Ultrasonic Spray pyrolysis is a process in which a thin film is deposited by spraying a solution on a heated surface, where the constituent reacts to form a chemical compound. The process is particularly useful for the deposition of oxides and has long been a production method for applying a transparent electrical conductor of Tin oxide (SnO2) or Stannic oxide to a glass substrate. Now, this technique is increasingly used to prepare perovskite thin film and battery electrode.
MSK-SP-04-HT is a high-throughput spray pyrolysis system, which carries three types of solutions and coats different combinations of composition as the program to 18 mm dia. substrate up to 36 positions. The coating chamber is vacuumable which allows spray pyrolysis under controlled atmosphere. This is smart equipment to explore new generation material at a faster speed for battery electrodes and perovskite solar cells.

( Pic 3) (PiC 1 ) Pic 2 (Pic. 3)
Syringe pump	Four Syringe pumps are included. Three for the solution to be mixed and coated and one for cleaning by DI water. Standard syringe capacity 60 ml other capacity is available  Line speed range 1 µm/min---120 mm/min adjustable Accuracy ±0.5%when >30% FS Control: The syringe pumps are controlled by either self digital control panel or main touch screen control panel.
Solution Mixing	Three types of solutions will be mixed and dispersed in the small container before spraying. Container size: Φ25x100mm H~ 50ml Blade stirring Speed: 120 RPM
Vacuum Chamber	The chamber is made of stainless steel Chamber size: 650 x 600 x 500mm Max. Vacuum limit: 20 torrs by mechanical pump, which is included ( click Pic below right to see specs) One dual-stage mechanical pump is included
Processing Platform	The precision X-Y-Z travel mechanism is built inside the vacuum chamber, which will carry the spray nozzle to the desired position for coating locally. Travel Distance: ( X-Y axis ) 200 mm Max Z-axis: 60 mm Max. Travel Speed: 1mm/s - 12mm/s One set of substrate plates with a 36 cylinder mask is built in the bottom of the chamber.
