Question

what is photovoltaic technology​

Answer 1

Answer:

Photovoltaic (PV) materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power

Answer 2

Explanation:

Hey Friend,

A photovoltaic is also simply called a solar cell.

• There are various devices for energy conversions. Similarly, a solar cell / photovoltaic cell is an electrical device which is used to convert light energy into electric energy!.

• It is widely used in solar pannels, wrist watches etc.

• It traps the sun's energy (photons) and causes a flow of electrons, thereby converting the light energy to electric energy...

   working of photovoltaic technology

• 1. When light is allowed to incident on a P-N junction diode, photons collide with valence electrons and impart them sufficient energy enabling them to leave their parent atoms.

• 2. Thus, electron - hole pairs are generated in both the P and the N-sides of the junction.

• 3. These electrons and holes reach the deflection region by diffusion and are then separated by the strong barrier field existing there.

• 4. However, the minority carries, electrons in the P-side slide down the barrier to reach the N-side and the holes in the N-side move to P-side.

• 5. Their flow constitutes the minority current which is directly proportional to the illumination and also depends on the surface area being exposed to light.
