A research team has developed a method for recycling perovskite solar cells using non-toxic, water-based solvents.
The recycled components were used to create new perovskite solar cells with similar power conversion efficiency as those made from new materials.
Perovskite solar cells are lightweight, flexible, and have a power conversion efficiency of over 25%.
The researchers' technique can help pave the way for a sustainable perovskite solar economy, while addressing the shorter lifespan of perovskite solar cells.
