退役光伏组件回收技术研究进展
Research progress on recycling technology of decommissioned photovoltaic module
摘要
Abstract
The disposal and recycling of decommissioned PV modules have become imperative with the expansion of photovoltaic(PV)installed capacity and the phased decommissioning of early PV modules in recent years.Its recycling technology has become a key issue in the field of sustainable energy.This study reviewed the types and structures of retired photovoltaic modules,the principles,processes,and advantages/disadvantages of recycling methods,which include physical,chemical,pyrolysis,biological,hybrid,and novel approaches.The research progress of silicon recovery,metal recovery,and comprehensive recovery of valuable components for decommissioned crystalline silicon PV modules was discussed.An in-depth analysis of the core technological advancements in recovering valuable components from thin-film PV modules via pyrometallurgical processes,hydrometallurgical processes,biological methods and emerging technologies was conducted.It was found that traditional methods such as physical,chemical,and pyrolysis approaches remain the mainstream for PV recycling,which however have the risk of high energy consumption,severe pollution,and substantial chemical usage.Meanwhile,biological methods and green leaching are poised to become key in the green recycling of PV modules,which are of low technological maturity and high costs.Finally,the study summarized domestic and international policies on PV recycling,identifies existing technical challenges,and outlines future development of PV recycling technologies.These insights hold critical implications for guiding the sustained,large-scale,and environmentally friendly growth of the PV industry.关键词
