  • Chain tufting machine
    In order to reduce the mechanical damage caused by the cutting process of the silicon wafer, the chain type velvet machine can enhance the absorption of light on the surface. The chain - making machine is the industry 's advanced equipment for removing the damage layer. Its features are as follows:

    >> The removal of the damage layer and the surface texture are completed in the same reaction tank
    >> Optimized design of hydrodynamic design, good uniformity of the surface
    >>Equipped with MANZ automatic feeding equipment
    >> Integrated online weighing system to realize on line monitoring of key process parameters
  • Chain PSG removal and pn- junction etching machine
    Chain etching machine at the same time to remove the PSG and the back of the pn- junction, its unique process design can not only ensure a good pn- junction etching (isolation), but also to remove the back of the pn- junction, to achieve the purpose of passivation of the back. Its features are as follows:

    >> PSG removal and PN junction isolation on the same device
    >> Back passivation process
    >> Single crystal and polycrystal etching
    >> Equipped with MANZ automatic feeding equipment
  • Diffusion furnace
    Diffusion furnace can meet the production needs of various spectral characteristics of solar cells. The automatic feeding and discharging system can reduce the pollution to the minimum and ensure the reproducibility of the diffusion results.
    >> Double sided, single side diffusion
    >> Automatic quartz boat transmission system, high equipment utilization
    >>Equipped with J& R automatic loading and unloading system

    >> Advanced deposition time feedback system to reduce the impact of graphite boat
  • screen printing
    Double track screen printing line modular degree is high, convenient and more need to choose configuration. The optical debris detection system automatically detects the mechanical damage of the silicon wafer and removes the silicon wafer. After printing, the system can detect the printing quality of the front side, the back main grid and the back electric field.
    >> High productivity
    >> Low fragmentation rate
    >> Equipped with online printing quality inspection module
    >> Automatic detecting backside coated silicon wafer
    >> With two printing or two printing
  • Color and efficiency sorter
    Using the online high precision electrical performance tester, A+A+A+ spectra meet the IEC60904-9 Ed.2.0 standard. The classification of the final production cell of the tester and color division and module.
  • Wafer inspection equipment
    WIS silicon automatic sorting machine equipped with a variety of types of detection modules, such as appearance, size, silicon chip characteristics, such as crack and PL. The classification rules can be defined according to the results of inspection and measurement, and the results can be recorded and output in order to follow up and manage.
  • Sintering furnace
    The sintering furnace is used to burn organic residues without sintering to form metal contacts to achieve a more optimized ohmic contact.
    >> High heating rate and cooling rate to control the excellent process
    >> Short wave infrared combined with continuous functional monitoring to ensure the consistency of the process environment
    >> Optimization of mesh belt design to reduce its influence on sintering quality
