PRINTED ELECTRONICS

The New Chemistry
of Printed Electronics
Printed electronics enable electronic processes to be
directly ‘printed’ onto substrates for a variety of uses. The
market will see rapid growth over the next few years.
Dr Peter Harrop, Chairman, of IDTechEx discusses the
materials that will help move the market further ahead.
P
rinted and potentially printed electronics and
electrics are conveniently referred to as printed
electronics or rather misleadingly plastic or organic
electronics. Since this is the future of lighting, signage,
electronic displays, sensors, batteries for electronics and even
photovoltaics (solar cells), few dispute that it will rise to the
order of $300 billion dollars in twenty years from now.
IDTechEx has closely analysed this huge new opportunity for the
fine chemicals, electronics and process industries. The growth in
the next four years is enough to attract companies of all sizes,
particularly with many unsolved technical problems that can lead
to premium priced products for those that are successful.
Few elements have been involved in manufacturing so far but
that is now changing with the first sales of printed Organic Light
Emitting Diode displays, a variety of screen printed and thin film
manganese dioxide zinc, lithium ion and lithium polymer
batteries, ink jet printed copper indium gallium diselenide CIGS
photovoltaics and Dye Sensitised Solar Cells DSSC, the latter
based on titanium dioxide with ruthenium based organic dye.
Specially developed ink jet printing has now overtaken screen but
no one printing technology will ever do everything.
Chemicals, morphologies and processes
The printed electronic market has now become challenging with
a huge range of new chemicals; nanotechnology and printing
technology brought to bear with thin film deposition techniques
other than printing tailored to play a part. Totally new product
concepts are emerging, from the cloak of invisibility to edible
electronics, stretchable electronics and electronics as art.
Disposable labels and other human interfaces will employ far
more of the human senses to give almost unlimited information,
entertainment, brand enhancement and brand protection.
