Organic vs. Inorganic
Why Organic Electronics?
Flexible
Lighter
Low cost
Biodegradable
This opens the door to many exciting and advanced new applications that would be impossible using copper or silicon.
Why Organic?

Why not Organic?
Disadvantages
High Resistance
Smaller bandwidths
Shorter lifetimes
Dependant on stable environment
Applications
Displays:
• (OLED) Organic Light Emitting Diodes
RFID :
• Organic Nano-Radio Frequency Identification Devices
• Solar cells
Organic Light Emitting Diodes (OLEDs)
An OLED is a thin film LED in which the emissive layer is an organic compound.
When this layer is polymeric (or plastic), OLEDs can be deposited in rows and columns on a screen using simple printing methods that are much more efficient than those used in manufacturing traditional LEDs.
A key benefit of OLEDs is that they don’t need a backlight to function.
How it Works
An electron and hole pair is generated inside the emissive layer by a cathode and a transparent anode, respectively.
When the electron and hole combine, a photon is produced, which will show up as a
dot of light on the screen.
Many OLEDs together on a screen make up a picture
Less expensive to produce
Wide range of colors and viewing angle
Consumes much less energy than traditional LCDs.
Flexible and extremely thin
Limited lifetime of about 1,000 hours.
Susceptible to water

Production and Applications
Quicker Checkout
Reduced Waste
Efficient flow of goods from manufacturer to consumer
Solar Cells
The light falls on the polymer
Electron/hole is generated
The electron is captured C60
The electricity is passed by the nanotube
The Future of Organic Electronics
• Integrates electronic devices into textiles, like clothing
.Made possible because of low fabrication temperatures
->Smart Textiles
->Lab on a Chip
• A device that incorporates multiple laboratory functions in a single chip
• Organic is replacing some Si fabrication methods:
-Lower cost
-Easier to manufacture
-More flexible
->Portable, Compact Screens
• Screens that can roll up into small devices
• Black and White prototype already made by Philips
(Shown at the bottom-left)
• Color devices will be here eventually
