Conductive ink for digital printing: low-Ohms and ink-jettable
The photo above shows an organic photovoltaic cell with connectivity implemented in the DuPont PE410 inkjet silver ink; the cell was developed at the Holst Centre (Eindhoven, Netherlands)
PE410 enables rapid prototyping and a smooth transition from “lab to fab” with the versatility to scale up to industrial high-volume inkjet print heads and machines. This allows circuit designers to immediately test a new design, quickly make necessary edits, and, due to reduced silver laydown, save on material costs. The technology also can be adapted to non-planar printing, enabling a series of new and emerging applications.
“Based on industry benchmarks, we find DuPont’s new conductive inkjet ink to provide the best combination of important properties available among competitive products,” said Jeroen van den Brand, program director, Holst Centre. “When considering the low sintering temperature, conductivity, adhesion, print head stability, fine line capability and substrate compatibility, DuPont’s solution is the leader.”
