Question

What is organic semiconductor ? Explain with an example.

Answer 1

Organic semiconductor:

1. Organic semiconductors are solids composed of pi-bonded molecules or polymers composed of hydrocarbons and heteroatoms such as nitrogen, sulphur, and oxygen.
2. They can be found as molecular crystals or as amorphous thin films.
3. In general, they are insulators that become semiconducting when charges are injected through appropriate electrodes, doped, or photoexcited.
4. Organic semiconductors include organic light-emitting diodes (OLEDs), organic solar cells (OSCs), and organic field-effect transistors (OFETs).
