Abstract: Under the "dual carbon" goal, photovoltaic technology application is developing rapidly, and the global installation volume is growing exponentially. The lifespan of photovoltaic modules is usually 25 to 30 years. How to deal with decommissioned photovoltaic modules has gradually become a challenge in the development of new energy field. In order to achieve economic efficiency and environmental friendliness in the recycling and treatment of a large number of decommissioned photovoltaic modules, literature review and analysis were conducted on the battery types, recycling technologies, and environmental impacts of decommissioned photovoltaic modules by the software of CiteSpace. The results show that in the past 10 years, the recycling of decommissioned photovoltaic modules has still been dominated by crystalline silicon battery modules, and transformation and upgrading of the recycling technologies as well as environmental friendliness are the key to development; the processing technologies for crystalline silicon battery modules mainly include mechanical separation method, thermal treatment method, chemical dissolution method, and various combinations of multiple processes; future technological development needs to further progress in aspects such as multi-technology combining collaborative innovation, intelligent upgrading, and breakthroughs in green and low-carbon technologies.
