Abstract

We present a green-solvent remanufacturing strategy for mesoscopic carbon-based perovskite solar cells (CPSCs) that enables complete recovery of the printed device stack. By immersing aged devices in γ-valerolactone (GVL), the perovskite absorber can be selectively removed without harming the underl...
