Abstract The demand for high‐performance polarization‐sensitive perovskite photodetectors (PSPPDs) has driven research to develop new materials that enable efficient light harvesting and polarization detection. Herein, a PSPPD based on nanoimprinted quasi‐2D halide thin films with vertical gradient phase distribution is reported. nanoimprinting method utilized create nanoscale linear patterns the surface of film. It enables polarized detection enhances absorption. According results transient absorption analysis, along longitudinal direction (PEA) 2 (MA) n‐1 Pb n I 3n+1 (PEA + = C 6 H 5 CH NH 3 , MA 3) confirmed, which facilitates carrier transfer separation, leading improved device performance. These PSPPDs demonstrate outstanding photo‐response large responsivity ≈90 A W −1 high detectivity reaching order 10 12 Jones. photoluminescence film exhibits an anisotropy ratio 2.05, reaches sensitivity 1.68. findings offer insight into feasibility developing PSPPDs, have potential applications in imaging, sensing, communication technologies.

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.
