Abstract

This study explores the challenges facing silicon-based Photodiodes (PDs) in color discrimination due to their thickness requirement and light absorption issues, prompting the investigation of perovskite halide materials as alternatives. However, the susceptibility of perovskite materials to degradation from humidity and oxygen remains a significant obstacle. To address this, the study proposes a novel approach involving the incorporation of PMMA/sodium borate salt (Borax) additives to reduce trap densities and enhance crystal quality in perovskite layers. The findings reveal that these additives act as passivators for Pb2+ ions and promote cross-linking between perovskite grains, leading to improved performance and stability of blue-light-targeting PDs. Specifically, the optimized Borax amount yields a PD with remarkable responsivity, external quantum efficiency, and stability, showcasing a promising pathway for future commercialization of photodiodes.
