摘要
在“双碳”大背景下,光伏产业成为了国家重点发展行业。但是在利用金刚线切割技术生产太阳能电池的核心原料--晶硅片时,会产生大量的切割废料,即金刚线切割废料。金刚线切割废料是一种富含纯硅的亚微米级薄片状物质,如果不加以利用,会造成环境污染和资源浪费,因此该废料的回收利用成为当下研究的热点。目前,金刚线切割废料的回收利用方式主要为制备纯硅、陶瓷材料、电极材料和硅基合金。除此之外,还有利用金刚线切割废料制备析氢产氢材料、吸附剂材料、金属捕收剂等回收方式。本综述首先阐述了金刚线切割废料的物化特性,然后对其回收利用的研究展开了详细介绍,最后对其回收利用的技术做出了总结和展望,为光伏产业中金刚线切割废料的回收利用提供了一定的参考和启示。
In the context of the"Carbon Peaking and Carbon Neutrality"strategy,the photovoltaic industry has become a key industry in China.However,when utilizing diamond-wire sawing method to produce crystalline silicon wafers(the raw material for solar cells),the slicing process produced a large amount of sawing waste,i.e.diamond-wire sawing silicon waste(DWSSW).DWSSW is in the form of submicron flakes rich in pure silicon.If not utilized,this waste can pose a significant environmental hazard and resource wastage,making its recycling a current focus of research.Currently,the recycling and utilization of DWSSW primarily involves the preparation of pure silicon,ceramic materials,electrode materials,and silicon-based alloys.In addition,there are some non-mainstream studies,such as the preparation of hydrogen evolution materials,adsorbents,and metal collectors.In this review,the physical and chemical characteristics of DWSSW were firstly introduced,followed by a detailed analysis of the studies on its recycling and utilization.Finally,a summary and outlook on the studies were proposed,providing insights and references for the recycling and utilization of DWSSW in photovoltaic industry.
