Investigation of Parameters of Transparent Conducting Periodic Structures Manufactured by Laser Ablation

Abstract

In this paper we report on results of an investigation of a transparent mesh electrode in a wide wavelength range 550–2000 nm with low electrical resistance manufactured by laser ablation with using an aluminum film with a thickness of 30 pm on a polyimide substrate with a thickness of 20 μm. The method is implemented using a fiber ytterbium nanosecond laser with a wavelength of radiation 1064 nm. The structure we have obtained has a transmittance >50% in the designated spectrum range and the electrical resistance <1.5 Ω/sq.
