About Organic Nano generator:

The device can generate current and voltage from minute amounts of heat or light that fall on it.
The experimental exploration of energy materials has led to the successful synthesis of an organic energy material called polyaniline-rubrene, and they have fabricated an Organic Pyroelectric Nanogenerator (OPyNG).
The pyroelectric effect of the device is induced by the light-induced change in spontaneous polarization occurring in the ultra-thin oxidized surface layer of the polyaniline-rubrene thin film.
What is pyroelectric effect?
- The pyroelectric effect is the change in polarization due to the change in temperature.
- Ferroelectric materials are expected to be strongly pyroelectric because ferroelectric materials have a large range of temperature-dependent spontaneous polarization
This effect holds a unique advantage in the pyroelectric nanogenerator (PyNG), as it can optically induce the pyroelectric effect, which is useful for energy harvesting.
The fabricated OPyNG device utilizing organic material provides new insights and opens up new avenues for harvesting energy from organic materials.
The OPyNG operates in the UV-visible-NIR region in self-powered mode, and it offers significant advantages as it can function as a self-sustainable standalone device.

Q1) What is Polyaniline?

Polyaniline is a versatile and widely studied conducting polymer. It is formed through the polymerization of aniline monomers, which are aromatic amines.
