What is solar cell explain its working?

A solar cell is a sandwich of n-type silicon (blue) and p-type silicon (red). … It generates electricity by using sunlight to make electrons hop across the junction between the different flavors of silicon: When sunlight shines on the cell, photons (light particles) bombard the upper surface.

What is solar cell its working class 12?

Solar cell

Principle–These photo voltaic devices convert the optical radiation into electricity. Circuit. When solar light falls on a p-n junction, it generates emf. As the solar radiation is incident at the junction, the junction area is kept much larger for more power generation.

What is a solar cell explain?

A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. … Individual solar cell devices can be combined to form modules, otherwise known as solar panels.

What is a solar cell and how does it work class 12?

Hint: A solar cell is a device which converts light energy into electrical energy. It is a semiconductor device which allows conduction of current when light is shown on it, due to its p-n junction. Complete step by step answer: A solar cell can also be known as a photovoltaic cell.

What is the symbol of solar cell?

The symbol is shown below. As shown in the given diagram the Solar cell is like an ordinary diode. It consist of silicon, germanium PN junction with a glass windows on the top surface layer of P-Type, the P-Type material is made very thin and wide so that the incident light photon may easily reach to PN junction.

What is solar cell short answer?

Solar cell, also called photovoltaic cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect.

What are the advantages of solar cell?

Benefits or Advantages of Solar Cell

It is very easy to operate compare to other power sources of re-newable type. ➨It does not produce any noise as it does not have any moving parts. ➨It does not generate emissions or radiations. ➨It does not require fuels or water to produce electricity.

Which is used in solar cell?

Silicon is, by far, the most common semiconductor material used in solar cells, representing approximately 95% of the modules sold today. It is also the second most abundant material on Earth (after oxygen) and the most common semiconductor used in computer chips.

What are solar cells how do they work explain with a neat diagram?

1) Solar cell works under the principle of photovoltaic effect-when light is incident on ‘P-N’ junction a potential gets developed across the junction, this potential is capable of driving a current through the circuit. 2) Hence light energy is getting converted to electrical energy.

What is another name for solar cells?

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.

What are solar cells diagram?

A solar cell is basically a p-n junction diode. Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics – such as current, voltage, or resistance – vary when exposed to light. Individual solar cells can be combined to form modules commonly known as solar panels.

How can I make a solar cell?

To make solar cells, the raw materials—silicon dioxide of either quartzite gravel or crushed quartz—are first placed into an electric arc furnace, where a carbon arc is applied to release the oxygen. The products are carbon dioxide and molten silicon.

What are the characteristics of solar cells?

The basic characteristics of a solar cell are the short-circuit current (ISC), the open-circuit voltage (VOC), the fill factor (FF) and the solar energy conversion efficiency (η).
