Electrochromic (EC) technology can adjust optical properties under electrical stimulation with broad applications in smart windows, displays, and camouflage. However, significant challenges remain developing inorganic EC films high durability, rapid response, mechanical flexibility due to intrinsic brittleness dense microstructure. Herein, a nanostructured quasiplanar heterointerface (Q-PHI) is first introduced into the electrode/EC interlayer realize robust, ultrafast switching tungsten trioxide (WO3) film. The 200 nm-thick Q-PHI WO3 film exhibits remarkable performance, including large contrast (81.8% 83.4% at 700 1500 nm), of 2.4 1.8 s, excellent stability (10,000 cycles 21.3% optical-contrast loss). A large-area (20 × 15 cm2) flexible window also successfully achieved. mechanism lies intense built-in electric field strong interfacial bonding induced by unique longitudinal gradient distribution, greatly enhancing electron/ion transport kinetics, surface ion adsorption, durability.

Abstract Dual‐band electrochromic smart windows (DESWs) can selectively adjust the transmittance of visible (VIS) and near‐infrared (NIR) light, significantly reducing building energy consumption. However, current DESWs face challenges in achieving multi‐color control fully independent modulation VIS NIR light. Herein, a DESW with display capabilities four distinct operational modes is presented, achieved by utilizing polyaniline (PANI) combination built‐in electric field. The field, formed at interface between Au PANI, enhances transport speed ions electrons during (EC) process, facilitating electronic transitions polarons, bipolarons, quinonoid units. This improvement EC performance Au/PANI Schottky junction films compared to pure PANI films. enhanced not only expands from three four, but also provides faster response times (τ c /τ b = 1.1/5.4 s 1600 nm, τ 0.9/1.3 633 nm) superior cycle stability. Additionally, large‐scale (5 × 5 cm 2 ) device demonstrated, effectively controlling both temperature light flux. incorporation field accelerates electron ion transfer, providing promising strategy for developing high‐performance applications energy‐efficient buildings.
