There’s a lot of confusion between different grade solar cells. Any deviation is often graded as B, however a correct classification is. .
Grade A cellsare simply without any visible defects, and the electrical data are in spec. The specifications of the cells can be measured with cell. .
A Grade C solar cell has visible defects, and the electrical data are off-spec. All solar cells with defects worse than Grade B can be classified as Grade C. Or A solar cell can be graded as C. .
Grade B cells have visible but tiny defects, and the electrical data are in spec. The following visible defects are common: 1. Slight bendof 2.0mm – 2.5mm 2. Color deviation, Visible yellow area takes more than 1/4 area of total on. .
A Grade D solar cell is broken and can not be cut in smaller cells. There’s not much you can do with these..

There’s a lot of confusion between different grade solar cells. Any deviation is often graded as B, however a correct classification is complicated because there are dozens of different solar cell defects that can occur. This post is a first attempt to design a classification (A, B, C, D) of solar cells, and is a summary of a more in. .
