Abstract

The invention relates to the field of manufacture of packaging glass for solar cells, and especially relates to a multi-step catalyzed composite sol for anti-reflection coating, and anti-reflection coated photovoltaic glass manufactured by the composite sol. The composite sol for anti-reflection coating is prepared from the following raw materials by the following method which comprises steps of: preparing sol A, preparing sol B, preparing composite sol C, preparing composite sol D, preparing composite sol E, and preparing the composite sol for anti-reflection coating. An anti-reflection film coated by the sol only needs coating once; therefore the production cost is low, and the process is high-efficient and easily-controlled; the composite sol of the invention is suitable for large-area coating production of photovoltaic glass; the coated product can pass related examinations, such as film hardness, adhesion, and weatherability.

Description

technical field [0001] The invention relates to the field of manufacturing packaging glass for solar cells, in particular to a multi-step catalyzed composite sol for anti-reflection coating and photovoltaic glass with anti-reflection coating manufactured by using the composite sol. Background technique [0002] In recent years, with the deterioration of the global environment and the rise of traditional energy market prices, countries around the world have introduced strategies to promote the utilization and development of new energy. Clean, safe and convenient silicon-based solar cells can not only be used on roofs and walls on a small scale to provide daily electricity for buildings, but also can be built on a large scale in areas rich in sunshine resources and connected to the grid for power generation. focus on. When the solar cell is working, the light first passes through the uppermost encapsulating glass and enters the cell component, and then is converted into elect...
