Optical Enhancement of Fluorine‐Doped Tin Oxide Thin Films using Infrared Picosecond Direct Laser Interference Patterning

Surface texturization of Transparent Conductive Oxides (TCOs) is a well-known strategy to enhance the light-trapping capabilities thin-film solar cells and thus, increase their power conversion efficiency. Herein, surface modification fluorine-doped tin oxide (FTO) using picosecond infrared direct laser interference patterning (DLIP) presented. The characterization exhibits periodic microchannels, which act as diffraction gratings yielding an in average diffuse transmittance up 870% spectral range 400–1000 nm. Despite one dimensionality microstructures, films did not acquire significant anisotropic electrical behavior, but partial deterioration conductivity observed result removal conductive material. This work proposes feasibility trading off portion obtain substantial improvement optical performance.
