Embodiment 1

[0024] like figure 1 As shown, a test device for electrode tension in a solar cell assembly, the solar cell assembly includes a silicon cell 2, a welding ribbon 3 welded on the silicon cell, and the test device includes a device for installing and fixing the silicon cell Glass 1, and a tensile machine. One end of the tensile machine is connected to the glass 1, and the other end clamps the welding head of the ribbon 3. The tensile machine is started to test the separation force of the ribbon and the silicon cell.

[0025] The tension machine includes a separation end, a transmission device, a tension sensor, a main body of the tension machine, and a computer.

[0026] The separated end is composed of two opposite clamps, one of which is connected with the transmission device and the tension sensor and can move freely. The sensor is connected with the computer, and the tension value can be directly read through the computer. Among them, the clamp of the tensile machine is an ...

Abstract

The invention relates to a solar cell module electrode tension test device. A solar cell module comprises a silicon cell and a solder strip welded to the silicon cell. The test device comprises glass used for installing and fixing the silicon cell, and a tensile machine of which one end is connected with the glass and the other end clamps the welding head of the solder strip. After the tensile machine is started, the separation force between the solder strip and the silicon cell can be tested. Compared with the prior art, the test device can effectively increase the speed of cell electrode tension test, ensure the accuracy of electrode tension data, and the like.

Description

technical field [0001] The invention relates to solar energy, in particular to a device for testing the pulling force of electrodes in a solar cell module. Background technique [0002] In recent years, solar energy, as a clean and green renewable energy source, has received more and more attention, and its application is also very extensive. Among the various applications of solar energy, the most important application at present is photovoltaic power generation. With the emphasis on solar power generation in various countries, the proportion of photovoltaic power generation in the entire power generation system is increasing. [0003] The most basic unit of solar photovoltaic power generation is a solar cell. In a specific application, a plurality of solar cells are usually packaged to form a solar cell module, and then each solar cell module is connected to form an overall current output. Currently widely used solar cell components are mainly monocrystalline silicon cell...
