Long-term stability in γ-CsPbI3 perovskite via an ultraviolet-curable polymer network
Abstract
γ-phase CsPbI3 perovskites are attractive for solar cells, but suffer from environmental degradation. Here, the addition of an ultraviolet-curable polymer network improves structural and electrical stability, retaining 90% of its electrical properties after exposure to air for 35 days.
