Optomec’s Aerosol Jet® solution is a fine-feature material deposition system used to directly print functional electronic circuitry and components onto low- temperature, non-planar substrates. The system is quickly gaining traction in Photovoltaics, both as a near-term production solution that can increase Solar Cell efficiencies by >1% absolute (ie: 5-10% relative), and as an enabling technology for next-generation ultra-high efficiency cell architectures. Aerosol Jet printing is a breakthrough additive manufacturing technology that is an emerging replacement for traditional thick-film processes like screenprint, photolithography and micro-dispensing, as well being far more capable than inkjet. The patented Aerosol Jet process utilizes an innovative aerodynamic focusing technology to produce electronic and physical structures with circuit features as small as 5 microns, and can also produce wide area conformal coatings. The broad functionality of Aerosol Jet technology addresses numerous elements of the Symposia’s strategic technical topics. Optomec decided to submit an abstract which paints a broad overview of the Aerosol Jet disruptive and novel manufacturing technology, addressing a wide range of applications including the “Carbon Nanotube – Innovation” and “Energy Storage – Innovation” topics. To address a specific Symposia topic, Optomec’s abstract drills down into specific manufacturability and benefits for the “High-Efficiency PV Conversion – Innovation” topic.
