Sustainable Self‐Healing of Perovskite Solar Cells Using Dendrimers as Volatile Reservoirs (Adv. Mater. 5/2026)

Self-Healing Perovskites with Dendrimers In their Research Article (DOI: 10.1002/adma.202512410), Min Jae Ko and co-workers present a dendrimer-based self-healing strategy for perovskite solar cells. The dendrimer, with its tree-like architecture and multi-functional branches, captures volatile species released during the moisture-induced decomposition of perovskite. By acting as a volatile reservoir, it enables reversible self-healing, allowing the perovskite film to restore its pristine structure through multiple degradation cycles.
