6 FAQs about [Internal defects of solar cells]
Can solar cells detect internal defects?
Their system was based on bias flow to capture emissions of the solar cell, and image processing to recognize the internal defects. Their experimental results showed that the proposed system could successfully detect the internal defects of solar cells.
Can El images detect defects in solar cells?
The EL image can distinctly highlight barely visible defects as dark objects, but it also shows random dark regions in the background, which makes automatic inspection in EL images very difficult. A self-reference scheme based on the Fourier image reconstruction technique is proposed for defect detection of solar cells with EL images.
Why is it difficult to recognize a defect on a solar cell?
Because the finger lines are as emblems and located on background of solar cell, definitely any defect (crack, hole, etc.) is appeared on the finger lines or background. In this case, defect recognition is more challenging due to misdetection.
What are small cracks & breaks in solar cells?
Small cracks, breaks, and finger interruptions are severe defects found in solar cells. Some of the defects, such as interior small cracks, cannot be visually observed in the image with the conventional CCD imaging system. The electroluminescence imaging technique is thus used to highlight the defects in the sensed image.
How do mechanical defects affect the quality of solar cells?
Solar cells or photovoltaic systems have been extensively used to convert renewable solar energy to generate electricity, and the quality of solar cells is crucial in the electricity-generating process. Mechanical defects such as cracks and pinholes affect the quality and productivity of solar cells.
Can image processing improve solar cell defect detection efficiency?
Image processing was applied to detect the defects automatically which included black pieces, fragmentations, broken grids and cracks. The defects were classified, and then, the locations of defects were marked. Their experimental results showed that their system could improve the defect detection’s efficiency on solar cell products.
