Abstract:
Molecular press annealing enabled decylamine iodide to form a surface-confined 2D (n = 2)/3D heterojunction. The compact overlayer suppressed non-radiative recombination to deliver 25.55% PCE, while its hydrophobic long alkyl chains suppressed moisture ingress and improved device stability.
