Transparent Conductive Oxides (TCOs) are a unique class of materials that combine two typically opposing properties—optical transparency and electrical conductivity. These materials play a critical role in a wide range of modern technologies, particularly in optoelectronics and energy-efficient devices.
TCOs are typically composed of metal oxides such as Indium Tin Oxide (ITO), Aluminum-doped Zinc Oxide (AZO), and Fluorine-doped Tin Oxide (FTO). These compounds are engineered to allow visible light to pass through while simultaneously conducting electricity, making them ideal for applications where both light transmission and electrical function are essential.
Characteristics of TCOs：
Wide bandwidth: The bandwidth of TCO films can be modulated by doping and other means to meet different photovoltaic needs. For example, zinc oxide (ZnO) films can achieve diverse optoelectronic properties through different doping elements.
Low resistivity: TCO films have low resistivity, which enables them to transmit charge effectively while maintaining high visible light transmittance. For example, Indium Tin Oxide (ITO) film has become an ideal transparent conductive material for large-area electronic devices such as liquid crystal displays due to its excellent conductivity and high transmittance.
Optical transparency and light reflection properties: TCO films have high transmittance in the visible region, which allows them to transmit light efficiently and reduce the loss of optoelectronic devices. At the same time, they have high reflectivity in the infrared spectral region, which is suitable for the preparation of special functional materials such as infrared window coatings.
