Soft Electronics –
Reality or Pipe-Dream?
1947 – the 1st transistor
(Ge point contact)
1948 – the 1st junction
A revolution in functional materials for high technology?
Sov and Alan MacDairmid
organic solar cells
A thin film conducting
polymer transistor and
“soft-circuitry” – arrays
of these transistors on
a flexible polymer sheet
Light emitting polymer
displays – thin, flexible
screens with 180˚ view
Plus “organic molecular crystals” like the oligo-acenes
A melanin sensor
EDX Scan Line way) fuel this revolution?
50nm2. Novel Routes to Synthetic Conducting Polymers (Ion Implantation)
CHEAP, CONDUCTING PLASTICS –
FROM CONVENTIONAL INSULATING PLASTICS?
Current WORLD RECORD ~5% (PCE)
(c.f. Commercial Silicon cells ~ 15%)
nano-crystals in a
This cell produces a WHOPPING 20mA

A carbon nanotube field –
potential solar cell material
A nanostructured titania support/electrode
We at UQ Physics are trying to do our bit:
- functional biomaterials
- plastic solar cells
- new (cheap), patternable synthetic conducting polymers
