The polycrystalline perovskite films treated with solutions inevitably are subjected to high‐density crystal defects, significantly affecting the performance and stability of perovskite‐based photodetectors. In this research, a reasonably designed organic small molecule using piperazine iodide (PI) as an additive is employed to modify the perovskite films. The results indicate that this designed molecule not only improves the crystallinity of the perovskite film but also effectively passivates defects by modifying the local electron density. Consequently, recombination of non‐radiation charges is inhibited, improving the optoelectronic performance and stability of the device. The modified flexible photoelectric device exhibits a responsivity of 3.07 mA W−1 under 405 nm laser illumination. Notably, it maintains a high responsivity even after 7000 bending cycles. Furthermore, generality of the strategy is verified by applying it to various types of two‐dimensional organic–inorganic hybrid perovskite. Additionally, another small molecular amine phthalimide (PTM) is selected as an additive to further verify the universality of this strategy, which reveals that it demonstrates the same passivation as PI. This strategy provides a novel idea for defect passivation of two‐dimensional organic–inorganic hybrid perovskite, signifying a practical application significance for developing flexible wearable devices with optimized performance, perovskite light‐emitting diodes, and solar cells.

Single‐crystal hybrid perovskites represent an emerging class of next‐generation semiconductors due to their excellent and tunable optoelectronic properties, along with a solution‐based, low‐temperature growth process. 2D single‐crystal hybrid perovskites are especially promising as their long‐range ordered multiple quantum well structure induces many peculiar properties, such as large exciton binding energy, large in‐plane conductivity, and improved environmental stability, which make them suitable for low‐dimensional optoelectronics applications and fundamental studies. Herein, the structural properties, morphology, and optoelectronic behavior of 2D thin film phenethylammonium lead iodide (PEA2PbI4) single‐crystals, synthesized using the space‐confined growth technique are explored. A planar device is fabricated and its spectral photoresponse is studied under broadband supercontinuum white light. Remarkably, the device exhibits an ultra‐low dark current (10−14 A), indicative of low defect density and suppressed ion migration. Under white light, the current increases linearly with the incident power, up to a factor of 105, and the device achieves a specific detectivity of 109 Jones. The temperature and wavelength dependence of the photocurrent suggests the dissociation of excitons as one of the main mechanisms affecting photoconduction. Furthermore, stability under air exposure and illumination turns out to be remarkable.
