description To produce highly efficient and repeatable perovskite solar cells (PSCs), comprehending interfacial loss and developing approaches to ameliorate interfacial features is essential. Nonradiative recombination at the SnO<sub>2</sub>–perovskite interface in SnO<sub>2</sub>-based perovskite solar cells (PSCs) leads to significant potential loss and variability in device performance. To improve the quality of the SnO<sub>2</sub> electron transport layer, a novel polymer-doped SnO<sub>2</sub> matrix, specifically using polyacrylic acid, was developed. This matrix is formed by spin-coating a SnO<sub>2</sub> colloidal solution that includes polymers. The polymer aids in dispersing nanoparticles within the substrate and is evenly distributed in the SnO<sub>2</sub> solution. As a result of the polymer addition, the density and wetting properties of the SnO<sub>2</sub> layer substantially improved. Subsequently, perovskite-based photovoltaic devices comprising SnO<sub>2</sub> and Spiro-OMeTAD layers and using (FAPbI<sub>3</sub>)<sub>0.97</sub>(MAPbBr<sub>3</sub>)<sub>0.03</sub> perovskite are constructed. These optimized devices exhibited an increased efficiency of 17.2% when compared to the 15.7% power conversion efficiency of the control device. The incorporation of polymers in the electron transport layer potentially enables even better performance in planar perovskite solar cells.
