Project description:

   Monocrystalline silicon solar cell is obviously better than polycrystalline silicon solar cell in efficiency due to its complete internal crystal structure. However, the internal impurities and crystal defects of monocrystalline silicon have a serious impact on the efficiency of solar cells.

  Defect types:

    Hidden cracks, foggy blackening, sucker prints, graphite boat prints, concentric circles, virtual prints, dirt, etc.

                                                                                                                               Original  picture                                                                              Detection  picture
