MSK-AFA-SD200-CDH Roll-to-Roll Slot Die Coater for Continuous Multi-Layer Coating of Flexible Perovskite Solar Cells
The MSK-AFA-SD200-CDH is engineered to address the precise coating requirements of flexible perovskite solar cells, enabling continuous deposition of multiple functional layers including electron transport layer (ETL), perovskite active layer, hole transport layer (HTL), and conductive layers. This roll-to-roll slot die coater facilitates high uniformity and repeatability in coating thin films on flexible substrates, essential for scalable solar cell manufacturing.
The system integrates a servo motor-driven main drive with a steel roller of 80 mm diameter, supporting substrate widths up to 180 mm and coating widths adjustable between 50 and 160 mm via interchangeable shims. Coating thickness for perovskite solar cells is typically maintained between 30 and 50 micrometers (wet film), with flexibility to extend from 3 to 500 micrometers for other applications. The coating speed ranges from 0.1 to 2 meters per minute, allowing process optimization for different materials and layer requirements.
Key Features
- Continuous roll-to-roll coating mode optimized for flexible perovskite solar cell layers.
- Slot die coating width adjustable from 50 to 160 mm using customer-specified shims.
- Integrated convection oven with electrical heating up to 130°C for drying coated films.
- Four customized syringe pumps with step motor drivers for precise fluid delivery (0.4–60 mL/min).
- Tension control system with swing roller and precise valve adjustment, supporting up to 120 N tension force.
- Guiding and winding/unwinding rollers designed for substrate alignment and roll handling up to 400 mm diameter.
- Servo motor main drive ensuring stable coating speed and substrate transport.
