HJT Tandem Perovskite Coating Production Line

This equipment is specially designed for the HJT tandem perovskite coating production line, capable of coating silicon wafer sizes of 182mm*105mm, while also compatible with functional layer coating of 210mm*105mm.

This coating equipment system includes: Coater (with solution supply system), environmental enclosure (with organic solvent treatment device), silicon wafer handling robot mechanism (with cassette lift and transfer mechanism), and electrical control unit.

This system uses a fully automatic mechanical transfer method to place the substrate onto the coating platform and position it for fixation. The coating die, controlled by a linear motor, applies the functional solution. The sample then undergoes IR infrared heating for pre-curing and drying, and finally the coated sample is automatically transferred to a cassette for unloading.

This coating system is the first mass-production-takt, fully automatic crystalline silicon tandem perovskite coating production line in China.
