High-precision slot die coating equipment
Slot-die coating is a coating technique in which a solution is delivered onto a substrate via a narrow slot positioned close to the surface. The slot-die has a high aspect ratio outlet controlling the final delivery of the coating liquid onto the substrate. This results in the continuous production of a wide layer of coated material on the substrate, with adjustable width depending on the dimensions of the slot-die outlet. By closely controlling the rate of solution deposition and the relative speed of the substrate, slot-die coating affords thin material coatings with easily controllable thicknesses in the range of 10 nanometers to hundreds of micrometers after evaporation of the precursor solvent.

DaZheng has achieved the liquid-phase coating preparation of continuous four-layer nano-scale thin films and the stable production of perovskite solar cells.
Application of high precision slit coating equipment.
It is suitable for the coating of substrates such as organic solar cells and perovskite solar cells, non-continuous substrates such as LCD glass substrate, also used in optical film (brightness enhancement film, hardcoat, polarizing film, diffusion film, etc.), OLED coating, etc.
