The transmittance range of amorphous tungsten oxide (a-WO3) smart windows can vary depending on several factors, such as the fabrication process of the a-WO3 thin film, its thickness, doping conditions, the applied voltage, and external environmental conditions. However, general estimates for transmittance values are as follows:
- Colored State (Low Transmittance):
In the colored state, where the a-WO3 film is darkened by an applied voltage, the transmittance can significantly decrease, typically down to around 10% or lower. The exact value depends on the film’s manufacturing process and testing conditions. - Bleached State (High Transmittance):
In the bleached state, where the a-WO3 film becomes transparent, the transmittance can increase to around 80% or higher. This high transmittance is one of the key features that makes a-WO3 smart windows suitable for energy-efficient building applications. - Device and Environmental Impact:
The transmittance adjustment range in smart windows also depends on the device design and external environmental factors. By optimizing the device structure and controlling the applied voltage, a wider range of transmittance adjustments can be achieved. Additionally, smart windows can dynamically adjust transmittance based on external factors like sunlight intensity and temperature, which helps maintain indoor comfort and energy efficiency. - Dynamic Adjustment:
It’s important to note that the transmittance of a-WO3 smart windows changes dynamically as voltage is applied or removed. Therefore, the exact adjustment range can be tailored to specific application needs, offering flexibility in different usage scenarios.
In summary, the transmittance range of a-WO3 smart windows typically spans from about 10% to 80%, but the exact values can vary depending on the fabrication and operational conditions. To obtain more precise performance parameters, it’s recommended to refer to specific research literature and experimental data.
