Description
Technical Field
The disclosure relates to the technical field of photovoltaics, in particular to a coating material, application of the coating material in glass for a photovoltaic module and the photovoltaic module.
Background
The traditional photovoltaic module is mainly of a single glass structure, and the structure of the traditional photovoltaic module is that: front plate glass (3.2 mm fully tempered+AR film glass), EVA, battery pieces, EVA and a high polymer backboard. Along with the popularization of the double-sided battery, the duty ratio of the double-sided component is gradually increased, and at present, the duty ratio of the double-sided component reaches more than 50%, and correspondingly, the structure of the double-sided component is as follows: front plate glass (2.0 mm semi-tempered and AR film glass), EVA, battery cells, EVA and back plate glass (2.0 mm semi-tempered). Meanwhile, in order to ensure that sunlight is utilized to a greater extent, the back plate glass battery piece gap is subjected to high-reflection glaze plating treatment. Through the process treatment, the assembly efficiency can be improved by about 1%, and the structure is as follows: front plate glass (2.0 mm semi-tempered and AR film glass), EVA, battery cells, EVA, and back plate glass (2.0 mm semi-tempered and reflective frit).
However, in practical application, the back glass coated with the reflective glaze is more prone to breakage than the back glass not coated with the reflective glaze. The reason for this is mainly as follows: firstly, the preparation process of the reflective glaze layer mainly comprises screen printing, curing and tempering. The main component of the reflective glaze is TiO 2, and in the tempering treatment process, tiO 2 in the glaze layer can enter the surface of the glass to influence the components and the structure of the surface of the glass, and defects are generated at the contact place of the glaze layer and the glass. Resulting in the strength of the back glass of the enamel layer being lower than the strength of the back glass without the enamel. And secondly, the thermal expansion coefficient of the reflective glaze layer is different from that of the glass, and the sample is rapidly cooled from about 700 ℃ in the tempering treatment process, so that larger stress exists between the glass and the reflective glaze.
Therefore, how to improve the efficiency of the photovoltaic module and simultaneously ensure the yield of the glass is a problem to be solved in the field.
