Printed electronics turn to gold for novel applications

NanoMarkets released “Printed Gold: Gold Inks and Pastes Market — 2011,” finding that “novel” nanoink applications will represent gold’s greatest opportunities in the electronics and solar technology sectors.

September 19, 2011 — Industry analyst firm NanoMarkets released ?Printed Gold: Gold Inks and Pastes Market — 2011,? finding that ?novel? nanoink applications will represent gold?s greatest opportunities in the electronics and solar technology sectors.

Gold ?nanopastes? could significantly lower costs in traditional thick-film processing, shows NanoMarket?s report. Gold pastes are used in wire bonding to package semiconductors, brazing, and other applications.

New nano-gold inks will be used to make better micro electro mechanical systems (MEMS) and sensors, data storage products, memory chips, photovoltaics, and more. Thin layers of gold nanoparticles could greatly increase storage capacity on CDs/DVDs. Gold nanorods could enhance optical storage. Printed gold will also serve sensor manufacturers that shift from gold plating to printed gold, especially for large area sensors.

Printed gold nanoparticle layers have been shown to boost solar cell efficiency, indicating gold?s ?growing role in PV in recent years,? NanoMarkets notes. Printed Electronics USA, an event hosted by IDTechEx November 30-December 1 in Santa Clara, CA, will include 14 presentations on printed materials for photovoltaics. Expect photovoltaics to be the single largest sector of printed electronics in 2021, IDTechEx predicts, with that including flexible and stretchable photovoltaics for electric vehicles, and solar charging stations for these cars.

Electronics and PV applications will use 13.7 tonnes of gold inks and pastes by 2016. According to an IDTechEx report, “Printed, Organic  & Flexible Electronics Forecasts, Players & Opportunities 2011-2021,” the printed electronics business is set to be over $55 billion in ten years and around $300 billion in twenty years as the familiar exponential kicks in.

Gold pastes will benefit commercially from the regulatory requirements for lead-free electronics that have gone into force in both Europe and the U.S.  In addition, there are increasing concerns by regulators with regard to nanosilver and printed nanogold may serve as a good substitute in some applications. Printed Electronics USA will reflect the widening government support for printed electronics, via university and government research funding, military development, and electric vehicle (EV) promotion. The US Army will give 2 presentations at the conference.

?Printed Gold: Gold Inks and Pastes Market — 2011? provides eight-year projections (both volume and value) of all major applications in which gold inks and pastes are, or will be, used.  These projections also include a breakout by the kind of printing process used:  jetting, screen or flexo/grave.  Among the firms discussed in this report are: Bellman-Melcor, Bosch, Brazetec, DuPont, Ercon, ESL Electroscience, Hitachi, IBM, Indium Corporation, Johnson Matthey, Krohn, Samsung and Umicore.  The report also includes an analysis of research taking place at Berkeley, ETH, Rensselaer, UCLA, University of Melbourne, University of Tokyo, VTT and other major research centers.
