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
