Abstract

Energy saving electrochromic windows were achieved by controlling the interfacial charge transfer using low-HOMO level (EHOMO < −5 eV) π-conjugated polymers (CPs) as bistable electrochromic films and an ionic liquid as the electrolyte layer. It provided a long bistability (>90 min) at the voltage-off state with a high coloration efficiency (879 cm2 C−1).
