2. Organic Electronics Also named: plastic/polymer electronics “Organic” = carbon-based Traditional conductor: copper or silicon Benefits: lighter, more flexible, and less expensive Application markets: OLED Displays, OLED Lighting, RFID Tags, OTFT Backplanes, TFPV/Organic Photovoltaic, and Sensors

3. History 1977, discovery and development of highly- conductive polymers “polyacetylene” 2000, Nobel Prize in Chemistry Alan J. Heeger Alan G. MacDiarmid Hideki Shirakawa 1990s, plastic electronics on thin and flexible plastic substrates was developed – Cambridge University’s Cavendish Laboratory

4. Features Categories Semiconductors Dielectrics Conductors Light emitters Applications Printed Electronics Smart windows Electronic paper Solar cell

5. Printed Electronics A set of printing methods used to create electrically functional devices “Functional inks” carbon-based compounds Material: plastic, ceramic, silicon Organic/Inorganic/Hybrid Low-cost, low-performance electronics: flexible displays smart labels decorative and animated posters active clothing.

7. Smart Glass Application: windows or skylights Control the amount of light and heat passing through with the press of a button Electrically switchable technologies: Electro-chromic devices Suspended particle devices Polymer dispersed liquid crystal devices Benefits: Save cost for lighting, heating, air-conditioning Block UV rays Provide privacy

8. Smart Glass

9. Electronic Paper Mimic ordinary ink on paper No back-light, reflects light Holding text/images indefinitely without drawing electricity Allowing image to be changed later Light, flexible, durable, non-fading Comfortable to read, can be read in direct sunlight

10. Organic Solar Cell Also named: plastic solar cell, organic photovoltaic cell (OPVC) Inexpensive organic polymers instead of expensive crystalline silicon Light absorption and charge transport High absorption coefficient Low efficiency, low stability and low strength Types of POVC: Single layer Multi-layer Dispersed hetero-junction
