Abstract

The optical properties of aluminum-doped zinc oxide (AZO) and tin-doped indium oxide (ITO) thin films on glass and the flexible polymer substrate (PET) are studied and are compared. The purpose of this study is to obtain optimal layers with a minimum specific resistance and a clear transparency in the visible area. In the AZO and ITO coatings, two anti-reflective coatings for different applications are designed to increase transmission by the MacLeod coating software. For the two coating types, the highest transmission through the visible area (400 to 700 nm) was 98.01% and 95.41% for the AZO coatings and 81.85% and 79.45% for the ITO coatings. Also, by changing the substrate from glass to PET for the single layer of AZO and ITO, the average percentage of light transmission increased, and the rate of change in light transmission per wavelength was decreased. For two types of anti-reflective coatings of AZO and ITO layers, by changing the substrate from glass to PET, the highest transmission in the visible area (400 to 700 nm) was to 97.87 and 96.18% for AZO coatings and 82.23% and 80.04% for ITO coatings.
