Abstract: A method to prepare low reflective surface according to an example of the present invention comprises: the first step to prepare materials having pillar structure on the surface; the second step to prepare aluminum surface-materials by treating for the pillar structure to have aluminum surface; and the third step to prepare a low reflective surface with dual protuberance structure by forming nano-flake layer on the pillar surface of the material surface through oxidation of the surface aluminum of the aluminum surface-materials. The method to prepare low reflective surface can provide a low reflective surface structure that can be applied to photovoltaic device surface or various display surface as a surface able to reduce reflection significantly by absorbing wavelengths in the range of visible and infrared ray through internally total reflection with simple, low cost, and ecofriendly process.
