Processing method for high anti-reflective glass for packaging solar battery pack

Abstract

The invention provides a processing method for high anti-reflective glass for packaging a solar battery pack. The method has the advantages of high controllability, low production cost and simple process; and the prepared coated glass for packaging the solar battery pack has the advantages of high surface quality, high mechanical strength and obvious anti-reflection effect. The method comprises the following steps of: firstly, preparing SiO2 anti-reflection film solution; secondly, plating a film on the surface of glass with the SiO2 anti-reflection film solution; and finally, performing toughening treatment on the coated glass at a high temperature. The method is characterized in that: the preparation of the SiO2 anti-reflection film solution comprises the following steps of: adding a diluent into silicic ester at normal temperature, wherein the volume ratio of the silicic ester to the diluent is 1:(5-20); sequentially adding water and a hydrolysis catalyst with violently stirring, wherein the volume ratio of the silicic ester to the water is 1:(0.1-0.3) and the volume ratio of the silicic ester to the hydrolysis catalyst is 1:(0.005-0.15); regulating the pH of the reaction system to between 2 and 5, adding 1 to 5 grams of lithium magnesium silicate, and hermetically stirring the mixture for 2 to 10 hours; and aging the stirred mixture for 7 to 15 days at room temperature, wherein the gram / liter ratio of the lithium magnesium silicate to the silicic ester is 2:3.

Description

technical field [0001] The invention relates to the technical field of solar cell module production, in particular to a processing method of high anti-reflection glass for solar cell module packaging. Background technique [0002] In the 21st century, natural resources are increasingly scarce and energy is increasingly scarce. These have become the main problems and challenges facing the world today. For the sustainable development of human beings, human beings must be required to take active measures in seeking new environmentally friendly alternative energy sources. Solar energy is an inexhaustible clean energy, and effective use of solar energy will greatly alleviate these problems and challenges. Since Bell Laboratories in the United States made a practical monocrystalline silicon solar cell for the first time in 1954, solar cells have always been a hot spot in the field of scientific research and industrial application. After decades of hard work, the research on solar...
