Photovoltaic Devices: High Performance Roll‐to‐Roll Produced Fullerene‐Free Organic Photovoltaic Devices via Temperature‐Controlled Slot Die Coating (Adv. Funct. Mater. 6/2019)

Abstract

In article number 1805825, Seok-In Na, Doojin Vak, and co-workers develop hot slot die deposition using a 3D printing platform and the optimized parameters are translated to the roll-to-roll deposition system to produce high performance flexible organic solar cells with a non-fullerene-based formulation. The key approach of this work is heating both the slot die head and the substrate during the deposition process.
