Inkjet Printing of Isolation Layers for Back-Contacted Silicon-Heterojunction Solar Cells
In this work the potential of inkjet printing for the deposition of the isolation layer with photoresists or other polymeric fluids is evaluated. Challenges are the required placement precision and the feature size. In order to produce circular openings of the order 10 μm, the drop formation has to be optimized, and the ink spreading on both surfaces - on the aluminum emitter and on the silicon wafer substrate - have to be controlled.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
