件中的有价金属回收技术进行了分析，指出回收退役晶硅光伏组件的研究前景和所面临的挑战。
