摘要

本研究利用增透理论设计了具有超高透光率的wo3基电致变色薄膜。结果表明，当WO3膜的厚度为539 nm时，薄膜在550 nm处的透过率可达90.08%，是我们所知的研究中最高的。在1000次循环后，薄膜也表现出良好的循环稳定性，光调制率损失仅为13%，电荷容量损失为31.54%。我们相信这一研究将为超高透过率电致变色薄膜的设计提供新的思路。

Applying the antireflection theory in designing of ultra-transparent WO3-based electrochromic films

In this study, the antireflection theory is used to design WO₃-based electrochromic films with ultra-high optical transmittance. The results show that transmittance of the films at wavelength of 550 nm could reach 90.08 % when the thickness of WO₃ film is 539 nm which is the highest among previous studies to our knowledge. And at this time, the films also shows good cyclic stability with only 13 % optical modulation rate loss and 31.54 % charge capacity loss after 1000 cycles. We believe that this research would provide a new insight into design of electrochromic films with ultra-high optical transmittance.
