EIKOS SELECTED TO PRESENT PHOTOVOLTAICS STUDY USING TRANSPARENT CARBON NANOTUBE ELECTRODES AT ORGANIC ELECTRONICS CONFERENCE
Eikos Senior Engineer Dr. David Britz will present
the research at the Organic Electronics Conference and Exhibition 2006 in
Using Eikos Invisicon® carbon nanotube conductive coatings, NREL/Eikos created organic solar cell structures that achieved an efficiency of 2.6% -- making them competitive with cells utilizing Indium Tin Oxide (ITO) transparent conductors. Additionally, Invisicon® coatings that replaced both ITO and PolyEthyleneDiOxyThiophene (PEDOT) produced cells with 1.5% efficiency, and further reduce manufacturing complexity and costs. Organic photovoltaics (OPVs), especially those enabled by carbon nanotube transparent electrodes, are an attractive alternative to traditional silicon-based solar cells because of their low cost, flexibility, and light weight.
Under the same DOE research program, the NREL/Eikos team produced the world’s first thin-film Copper Indium Gallium diSelenide (CIGS) solar cell incorporating CNTs. Using Invisicon® transparent coatings instead of doped Zinc Oxide, a significant 13% energy conversion efficiency was achieved.
Eikos, Inc. is a developer and
manufacturer of highly transparent carbon nanotube inks and conductive coatings
for use in solar cells, flat panel displays, OLED lighting, smart windows and
other established markets. Eikos’ patented Invisicon® transparent
conductors (‘nanowires’) will enable high volume, low cost, and environmentally
friendly production of a flexible and more durable conductive coating
technology that will displace Indium Tin Oxide (ITO), Zinc Oxide, PEDOT/PSS,
and other transparent conductors. A privately held company headquartered
