Conductive Inks Give Military Access to Cheap, Ready to Use Solar With Just an Ink Jet Printer
Fancy that, the military getting the cutting-edge technology before the rest of society. This article explains the phenomenal solar technology the U.S. military will have at its disposal.


The military is often at the forefront of renewable energy technology. That’s because fossil fuels are costly, dangerous and difficult to transport. They create a heat signature that is easily located by enemies and require large convoys for keeping the troops powered. And they are proving ever more difficult and costly to secure.

So, it was not a surprise when Renewable Energy World reported that the Air Force Research Laboratory (AFRL) has been working with the Pennsylvania NanoMaterials Commercialization Center and Plextronics to develop a conductive ink that allows the use of an ink-jet printer to make printed organic photovoltaic solar cell panels on very thin, flexible surfaces.

1. Cool

I can't wait until it is mass produced for consumers. It will revolutionize the developing world and the suburbs in the developed world. Supposedly the stuff is 10x cheaper than silicon cells per square meter. No idea about the efficiency though. I just read it is only 5%.

3. 14% efficiency and production cost of $0.36 / watt plus installation
Those are from NanoSolar. There is another company that has developed a novel way of installing them that cuts the installation costs dramatically - Solyndra. Check out their websites.

I've heard of nanosolar, but didn't know they were at 14%.

I think a huge benefit of plexcore is that you can print it on location and avoid shipping, which will hopefully help in rural places in Asia or Africa.

2. Actually they are a Johnny-Come-Lately
Check out NanoSolar if you want to buy some yourself.

5. No, this is different. Plexcore® is organic. NanoSolar is CIGS

Plexcore® Products for Printed Electronics

http://engineeringtv.com/blogs/etv/archive/2008/08/27/printed-solar-power.aspx">Watch Engineering TV's interview with Plextronics about our printed solar technology and latest product release, Plexcore PV.

Plexcore® polymers and printable inks are the key ingredients in the formation of high-quality organic layers. Whether for next-generation, power efficient displays, low-cost, easily available plastic solar cells or item-level radio-frequency tags, Plexcore® polymers and inks deliver the performance to drive the adoption of these devices.



From a technology standpoint, all printed electronic applications require one or more conductive layers that can be integrated with organic semiconductors, dielectrics and other conductive films. Plexcore® OC is a solution-processable, organic conductive ink that can serve multiple functions in printed electronic devices. Plexcore® OC inks are ideal for integration into various printed electronic devices because they can be tailored to the particular needs of a device. Additionally, Plexcore® OC inks are chemically and thermally stable, making them easy to use in the production environment.

For the commercialization of low-cost electronics, silicon semiconductors must be replaced with more cost effective materials, from both a raw materials and production process standpoint. Plexcore® OS, an organic semiconductor, is the technology enabling a revolutionary class of low-cost electronics—from printed RFID tags for supply chain management and product authentication to printed backplanes for advertising and consumer electronics.


NanoSolar does seem to have them beat on efficiency though.

llecker@plextronics.com

Pittsburgh, PA, October 6, 2008 – Plextronics, Inc. — an international technology company that specializes in printed solar, lighting and other electronics — announced today that it has secured $1.2 million in funding as part of the 2009 Defense Appropriations Bill Continuing Resolution (H.R. 2638) that was signed into law on September 30. The award is a new contract for the company to develop flexible and light-weight printed electronics for the United States Military, including products and applications such as flexible solar panels for tent tops, solar-powered foldable blankets and helmet-mounted panels, printed lighting, flexible displays and printed circuitry.

According to Andy Hannah, president and CEO of Plextronics, this award is another step closer to the broad commercialization of printed electronics. "We're all seeing a worldwide focus on new sources of efficient, renewable energy, and there is no question that printable solar and lighting technology is a key part of that mission," Hannah said. "This project will enable us to continue to work with the military to develop applications and products that will make life in the field better for our soldiers."
