Slot‐Die Coating for Scalable Fabrication of Perovskite Solar Cells

Tapemark Engineer Mike Rothaupt explains what slot die coating is and how it helps us coat

In the slot-die coating process, the liquid enters a fixed gap slot encompassed by two precisely machined dies and exits the die to establish contact
