Glass ink and highly reflective backsheet glass

Abstract

The invention relates to the technical field of photovoltaic glass, and provides glass ink and high-reflection backboard glass. The glass printing ink provided by the invention is composed of powder and an oil agent, wherein the powder comprises glass powder, titanium dioxide and an inorganic reducing agent, and the weight percentage of the inorganic reducing agent in the glass printing ink is 2%-5%. The glass ink is used for forming a high-reflection glaze layer of the high-reflection back plate glass, titanium dioxide in the high-reflection glaze layer is effectively prevented from being oxidized during PID testing by adding an inorganic reducing agent with a specific content into powder; in addition, the problem that the glaze layer of the high-reflection back plate glass changes colorduring PID testing is solved by means of the rutile type titanium dioxide.

Description

technical field [0001] The application belongs to the technical field of photovoltaic glass, and in particular relates to a glass ink and a highly reflective back glass. Background technique [0002] Solar photovoltaic glass is a special glass that is laminated into solar cells, can use solar radiation to generate electricity, and has related current extraction devices and cables. It is composed of low-iron glass, solar cell, film, back glass, and special metal wires. The solar cell is sealed between a piece of low-iron glass and a piece of back glass through the film. It is the most innovative high-tech building. Glass products. [0003] At present, double-glass modules are developing rapidly with an irresistible trend. Double-sided power generation can bring more power generation to the power station, thereby reducing the cost of electricity. Double-glass modules use high-reflective backplane glass, and add silk screen grid patterns on the basis of traditional backplane ...
