Lab Desktop Ultrasonic Spray Pyrolysis Equipment or Mist CVD Used to Prepare Thin Film And Solar Cells of Perovskite


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 cells.


MSK-USP-02 is a desktop ultrasonic spray pyrolysis (USP) equipment or called Mist CVD where parameters like dispensing rate of the solution and speed of spray head movement are precisely controlled by a software interface. A positive displacement pump controlled by a stepper motor is used to dispense solution as per requirement. The ultrasonic spray head provides thin-film coating 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 air pressure at the nozzle. The temperature of the substrate heater plate is controlled independently through a dedicated controller.
