Perovskite solar cells (PSCs) captivate tremendous interest thanks to high-efficiency and low-cost. Nevertheless, the planar PSCs are negatively affected by serious reflection loss usually because of the refractive index mismatch between the glass substrate and the air, which limits their light harvesting per-formance. Here, we report an investigation for highly efficient PSCs with light management by applying a structural antire-flective film made of polydimethylsiloxane (PDMS) pyramidal texture. Machine learning is firstly used to predict planar (FAPbI3)0.95(MAPbBr2.2Cl0.8)0.05 PSC' performance for an ex-perimental guide. The experimental results show excellent agreement between the two. When the antireflective film is utilized in the present planar PSCs, an impressive light absorption enhancement is achieved, resulting in a significantly increased power conversion efficiency of up to 23.5%.
