Investigation of IR Reflective Coating for Plexiglas Canopy

Purpose: Solar energy is necessary for our global ecosystem. In certain times and parts of the world, heat generated from Sun becomes uncomfortable us we need to use additional cool down Sun. This usage detrimental environment due generation air pollution natural resources. The purpose this paper investigate prevention undesired by using reflective coating materials.
 Methodology: study, literature review, Ga doped Zinc Oxide (GZO) theoretically investigated as a visible light transparent infrared material Plexiglas canopy solar car. effect doping concentration film thickness reviewed discussed. Indium Tin (ITO) also studied, various reviews, an that in region. Finally, spectrophotometer was used examine optical properties Plexiglas, slide glass, ITO coated results UV transmittance measurement three materials presented discussed.
 Findings: GZO films both have high transparency region spectrum reflectivity IR radiation starting 1500 nm higher wavelengths. None these completely reflect with wavelengths range 700 which contribute most. Many factors such affect their on shifting plasma frequency. Increasing until threshold improves films, but it not possible precisely formulate within study. Reducing particle size nanoparticle its reflectance showed glass near radiation.
 Recommendations: Further investigation experimentation recommended fully understand achieve optimal wavelength while maintaining transparency. regards coating, reduced improve desired film. Although coatings’ well understood reduce they are still above play role heat.
