Abstract

The invention discloses a method for detecting light transmittance of coated photovoltaic glass. The method comprises the following steps: randomly sampling the photovoltaic glass after the coating process; performing light transmittance test to obtain the light transmittance of the photovoltaic glass with the coating layer. T1; remove the coating layer on the surface of the photovoltaic glass and conduct a light transmittance test to obtain the light transmittance T2 of the photovoltaic glass after removing the coating layer; obtain the light transmittance increase value T3 of the coating layer according to T1 and T2, T3=T1- T2. In the present invention, by testing the light transmittance of the coated photovoltaic glass sample, removing the coating layer on the same sample, and measuring the light transmittance of the sample after removing the coating layer on the same testing instrument, it is realized that the same test instrument The purpose of testing the anti-reflection rate of the coating layer on the same sample eliminates the inherent error of the test data, can truly reflect the quality of the coating layer in the coating process, and is convenient for monitoring the coating process quality of the coating process.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a method for detecting light transmittance of coated photovoltaic glass. Background technique [0002] Photovoltaic power generation has become an important direction for the development of new energy, but at present, in photovoltaic power generation, the photoelectric conversion efficiency is low. The existing ultra-clear embossed glass is an indispensable and important part of flat-panel solar cells. Its technology is mainly the rolling method, and it is made by embossing a special pyramid-shaped pattern on the surface of the ultra-clear glass. The key parameter of ultra-clear glass is the light transmittance. Increasing the light transmittance can increase the power generation of photovoltaic cells with equal efficiency per unit area. Photovoltaic glass coating can further improve the light transmittance of photovoltaic glass on the basis of ultra-clear embossed g...
