How to recycle methylammonium lead iodide from perovskite solar cells

A German research team has developed a new technique to recover and reuse methylammonium lead iodide (MAPbI3) from perovskite solar cells via solvent extraction. Such recycling method can reportedly save up to 61% costs in the lab and industrial manufacturing. A German research team at Helmholtz Institute Erlangen-Nürnberg for Renewable Energy, Jülich Institute for Energy, has reported success with the recovery of every layer of a planar methylammonium lead iodide (MAPbI3) perovskite solar cell using a layer-by-layer solvent extraction approach, followed by purification to restore quality. "This ...
