摘　　要：As a clean and efficient renewable energy source,solar energy has been rapidly applied worldwide.The growth rate of China's installed capacity ranks first in the world.However,the life span of photovoltaic(PV)modules is 25 to 30 years,and the rapid development of installed capacity indicates that a large number of PV modules will be decommissioned in the future.Therefore,the ongoing treatment of the scrapped PV waste cells in the near future requires urgent plans and countermeasures.Proper recycling and disposal of decommissioned PV modules is a practical requirement for the sustainable development of the country and industry.Crystalline silicon(c-Si)solar cells currently occupy 85%-90%of the market share,and some scholars have begun to seek the utilization pathways of the waste Si in and outside the PV industry.In this paper,the research status of the separation and recycling process of crystalline Si PV modules is reviewed,and the recycling ways of crystalline silicon are particularly focused on.In addition,the current bottlenecks in the PV recycling industry in China are analyzed and some suggestions on the sustainable development of the PV industry are proposed.
