Abstract Energy demand has dramatically increased globally, posing a serious risk of future energy crises. While various sources have been utilized, solar emerged as the most promising renewable option, convertible to electrical via cells. Among developed cells, perovskite cells (PSCs) recently received significant attentions due their simple fabrication, high performance, and cost‐effectiveness. In particular, lead (Pb) halide‐based PSCs achieved highest power conversion efficiency. However, despite excellent Pb are hindered by toxicity in structures. Consequently, researchers explored germanium (Ge) tin (Sn) halide materials for development Pb‐free (LFPSCs). The past few years seen rapid advancements numerical simulation LFPSCs using SCAPS software. These studies crucial developing with enhanced performance.

Two-dimensional (2D) perovskites have been widely adopted for improving the performance and stability of three-dimensional (3D) metal halide perovskite devices. However, rational manipulation phase composition 2D suitable energy level alignment in 2D/3D photodetectors (PDs) has rarely explored. Herein, we precisely controlled dimensionality on CsPbI2Br films by tuning polarity n-butylammonium iodide (BAI)-based solvents. In comparison to pure n = 1 (ACN-BAI) formed acetonitrile treatment, a mixture 2 phases (IPA-BAI) generated isopropanol (IPA) treatment guaranteed more robust defect passivation favorable at perovskite/hole transport layer interface. Consequently, IPA-BAI PD exhibited responsivity 0.41 A W–1, detectivity 1.01 × 1013 Jones, linear dynamic range 120 dB. Furthermore, mixed-phase effectively shielded 3D from moisture. The device retained 76% its initial after 500 h nonencapsulated storage 10% relative humidity. This research provides valuable insights into dimensional modulation further enhancing PDs.
