http://www.strategyr.com/Organic_Electronics_Market_Report.asp
2010 to 2020 Market Size
IDTechEx find that the market for printed and thin film electronics will be $1.92
Billion in 2010. Of the total market in 2010, 35% will be printed.
Initially photovoltaics, OLED and e-paper displays grow rapidly, followed by
thin film transistor circuits, sensors and batteries. By 2020 the market will be
worth $55.1 Billion, with 71% printed and 60% on flexible substrates.

66. Profile of Research in INEO
The proposal of INEO is to develop science and technology for strategic areas, as
Biotechnology, Health and Energy.
i) synthesis and chemical modification of molecules (small molecules and polymers);
ii) methods to prepare organized organic thin films with enhanced physicochemical
properties;
iii) advanced methods to explore interfacial phenomena;
iv) analysis of electrical and optical properties of thin organic films;
v) molecular dynamics and conformational properties obtained with high-resolution
NMR combined with thermal analysis and X-ray diffraction and scattering;
vi) theoretical approaches to determine the electronic and conformational properties
of molecules as well as models for transport in optoelectronic devices;
vii) technological development of electronic and optoelectronic devices (OLEDs,
OPVs, Transistors, etc.)
