摘　　要：Effective perovskite crystallization control strategies for flexible substrates with scalable processing techniques have rarely been reported and remain an important challenge.In this study,3-mercaptobenzoic acid(3-MBA)was introduced into the perovskite precursor to modulate the crystallization dynamics,facilitating rapid nucleation while slowing down crystal growth.This approach enabled the formation of uniform,dense large-area perovskite films on flexible substrates.Consequently,a 12 cm^(2) flexible perovskite solar module achieved a power conversion efficiency(PCE)of 16.43%.Additionally,the module exhibited enhanced mechanical stability under various bending radii and improved light stability,marking a substantial advance toward the practical application of flexible perovskite solar modules.

关 键 词：FLEXIBLE perovskite solar modules bending stability crystallization.
