Toward Circularity in Perovskite Solar Cells: Strategies for Sustainable Recycling

Perovskite solar cells (PSCs) have emerged as one of the most promising photovoltaic technologies, with power conversion efficiencies rising from 3.8% in 2009 to over 27% today. Despite these advances, concerns about lead toxicity and the depletion of scarce metals underscore the urgent need for sustainable end‐of‐life management. This review critically examines recycling strategies for PSCs, highlighting the need for material recovery, the state of the art in chemical, physical, and hybrid recycling approaches, and the limitations that hinder their deployment. Current methods face challenges, including efficiency loss, high operational costs, and environmental risks associated with solvents and processing. Future directions call for the development of greener, closed‐loop recycling technologies and integrated recovery infrastructures that balance efficiency, economic viability, and ecological safety. Advancing these strategies is essential to ensuring that PSCs contribute not only to clean energy generation but also to the establishment of a genuinely sustainable, circular materials economy.
