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, such as in perovskite solar cell.

    MSK-USP-06 is an automatic ultrasonic spray pyrolysis (USP) equipment with Stainless Steel Chamber and Molten Tin-Bath Heater. Three compressive gas spray heads are included to enable multilayer film coating. Compares to the regular SS hot plate, the tin-bath heater provides uniform and stable heating to the substrate during the coating process. The SS304 chamber ensures a clean and healthy atmosphere suitable for the most demanding experimental requirements. A software is included for the automation of spray head movement and dispensing rate. A positive displacement pump controlled by a stepper motor is used to dispense solution as per requirement. The ultrasonic spray head ejects fine atmoized solution on substrate and its movement is controlled by the stepper motor driven linear stages in X and Y direction to ensure uniform coating. The spray pattern and velocity can be adjusted by changing the compressed gas pressure at the nozzle.

Power Input	•  Single phase 208 - 240 VAC,  50/60 Hz      •  Please order a 1500 W transformer for running the machine         only at 110 V      •  Please order a 3000 W transformer for running the machine         and the air compressor at 110 V      •  Actuator: Stepper motor, 24 VDC
Chamber Size	•  The SS304 chamber provides a working space 700mm x          700mm x800mm
Dispenser	•  Dispensing unit capacity: 50 mL & 250 mL (two containers         included) container      •  Container dispensing rate: 1-10 mL / min adjustable via         software      •  Syringe pump dispensing rate: 20 μL/min - 10 mL/min         adjustable via software
Sprayers	•  Three compressive gas spray heads are included to enable          multilayer film coating      •  Each spray head can be used to spray a different type of         solution.  A masking disc inside the chamber (flip shutter),         which can be moved from outside using a knob/lever, is used         to prevent the substrate from being exposed to droplets during         spray head changeover.      •  Producing a fine spray of droplets of 50 microns average size      •  Fluid viscosity range: 1 - 50 mPa·s (cP)      •  Sprayer traverse:  X - Y 200 mm max      •  Drive speed X axis: 10-800 mm / sec      •  Drive speed Y axis:  1-12 mm / sec     Note: you will need to use inert gas (~3 psi) for atomizing     the solution and shape the spray pattern. Ultrasonic     sprayers are available upon request. Additional cost will     apply.
Pressure Regulator & Gauge	•  Pressure regulator with digital gauge is installed on the           machine  for precise air pressure control.      •  Recommended pressure for gas-assisted spray of aqueous         solution: ~3 psi
Vacuum Pump	•  156 L/m Double Stage Rotary Vane Vacuum Pump with          Exhaust Filter - EQ-FYP-Pump is included in the package      •  Normal base pressure range 500~600 milibar      •  The vacuum pump is installed in the bottom cabinet
Molten Tin-bath Heater	•  Dimension: 150 mm × 150 mm      •  Max temperature: 500°C
Software	•  The system controller box is connected to laptop or Surface         Pro via RS232 port and USB adapter      •  Centralized software control of dispensing rate, X-Y stage         movement, solution loading and draining      •  All of the process parameters can be saved as a user process         and retrieved later for analysis or re-run      •  One brand new laptop computer or one Microsoft Surface          Pro with pre-installed software is included.
