3D Printer Based Slot‐Die Coater as a Lab‐to‐Fab Translation Tool for Solution‐Processed Solar Cells

Abstract

A 3D printer based slot-die coater is developed as a lab-to-fab translation tool for solution-processed solar cells. The modified 3D printer is used to develop the printing process for potential use in large scale roll-to-roll production. Fabrication of a 47.3 cm2 organic solar cell module with 4.56% efficiency and printed perovskite solar cells with 11.6% efficiency are demonstrated.
