Surface quasi periodic and random structures based on nanomotor lithography for light trapping

Abstract : We compare the characteristics of two types of patterns obtained with two azopolymer materials: aGaussian random pattern and a quasi-random grating pattern. The surface structurations have beenobtained with a simple bottom-up technique, illuminating azopolymer thin films with a single laserbeam. We demonstrate the interesting generated properties of these two surfaces. In particular, thesurface with quasi-random gratings can address beam splitting for light coupling in different direc-tions in an ultra-thin film. We use these two surfaces as a mold and replicate them on a transparentelastomeric material and demonstrate a very good light entrapment. We also show that the efficiencyof light trapping is 20% better with the quasi-random gratings, than with the Gaussian random sur-face, and is close to 40%.Published by AIP Publishing.
