Method for detection optical property of coated glass

Abstract

The invention discloses a method for detection optical property of coated glass. The method comprises the following steps of 1, sampling; 2, cutting; 3, detecting the optical property of the coated surface; 4, detecting the optical property of the non-coated surface; 5, calculating the gain of the optical property. The method has the advantages that the light transmittance of same coated glass is detected by the same light transmittance tester, so that the purpose of testing the anti-reflection rate of the coating layer of the same glass sample on the same testing instrument is realized; the glass sample is cut into a cube shape, so that the removing of the coating layer is not needed in the detection process, the unnecessary steps are reduced, and the time for implementing the method is shortened; the inherent error of testing data is eliminated, the quality of the coating layer in the coating procedure is truly reflected, the processing quality of coating in the film plating procedure is conveniently monitored, the quality of a photovoltaic glass product is improved, and the method is suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of glass detection, in particular to a method for detecting optical properties of coated glass. Background technique [0002] As an indispensable tool in daily life, glass has a wide range of uses. For the optical properties of glass, the most critical performance is the light transmittance. For the glass used to match solar panels, improving the light transmittance is the It can increase the power generation power of the battery panel per unit area. Research shows that coating the glass can further improve the light transmittance of the glass on the basis of the glass. [0003] After the glass is coated, its light transmittance is different from that of the original glass before coating. The purpose of coating is to increase the light transmittance of the glass as a whole. The optical performance test of the coated glass is to quantify the part of the light transmittance increased by the coating layer. It ...

Problems solved by technology

[0004] Most of the previous detection methods for the increased light transmittance of the coated photovoltaic glass coating layer are the overall measurement method, mainly including: off-line test method and on-line test method, both off-line test methods and on-line test methods cannot overcome different glass or Due to the inherent errors caused by different testing instruments, it is impossible to accurately quantify the increased transmittance of the coating layer, and it is also impossible to judge the quality of the coating process, the quality of the coating layer, and evaluate the quality of the coating layer.

[0005] In the prior art, the method for detecting light transmittance of coated photovoltaic glass with the publication number "CN103528998A" has solved the problem of errors caused by different glasses and different testing instruments that could not be solved by the previous off-line test method and on-line test method. problem, but in this detection method, there is an obvious defect: in the detection step, the coated glass needs to be removed, which makes the detection process cumbersome
