Sustainable decommissioning of perovskite solar cells: from waste to resources

Perovskite solar cells (PSCs) have witnessed a rapid progression as emerging alternatives for innovative photovoltaics (PVs). However, this promising growth also comes with challenges related to the end-of-life (EoL) management of exhausted devices. In this review, we discuss different studies on the implications of the decommissioning of PSCs from a sustainable perspective by reviewing current PSC recycling strategies as general guidelines in the field of EoL PSCs. We hope that this review would encourage the necessary development of more virtuous energy-efficient and environmentally friendly recycling protocols for PSC recovery, from lab- to large-scale application in view of perovskite-based PV technology's imminent jump to the market.
