Solar cell automatic sorting instrument

　　Solar energy is currently one of the more widely used types of energy by humans. The reason why solar cell modules can play their role is because they are devices that directly convert light energy into electrical energy through photoelectric or photochemical effects. Thin film solar cells that work with photoelectric effects are a mainstream application. If distinguishing the quality of solar cells and how to classify them into grades is a major challenge for people, it is impossible to accurately judge whether there are defects in solar cells with the naked eye. The solar cell sorting instrument is a specialized equipment for sorting amorphous silicon, polycrystalline silicon, and monocrystalline silicon solar cells.

　　The solar cell sorting instrument screens out hidden cracks, fragments, virtual soldering, black chips, broken grids, mixed grades, color differences, and other solar cells through initial selection, ensuring the quality of components and the smooth and efficient operation of production. Due to the randomness of the production conditions of battery cells, the performance of the produced batteries may vary. Therefore, in order to effectively combine batteries with consistent or similar performance, they should be classified based on their performance parameters; The solar cell sorting instrument classifies the output parameters (current and voltage) of the battery by testing them. To improve the utilization rate of batteries and produce high-quality battery components.

　　The YOHA solar cell automatic sorting instrument uses a high-definition industrial camera to first detect EL defects in the battery cells. The battery cells with defects such as hidden cracks, fragments, virtual soldering, black chips, broken grids, mixed grades, color differences, etc. are selected, and then the output parameters of the battery cells are tested using imported xenon lamps to simulate sunlight. The performance parameters of the battery cells are calculated through customized software. Then classify according to its performance parameters. To use a solar cell automatic sorting instrument, it is necessary to first calibrate the sorting instrument with a standard sheet, and then test and sort the solar cells. The sorting instrument adopts fully automatic mode and performs battery cell sorting at high speed. The equipment has four loading boxes and 24 unloading boxes, making it convenient for users to classify more finely.
