Organic electronics is a branch of electronics that deals with conductive polymers, plastics, or small molecules.Polymer electronics are laminar electronics, that also includes transparent electronic package and paper based electronics It is called 'organic' electronics because the polymers and small molecules are carbon-based, like the molecules of living things. This is as opposed to traditional electronics (or metal electronics) which relies on inorganic conductors such as copper or silicon.In addition to organic Charge transfer complexes, technically, electrically conductive polymers are mainly derivatives of polyacetylene black (the "simplest melanin").Conductive polymers are lighter, more flexible, and less expensive than inorganic conductors. This makes them a desirable alternative in many applications. It also creates the possibility of new applications that would be impossible using copper or silicon

Organic Electronics
Organic electronics, or plastic electronics, is the branch of electronics that deals with conductive polymers, which are carbon based.
Inorganic electronics, on the other hand, relies on inorganic conductors like copper or silicon.
Why Organic?
Advantages
Organic electronics are lighter, more flexible
Low-Cost Electronics
No vacuum processing
No lithography (printing)
Low-cost substrates (plastic, paper, even cloth…)
Direct integration on package (lower insertion costs)
Why Organic?

How do molecules act as semiconductors?
We have:
• bound electrons between the atoms in the ring (sp2)
• A cloud of partly free electrons above and below the ring (p-electrons)
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
Organic transistors
• INTRODUCTION
Organic transistors are transistors that use organic molecules rather than silicon for their active material. This active material can be composed of a wide variety of molecules.
• Advantages of organic transistors:
– Compatibility with plastic substances
– Lower temperature is used while manufacturing (60-120°C)
– Lower cost and deposition processes such as spin-coating, printing and evaporation
– Less need to worry about dangling bonds( simplifies the process)
• Disadvantages of organic transistors:
– Lower mobility and switching speeds compared to Si wafers
– Usually does not operate under invasion mode.

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
