光学设计用于全固态电致变色器件的高溅射效率三明治结构电解质
Sandwich Structured Electrolyte of High Sputtering Efficiency for All-solid-state Electrochromic Devices by Optical Design
摘要
Abstract
The all-solid-state electrochromic devices(ECDs)have been widely developed for energy-saving windows,screen displays,multi-functional energy storage devices due to their characteristics such as large optical contrast,fast switching speed and good cycle stability.However,traditional all-solid-state ECDs based on monolayer electrolyte system are often limited by ordinary optical transmittance and inadequate sputtering efficiency.Herein,the all-solid-state ECDs integrated with LiAlOx/Ta2O5/LiAlOx(ATA)sandwich structured electrolyte were successfully fabricated by reactive DC magnetron sputtering technique.By means of introduction of ATA sandwich structured electrolyte,the prepared ECDs with seven layer(ITO/NiO/LiAlOx/Ta2O5/LiAlOx/WO3/ITO)was endowed with superfine optical transmittance and substantial sputtering efficiency simultaneously.The ATA-based ECDs realized satisfactory coloration efficiency of 79.6 cm2/C,fast switching speed as short as 1.9 s for coloring and 1.6 s for bleaching,and excellent cycling stability over hundreds of cycles.Furthermore,ATA sandwich structured electrolyte makes full use of the excellent ionic conductivity and stability of Ta2O5,as well as enough lithium ions to meet the demand for fast color switching.Hence,ATA-based all-solid-state ECDs by continuous DC sputtering is expected to provide effective guidance for the mass production and practical application of the high-performance ECDs.关键词
