Title:
ULTRASONIC NOZZLE FOR ANTI-SOLVENT ASSISTED SPRAY COATING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/231365
Kind Code:
A3
Abstract:
The invention is an ultrasonic nozzle (10) to be used in a method for performing film forming process at a single point and high speed by means of using spray coating together with anti-solvent vapor and carrier gas which is a known method used for forming thin polycrystalline films, characterized in that; lateral spaces (102) on both sides where the anti-solvent vapor and/or the carrier gas entry is performed, an axial clearance (101) at its axis where perovskite solution (103) and the pressurized nitrogen gas are sprayed onto the surface to be coated (A), an air cap (104) which enables to transfer the anti-solvent vapor and the carrier gas coming from the lateral space (102) onto the surface to be coated (A) in a conical angular manner, guide channels (105) which guide the anti-solvent vapor and the carrier gas included in the air cap (104) in an angular manner onto the surface to be coated (A).
