ORGANIC ELECTRONICS
Organic electronics,is a branch of materials science dealing with electrically-conductive polymers and conductive small molecules.
It is called 'organic' electronics because the polymers and small molecules are carbon-based.
History of Organic Electronic
1950’s: Work on crystalline organics materials starts.
(At that time organic crystal where considered to be an alternative to silicon)
1970’s: Organic photoconductors (xerography)
1980’s: Organic non-linear optical materials
1987: Kodak group published the first efficient organic light emitting device(OLED)
Results on the first organic transistor where published.
1990’s: Friend group (Cambridge University) published the first results on polymer light emitting diodes.
2000: Noble price in chemistry for the “discovering and development of conductive polymers” (Heeger, MacDiarmid and Shirakawa)
2000’s: Organic solar cells with efficiencies of >5% were realized.
