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。 |

Abstract: |
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. |
