In Situ Polymerization of Cross‐Linked Perovskite–Polymer Composites for Highly Stable and Efficient Perovskite Solar Cells (Adv. Energy Mater. 1/2024)

Perovskite Solar Cells In article number 2302743, Gill Sang Han, Hyun Suk Jung and co-workers develop highly efficient and stable perovskite solar cells (PSCs) and modules by introducing light-induced cross-linking of acrylamide monomers with non-crystalline perovskite films. This strategy effectively passivates grain boundary defects, and the perovskite film becomes hydrophobic after cross-linking, ensuring the stability of PSCs under harsh conditions.
