Abstract

Windows contribute significantly to heat loss in buildings, making them a critical focus for energy-saving measures aimed at reducing the substantial energy consumption in the building sector. This study explores ’high-transmittance, low-emissivity’ windows, which is beneficial for energy conservation in cold regions. Numerical calculations and experimental validation were used to develop a novel material optimization strategy utilizing hydrogen-doped indium oxide (IHO) films. The optimized IHO films exhibit high mobility (100 cm2/V·s) and low carrier concentration (2.2 × 1020 cm−3), providing superior performance compared to traditional transparent conductive oxide (TCO) films. The developed low-emissivity (low-e) passive insulation composite film demonstrates enhanced spectral characteristics. It achieves a solar transmittance of 0.836 and a mid-infrared (MIR) emissivity as low as 0.117, surpassing the performance of commercial low-e glass. This approach not only addresses the spectral limitations, such as poor NIR transmittance and high emissivity, of traditional low-e coatings but also establishes a universally applicable methodology for material selection and optimization.
