Sticker-type transparent antireflective film (STAF) is applied to perovskite solar cells (PSCs) reduce the reflection and improve light-trapping ability of PSCs. However, development STAF hindered by many factors, such as expensive materials, low actual service life, unsatisfactory effect, a lack research on stability. This work proposes an ultraviolet (UV)-resistant enhanced sticker-type nanostructure acrylic resin (SNAAF), which incident surface SNAAF prepared using cleverly designed two-step peeling transfer process. The average reflectance related device reduced 4.06% through entire visible light spectrum, also helps achieve champion performance PSCs with STAF. excellent antireflection increases power conversion efficiency (PCE) from 20.77% 22.1% owing significantly short-circuit current density 5.5% SNAAF. Additionally, target maintains nearly 80% its initial PCE after 480 h irradiation UV (365 nm), far exceeding exposure levels in IEC 61215. Moreover, applicable large-area Cu(In, Ga)Se2 (CIGS) (area: 225 cm2), develops practical external engineering strategy for optimizing different types commercial cells.
