A robust shield emerges on perovskite, crafted through the dance of nucleophilic addition, coordination, and polymerization with triphenylmethane triisocyanate. A high-melting-point organic promoter for air-doping bars ion diffusion in the transport layer. This duet yields >25 % efficient n-i-p perovskite solar cells, basking in operational stability at 65 °C.
