Solar cell performance detection equipment and method for detecting performance of solar cell

Abstract

The invention relates to the field of solar cells. The invention particularly relates to solar cell performance detection equipment and a method for detecting performance of a solar cell. The detection equipment comprises a main control system, a light intensity feedback device, an illumination device and a detection mechanism, wherein the illumination device and the light intensity feedback device are electrically connected with the main control system, and the light intensity feedback device uploads a first parameter generated after irradiation of the illumination device to the main controlsystem; the main control system judges whether the first parameter reaches a first preset parameter or not; if not, the illumination intensity of the illumination device is adjusted until the first parameter reaches a first preset parameter; if yes, the illumination device irradiates the to-be-detected battery piece; and the detection mechanism is electrically connected with the main control system, is conducted with the to-be-detected battery piece, acquires a second parameter generated after the to-be-detected battery piece is irradiated, and uploads the acquired second parameter to the maincontrol system. The main control system can adjust the illumination intensity according to the first parameter, so that the accuracy of the performance parameter of the to-be-detected battery piece can be improved.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to solar cell performance testing equipment and a method for testing the performance of solar cells. Background technique [0002] As a product that converts solar energy into electrical energy, solar cells are more and more popular due to their environmental protection and pollution-free. [0003] In actual situations, after the production of solar cells is completed, it is generally necessary to test the working performance of solar cells through testing equipment, and in the testing process, it is generally necessary to use an illumination device to irradiate the standard value of light intensity to the cells to be tested. , and obtain the power generated by the cell to be tested under the illumination of the light intensity of the standard value, so as to judge whether the performance of the cell to be tested is qualified. [0004] There are at least the following problems in the pri...

AI Technical Summary

Problems solved by technology

[0004] There are at least the following problems in the prior art. When the lighting device is set to the light intensity of the standard value, often due to the reasons of the lighting device itself, or because the lighting device has been used for too long, or due to the influence of electrical pressure, etc., the light emitted by the lighting device The actual light intensity does not reach the standard value, sometimes it is higher, sometimes it is lower, which indirectly leads to deviations in the measured performance of the cells to be tested, thereby reducing the performance of the detected performance parameters of the cells to be tested. Accuracy rate, thus affecting the qualification rate of production cells
