Built‐In Electric Field‐Assisted Polyaniline for Boosting Dual‐Band Electrochromic Smart Windows with Multicolor Displays and Four‐Mode Conversion

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

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.
