Abstract 2D Ruddlesden‐Popper (RP) perovskites have garnered increasing attention for their excellent photoresponse, characterized by high carrier mobility, tunable bandgaps, optical absorption, and molecular asymmetry. Herein, centimeter scale single crystal hybrid perovskites, BA 2 PbBr 4 (BPB) is synthesized, using quasi‐static cooling method composited with ferroelectric PVDF‐TrFE(PT) film to construct a multi‐field coupling photodetector (PD) via van der Waals force contact. Ferroelectric tests show that the PT exhibits saturated polarization strength of 3.6 µC cm −2 , allowing localized field modulate band structure enhance photocurrent. The Heterojunction systems exhibit ultra‐high responsivity (15.3 A W −1 ) detectivity (1.99 × 10 13 Jones) under 390 nm illumination at 3 V bias, performance improvement over times compared BPB PDs. Furthermore, PDs highly stable I–t curve photocurrent retention rate 97.4%. Leveraging this feature, large‐area imaging device designed level scale, enabling multifunctional vision applications accurate letter process anti‐interference number detection. work presents valuable insight in design future autonomous driving systems.

Organic–inorganic hybrid perovskite solar cells (PSCs) have shown impressive photoelectric conversion efficiency (PCE) but suffer from inevitable degradation when exposed to air and light. Replacing the organic cations with inorganic Cs+ yield all-inorganic CsPbX3 perovskites can improve stability under environmental pressure. Among them, cesium lead bromide (CsPbBr3) shows great tolerance illumination, humidity, heat, oxygen attack. However, energy gap between carbon electrode CsPbBr3 limits carrier separation–transfer rate. Herein, p-type charge-transfer-doped NiO nanocrystals are employed as hole transport materials in PSCs a fluorine-doped tin oxide (FTO)/SnO2/CsPbBr3/NiO-l-Cys/carbon structure. This combination reduces charge-carrier recombination by decreasing potential energy-level barrier layer. The coordination of structure associated interfacial charge extraction–transfer action leads remarkable enhancement PCE (9.61%) much higher open-circuit voltage (1.614 V), surpassing those achieved hole-free devices (7.35% 1.504 V, respectively). PSC device assembled displays good high humidity temperature for 30 days. greatly improved PCE, coupled stability, demonstrates l-cysteine-doped future use hole-transporting material PSCs.
