Model of the Relationship Between the Parameters of Smart Glasses Based on Fundamental Physical and Chemical Laws

Promising materials for producing transparent conductive oxides and electrochromic coatings included in the structure of electrochromic glasses are considered. Based on fundamental physical and chemical laws, models for coloring the material of an electrochromic panel and a model for the relationship between the parameters of smart glasses have been developed. Tungsten oxide, which has a visible light transmittance range from 0.1 to 0.8, was chosen as the electrochromic material. The simulation was carried out in two states: bleached and colored, with daylight illumination at a level of 500 lux over the panel area, and at a distance equal to two-thirds to the light source. The upper illumination limit in the model corresponds to the illumination value that causes the panel to switch between colorless and colored states. Potassium hexacyanoferrate acts as an anode. The process and reaction of coloring tungsten oxide is considered. The material coloring occurs due to light photons, which cause the transfer of electrons between the ion and the iron. Optical density, relaxation time, absorption coefficient and contrast ratio are also considered.
