Optimizing ultrathin NiO layers via sputtering to achieve cost-effective and energy-efficient electrochromic smart windows for modern infrastructure automobile industries.
Theoretical and experimental studies are performed to establish the importance of a thin overlayer on metal mesh as an ITO-alternative transparent conducting electrode for liquid crystal smart windows where uniform electric field is essential.

Energy-efficient glass windows are pivotal in modern infrastructure striving toward the "Zero energy" concept. Electrochromic (EC) energy storage devices emerge as a promising alternative to conventional glass, yet their widespread commercialization is impeded by high costs and dependence on external power sources. Addressing this, redox potential-based self-powered electrochromic (RP-SPEC) introduced leveraging established EC materials like tungsten oxide (WO
Electrochromic (EC) devices are not commercialized extensively owing to their high cost. The best large-area in the market suffer from reaching a distinct dark-colored state.
