The solar cell sorting method comprises the following steps: establishing a database of the colors and the reflectances of the solar cells, wherein the reflectances of the solar cells in the database under the light source with the preset wavelength are in one-to-one correspondence with the colors of the solar cells; obtaining the reflectivity of the solar cells to be sorted under a light
This method sorts by comparing the histograms and calculating the similarity. The sorting results are very accurate, and most of the solar cells to be sorted can be allocated to the appropriate gear; and there is no difference between the solar cells to be sorted The color of the color is close to the critical value of the two gears, which causes the problem of difficult sorting.
The solar cell color difference sorting method comprises the steps of collecting images of to-be-sorted cells; dividing the images into a plurality of subimages which are crossed vertically and horizontally, calculating an LAB three-component average value of each subimage and color difference values between the subimages, and finding out the maximal color difference value of

The color difference still satisfies the quality of solar cells as it fails to reduce the photoelectric conversion efficiency of the solar cell but affects the product appearance. Generally, a solar panel consists of many solar cells. If these solar cells have large color differences that are not in the same color category, the panel color will be inconsistent, affecting the quality of the
