Flexible Connections for Flexible Solar Cells
Aug 1, 2008 — While today’s solar cells are costly and made out of silicon, tomorrow’s may be made out of plastic and be very inexpensive. However, these polymer solar cells must be flexible. That’s a problem for the device’s cathode and anode. These electrical connectors must be transparent, conductive, flexible and compatible with plastics processing — a challenging combination. On the left is the structure of a polymer solar cell with a flexible anode. The anode consists of the PEDOT PH500 and...
Flexible Display Flaw Fixed
WEST LAFAYETTE, Ind., July 28, 2008 -- A critical flaw to producing transistors for flexible displays from networks of carbon nanotubes -- namely that the metallic nanotubes in the network can cause short circuits -- has been overcome by changing the way such nanotube circuits are made....
Cu Nanowires Create Displays
CHAMPAIGN, Ill., April 30, 2008 -- Copper (Cu) nanowires grown at low temperatures and catalyst-free could serve as interconnects in electronic device fabrication and as electron emitters in a very thin flat panel display known as a field emission display. “We can grow forests of...
Trumpf Acquires Laser Plastic Welding, Soldering Technology
Feb 14, 2008 — Trumpf Laser GmbH + Co. KG of Ditzingen, Germany, announced yesterday that it has acquired the laser plastic welding and selective laser soldering capabilities of Fisba Optik AG for an undisclosed amount, effective Feb. 1. Trumpf said the...
FETs Fabbed with Fullerene
ATLANTA, Dec. 3, 2007 -- High-performance field-effect transistors (FETs) have been fabricated at room temperature using thin films of carbon 60 (C60), an organic semiconductor material also known as fullerene. The new transistors won't replace silicon-based CMOS chips but...
Optical Device to Reveal Adult Brain Plasticity
HOUSTON, April 30, 2007 -- It may be easy to change your mind, but your brain? Using a new optical imaging device that quickly maps the visual cortex, researchers hope to reveal how "plastic" or adjustable, adult brains really are. Valery Kalatsky, assistant professor of...
Mass-Marketed OLEDs Could Power Lighting Revolution
BATH, England, April 19, 2007 -- A thin film of plastic that conducts electricity and produces solar power could be the basis for a revolution in the way we light our homes and design clothes. An international research project has begun that could help bring to mass-market organic...
Plastic With Adjustable Conductivity Developed
AUSTIN, Texas, April 9, 2007 -- A plastic has been modified so its ability to carry an electrical current can be altered during manufacturing to meet the needs of future electronic devices, such as military camouflage that changes colors, foldable electronic displays and medical...
Plextronics Gets $750K to Develop Technology for Organic Solar Cells
Jan 23, 2007 — Plextronics, a Pittsburgh-based developer of active-layer technology for printed electronic devices, announced it has received $750,000 in funding from the Sustainable Energy Fund of Central Eastern Pennsylvania to further develop Plexcore PV...
Flexible, Flippable Plastic Semiconductor Created
MADISON, Wisc., July 19, 2006 -- A newly invented thin-film semiconductor fabrication process can be used to add sensing, computing and imaging capabilities to a wide array of materials, including plastic and glass, its creators said, opening a wide range of possibilities for...
Painting Nanowires Yields High-Speed Circuits
Jul 1, 2005 — The production of circuits and processors from silicon substrates is expensive, and the required high-temperature fabrication process is not always compatible with a variety of materials. Researchers at Harvard University in Cambridge, Mass., have...
UCSD Team Transfers Silicon Crystal Sensor Properties to Plastic
May 2, 2003 — SAN DIEGO, Calif., May 2 -- Researchers at the University of California, San Diego (UCSD), have discovered how to transfer the optical properties of silicon crystal sensors to plastic, an achievement they say could lead to the development of...
Sumita Optical Glass Inc.
Jan 1, 2003 — Sumita Optical Glass Inc. developed its K-PG325 Super Vidron optical glass to replace the less durable plastic now used in optical molded parts. This material can be precision-molded at approximately 325 °C, making it suitable for use with a wide...
