Determination of the optical properties in transparent conductive electrodes based on an indium-tin oxide coating using the IAD method

The optical properties of transparent conductive electrodes (TCEs) based on indium tin oxide (ITO) films deposited on polyethylene terephthalate (PET) substrates were evaluated in this work making use of the Inverse Adding-Doubling (IAD) iterative method. This technique allowed us to obtain the scattering and absorption coefficients explaining the optical behavior of the ITO-PET samples. The results pointed out that absorption is the most noticeable optical extinction process that occurs when light travels through this material.
