光伏废弃物的研究进展、热点与未来展望

Abstract With the rapid growth of photovoltaic installed capacity, the recycling of photovoltaic waste has become an increasingly prominent issue, necessitating a systematic review and comprehensive evaluation of related studies. This study combines quantitative analysis with critical review to systematically examine 293 English-language publications on the topic of “photovoltaic waste” from the Web of Science Core Collection. First, visual analyses of national distribution, co-citation networks, keyword co-occurrence, and emerging research hotspots are conducted using CiteSpace software. Then, a critical review is carried out focusing on three key areas: forecasting of photovoltaic waste generation, assessment of environmental benefits, and analysis of economic performance. The results show that photovoltaic waste has emerged as a current research hotspot, with the number of related publications growing exponentially. China, Australia, India, the United States, Italy, South Korea, and Germany are the major contributing countries, and a preliminary transnational collaboration network has taken shape. Existing studies are predominantly technology-oriented, with research themes showing a phased transition from technological development to life cycle assessment and sustainable management. Future research should focus more on the scientific forecasting of photovoltaic decommissioning waves and the design of efficient recycling systems. Finally, based on industrial development trends, this paper provides an outlook on future research directions from the perspectives of international cooperation, life-cycle thinking, and policy mechanisms.
