Highly transparent to deep black electrochromic smart windows based on liquid crystals

초록

This study introduces advanced organic electrochromic devices (ECDs) that incorporate liquid crystals (LCs) to achieve tunable light transmittance, enabling seamless transitions between a highly transparent and a deep black state. By integrating LCs with redox-active components, the proposed ECDs exhibit precise electrochromic color modulation upon voltage application. A detailed investigation of chromatic transitions and electro-optical properties reveals fast response times, enhanced stability, and strong potential for smart window and display applications. A comparative analysis with existing technologies, including guest-host LC (GHLC), and polymer network LC (PNLC) systems, highlights the superior performance of the proposed devices in terms of transmittance modulation, privacy control, and energy efficiency. These findings position LC-based ECDs as promising candidates for next-generation smart windows, energy-efficient privacy management, thermal regulation, and high-performance display technologies.
