The rapid deployment of solar photovoltaic (PV) technology around the world brings the ineluctable problem of disposing of and recycling decommissioned solar photovoltaic modules. Recycling will become an essential sector in the value chain of the PV industry. This paper reviews the progress in silicon photovoltaic module recycling processes, from lab-scale and pilot-scale research in order to compare mechanisms, ascertain feasible approaches, recycling yields, equipment, costs, and improvement areas for different recycling processes. Trends, gaps, and outlooks are drawn to guide future R&D. Recycling processes have evolved from mass recovery to value recovery and now full recovery. Selective delamination and automated material sorting are key enablers of high recycling yield. So far, most recycling research focuses on recovering materials, however, it is equally important to explore secondary markets and end-use applications of recovered materials, especially for glass, and polymers. To implement sustainable end-of-life recycling at a large scale, technological feasibility, economic viability, and social desirability need to be addressed altogether by innovative recycling technologies.

硅光伏组件回收工艺的最新进展

太阳能光伏(PV)技术在全球范围内的快速部署带来了不可避免的退役太阳能光伏组件的处置和回收问题。回收将成为光伏产业价值链中的重要环节。本文回顾了硅光伏组件回收过程的进展,从实验室规模和中试规模的研究,以比较机制,确定可行的方法,回收产量,设备,成本和不同回收过程的改进领域。趋势、差距和前景被用来指导未来的研发。回收过程已经从大规模回收发展到价值回收,再到现在的完全回收。选择性分层和自动化材料分拣是高回收率的关键推动因素。到目前为止,大多数回收研究都集中在回收材料上,然而,探索回收材料的二级市场和最终用途应用同样重要,尤其是玻璃和聚合物。为了大规模实施可持续的报废回收,需要通过创新的回收技术来解决技术可行性、经济可行性和社会需求。
