You are here  Organic electronics research replaces costly ITO
Dan Rogers - 08 Apr 2010  US research into organic electronics
has produced a replacement for indium tin oxide (ITO).  The
plastic transistor tested at Princeton shows current passing
through in greenThe research team at Princeton University in New
Jersey, US, has developed a suitably conductive layer for
plastic electronics, such as organic solar cells, that could
challenge the performance of ITO.  ITO is currently used as a
means of conducting electrical charge in plastic electronic
devices, such as displays and photovoltaics (PVs), but its
brittleness and high cost do not compliment the selling points
of flexible, cheap-to-print organic electronics.   Associate
professor of chemical engineering and lead researcher Lynn Loo
says: 'While [plastic electronic materials like] PEDOT:PSS are
fantastic for production, they lose conductivity by several
orders of magnitude.  'What we've come up with is a way to
manipulate the structure of these material
