As the proportion of buildings energy consumption increases, the issue of low energy utilization efficiency becomes increasingly prominent. Approximately 45% of the energy is lost through doors and windows, a significant concern that has drawn society's attention to the potential of electrochromic technology, which can regulate light transmittance and absorption effectively. Specifically, dual‐band electrochromic materials offer a promising solution to this issue, as they can manipulate the transmission ratios of visible (VIS) and near‐infrared (NIR) light to obtain “bright,” “cold,” “warm,” and “dark” independent modes. However, research on dual‐band electrochromic materials and smart windows is still infant, and many challenges including performance and assembly issues, are significant obstacles to the advancement and application of this technology. This review clarifies the basic characteristics of dual‐band electrochromic materials and smart windows, including configurations, operational mechanisms, and performance assessment parameters. In‐depth examination of potential dual‐band electrochromic materials and methods for achieving independent modulation is provided, along with an analysis of the challenges and potential solutions for performance and assembly issues. Finally, the future prospects of dual‐band electrochromic smart windows (ESWs) are underscored. The hope is to eventually facilitate the commercial application of these windows, which can significantly contribute to the creation of modern, energy‐efficient buildings.

Electrochromic smart windows (ESWs) can significantly reduce energy consumption in buildings, but their cost‐effective, large‐scale production remains a challenge. In this study, the instability of black phosphorus is leveraged to induce the growth of the tungsten oxide film through its decomposition process, inspired by the 2D material‐assisted in situ growth (TAIG) method. This approach results in the preparation of large‐scale, high‐performance WO3‐x·nH2O (n < 2) films. Characterization techniques and DFT calculations confirm efficient regulation of structural water and oxygen vacancies during TAIG preparation. The WO3‐x·nH2O films exhibit excellent electrochromic (EC) properties, including high transmittance modulation (74.2%@1100 nm), fast switching time (tc = 5.5 s, tb = 3.8 s), high coloration efficiency (124.7 cm2 C−1), and superior cyclic stability (transmittance modulation retained 94.7% after 20 000 cycles). Ultra‐large WO3‐x·nH2O film are prepared via a simple immersion process, and fabricated into a large‐area ESW under facile laboratory conditions, demonstrating the economic and practical feasibility of this approach in industrial‐scale production. Operated by the intelligent control circuit, the ESW exhibits remarkable EC properties and cyclic stability This research represents a milestone in improving the performance and industrial‐scale production of ESWs, bridging the gap to the commercialization of EC technology.
