Process flow

  • 1. The texturing process

    The purpose of texturing is to form microstructures on the surface of silicon wafer (suede) and reduce the surface recombination of silicon wafer.

  • 2. The diffusion process

    The purpose of diffusion is to form the PN junction on the surface of silicon wafer, which is the heart of the solar cells.

  • 3. The etching process

    The purpose of etching is to remove the PN junction on the back and around the silicon wafer, and achieve the anti-PID function of the module through surface oxidation.

  • 4. The PECVD process

    The purpose of PECVD is to form an anti-reflection film on the front of the silicon wafer, reduce the reflection of light, increase the absorption of light, and passivate the surface of the silicon wafer.

  • 5. The printing process

    The purpose of screen printing is to form the electrodes of the cells, and the sintering process makes an ohmic contact between the metal electrode and the silicon.

  • 6. The inspection process

    The cells with similar efficiency and color are sorted out and packaged together.
