MSK-PSC-DSM3030 Sheet-to-Sheet Slot Die Coater with 300 mm Coating Width, Marble Vacuum Chuck, and Air Knife for Perovskite Solar Cell Thin Films
The MSK-PSC-DSM3030 is engineered for the precise deposition of ultrathin perovskite layers on both rigid and flexible substrates, addressing the challenges of uniform thin film coating in solar cell fabrication. It supports substrates such as ITO and FTO with a maximum thickness under 3.2 mm, including flexible PET-based films. The system is optimized for sheet-to-sheet processing with a maximum coating area of 300 mm by 300 mm.
This coater utilizes a slot die head with a 300 mm coating width, incorporating three interchangeable shims (0.02, 0.04, and 0.06 mm thickness) to adjust the coating thickness, which can reach a minimum of approximately 2 µm depending on slurry viscosity. The super flat marble vacuum chuck ensures substrate flatness with surface accuracy within 5 µm, securing the substrate during coating. An air knife is integrated to assist in film uniformity and drying control.
Key Features
- 300 mm wide slot die head with three shim thickness options for precise film thickness control.
- Super flat marble vacuum chuck with ≤5 µm surface accuracy and four vacuum holes for secure substrate holding.
- Adjustable coating speed up to 100 mm/s via a 4″ color touchscreen control panel.
- Compatible with rigid substrates (ITO, FTO) and flexible substrates (ITO/FTO on PET) up to 3.2 mm thick.
- Syringe pump feeding range from 0.1 to 500 µL/s with a standard 10 mL syringe volume.
- Supports slurry viscosities from 1 to 1000 cps for versatile coating materials.
- CE certified with optional NRTL or CSA certification available.

Typical Applications
This coater is specifically suited for fabricating ultrathin perovskite layers in solar cell research and production. It is also applicable for coating other thin films requiring high uniformity on both rigid and flexible substrates, such as transparent conductive oxides and functional layers in optoelectronic devices.
Configuration & Operating Notes
The system includes a slot die head with three standard shims; additional shim thicknesses and slot die heads with different open-mouth widths can be supplied upon request to tailor coating widths and thicknesses. The vacuum pump for the marble chuck is externally connected and not included as standard. Operators should ensure proper vacuum connection and substrate cleaning before coating. The 4″ touchscreen panel allows intuitive adjustment of coating parameters including speed, temperature, and syringe pump rate. Optional certifications such as NRTL or CSA can be provided at extra cost.
