Abstract

A solar module detection method is used to detect the solar cells of a solar module. The detection method comprises a powering-on step: making solar cells electroluminescent; an image capture step: capturing an image of the solar cells emitting light; a luminous intensity analysis step: analyzing the captured image; a detection object selection step: finding out solar cells with low luminous intensity; and a detection step: detecting the solar cells with low luminous intensity. If a solar cell is of lower luminous intensity, the photoelectric conversion efficiency of the solar cell is poorer, and the current produced by the solar cell is lower. In the detection step, only a few decisive solar cells are detected. Thus, there is no need to detect all the solar cells in the detection method, the detection efficiency is improved, and time and labor are saved.

Description

[0001] 【Technical field】 [0002] The invention relates to a detection method, in particular to a detection method of a solar module. [0003] 【Background technique】 [0004] A solar cell is a battery that converts light energy into electrical energy for use. In use, several solar cells are usually arranged in a two-dimensional array between two plates spaced up and down, and the solar cells are connected by welding ribbons. They are electrically connected to each other, and the solar cells are covered by the encapsulation material to be packaged into a solar module. Afterwards, related performance tests will be carried out on the solar module, such as through spectral response (Spectral Responsivity, SR) testing, to understand the photoelectric conversion capability of the solar cell after packaging. [0005] However, in the existing detection methods, each solar cell of the solar module is detected one by one. On the other hand, due to the increasing size of the current sol...
