What is solar cell Class 12?

(a) A solar cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect that is exhibited by semiconductors. … The top layer is doped the opposite way, that is it has slightly more electrons which are also known as the n-type semiconductor silicon.

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 is a solar cell in biology?

A solar cell (or a “photovoltaic” cell) is a device that converts photons from the sun (solar light) into electricity. In general, a solar cell that includes both solar and nonsolar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell.

What are solar cells how do they 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 a solar cell also known as?

When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the “semi” means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal.

IT\'S FUNNING:  How does the earth produce energy?

What is solar cell Class 10?

Solar cell is a device which converts solar energy (or sun’s energy directly into electricity. A solar cell converts sunlight energy into electrical energy. A solar cell is usually made from silicon. … This group of solar cells is called a solar cell panel.

What is solar cell class6?

Answer: A cell which directly converts the light coming from the sun into electrical energy is known as a solar cell.

What is solar cell and how it works?

A solar cell is made up of two layers of silicon that are treated to let electricity flow through them when exposed to sunlight. One layer is positively charged, the other negatively charged. As photons enter the layers, they give up their energy to the atoms in the silicon in the form of electrons.

What is solar cell PDF?

A solar cell is an electronic device which directly converts sunlight into electricity. Light shining on the solar cell produces both a current and a voltage to generate electric power. … The electron then dissipates its energy in the external circuit and returns to the solar cell.

What is solar cell principle?

Solar cells or photovoltaic cells are made based on the principle of the photovoltaic effect. They convert sunlight into direct current (DC) electricity. … Light striking the crystals induces the “photovoltaic effect,” which generates electricity.
