Abstract

The invention relates to a solar simulator irradiation uniformity testing device, the solar simulator irradiation uniformity testing device comprises a substrate and a base used for supporting the substrate, and a plurality of crossed warps and wefts are carved on the substrate to form a plurality of positioning reference frames with consistent sizes. In addition, the solar simulator irradiation uniformity testing device further comprises a battery piece adjusting device which is used for adjusting the position of a battery piece relative to the positioning reference frames. The battery pieceadjusting device comprises a sliding rod and a sliding block, wherein the sliding block is arranged on the sliding rod and can freely move in the left-right direction, and a positioning groove matchedwith the shape of the battery piece is formed in the sliding block. The sliding rod is arranged on the substrate and can freely move in the vertical direction. In this way, a traditional photovoltaicmodule substrate is abandoned, and the influence of the traditional photovoltaic module substrate on a test result is eliminated. In addition, the pollution caused by the fact that the battery pieceis taken for a plurality of times in the operation process is avoided, so that the position of the battery piece can be quickly and accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module detection, in particular to a solar simulator irradiation uniformity testing device. Background technique [0002] Photovoltaic module power test is one of the most important links in the production process of photovoltaic modules. The commonly used power test method is: the solar simulator emits simulated sunlight on the photovoltaic module, and the photovoltaic module is connected to the test instrument to measure its power. Therefore, the uniformity of solar simulator irradiation is particularly important for test results. At present, 72P156M photovoltaic module substrates are used to test the uniformity of irradiation of simulators in the industry, which are divided into 72 grids, and then the single cells are placed in the grids for testing. The change of the short-circuit current of the cell under the second flash pulse is converted into a voltage signal after IV calibration, so...
