摘　　要：Solar energy is currently one of the most promising clean energy sources and the use of solar energy has led to a rapid increase in the number of solar cells.As one of the fastest-growing electronic wastes,the resource treatment of solar cells at the end of their life should not be neglected.This review discusses the trend for the market development of crystalline-silicon solar cells and analyzes their physical structure and composition.It also discusses the current domestic and international recycling technologies for crystalline-silicon solar cells,including manual dismantling,inorganic acid dissolution,the combination of heat-treatment and chemical methods,and organic solvent dissolution.The shortcomings of the above treatment methods are discussed and some views on the recycling of waste crystalline-silicon solar cells are presented.Constructive suggestions for the green and sustainable development of crystalline-silicon solar cells are put forward by comparing different treatment-recycling processes.
