Abstract Tin (Sn)‐based perovskite solar cells (PSCs) are extremely vulnerable to oxygen. Nevertheless, mechanism understanding and fundamental strategies achieve oxygen‐stable Sn‐based PSCs lacking. Here a nucleation‐layer assisted (NLA) strategy by forming nucleation layer at the interface of hole transport attain highly quasi‐2D Ruddlesden‐Popper (RP) is reported. The formation process consists washing off prepared film annealing residue on substrate, which produces new substrate for fabrication. Such can transform subsequently deposited from small‐n‐value dominated wide phase distribution with random crystal orientation into an intermediate‐n‐value narrow vertical orientation. This also improves morphology coadjacent flake‐like grains, leading reduced grain boundaries pinholes. resultant NLA shows more efficient carrier capability, lower exciton‐binding energy, weakened electron‐phonon coupling, significantly decreased oxygen diffusion rate upon exposure. Consequently, RP PSC champion efficiency 11.18% obtained. unencapsulated device preserves 95% its initial after 2700‐h aging test, creating record stability PSCs.

Tin halide perovskite solar cells (THPSCs) are an eco-friendly alternative to lead cells. However, defect formation hinders their commercialization. Specifically, the oxidation of Sn2+ Sn4+ generates defects, which increase background current due charge recombination and consequently degrade device performance. This review explores use two-dimensional (2D) materials additives enhance performance stability THPSCs. 2D improve transport, passivate induce vertical alignment, structural against moisture. Additives optimize film morphology interface properties by promoting grain growth reducing density. These approaches power conversion efficiency THPSCs up 15%, demonstrating commercial potential. The synergistic effects analyzed, critical strategies for combined utilization suggested develop high-efficiency stable
