New energy industry is the key to national sustainable development. Machine vision in automatic inspection will play an important role in the transformation and upgrading of photovoltaic, lithium batteries and other new energy industry manufacturing process. Machine vision inspection can not only realize the detection and sorting of internal defects and impurities of silicon wafers and cells, but also measure the dimension and quality of products, detect appearance defects , so as to improve production efficiency and product quality.
Photoluminescence (PL) Detection
During the production of photovoltaic panels, problems such as hidden cracks, uneven diffusion and void may occur. These defects may affect the photovoltaic conversion efficiency, reduce the life of the cell and affect the stability of the Photovoltaic sy
Electroluminescence (EL) Detection
Most PV cells currently use silicon material as the substrate, which can be divided into crystalline silicon cells and amorphous silicon cells. Some structural defects such as micro-cracks, finger-interruption, contamination or cell inter-connection degra
