Investigation on sol-gel based coatings application in energy sector – A review

Abstract In most of the optoelectronics or photovoltaic based devices, different kinds of anti-reflection coatings on the substrate is mainly developed by sol-gel based coating process includes spin, dip and spray pyrolysis coatings. This paper enumerates in details regarding fabrication of thin films with its essential chemical procedures using sol-gel technique. Further it outlines about structural characterization and influences of physical and chemical parameters on the antireflection coatings prepare by sol-gel practice procedure. The essential coating on the substrate mainly depends on the heat treatment process, solution preparation and coating types using sol-gel application. The coated layer behaviour mainly relies on the ration of solvent to additive substances, concentration of taken precursor agent, and aging time of the solvent, thickness and substrate material of the coating. Among various coatings mainly anti-refection coating by sol-gel technique holds much attractiveness towards implementation due to its feasibility, low cost and compactness.
