What Is The Basic Principle Of Solar Cell?

A solar cell is a device that directly converts the energy of light into electrical energy through

the photovoltaic effect

. Solar cells or photovoltaic cells are made based on the principle of the photovoltaic effect. They convert sunlight into direct current (DC) electricity.

What is the basic structure of solar cell?

A solar cell consists of

a layer of p-type silicon placed next to a layer of n-type silicon

(Fig. 1). In the n-type layer, there is an excess of electrons, and in the p-type layer, there is an excess of positively charged holes (which are vacancies due to the lack of valence electrons).

What is the principle of solar cell Class 12?

A solar cell which is also known as a photovoltaic cell or PV cell is defined as an electrical device which converts the light energy to electrical energy through

the photovoltaic effect

(principle of working of solar cell). A solar cell can be treated as a p-n junction diode.

What is working principle of solar cell and mention its one use?

Solar cell is also known as a Photovoltaic cell or PV cell. From the name itself we can understand that it works on the principle of

photovoltaic effect

. Photovoltaic effect can be defined as a process which generates voltage or electric current in a photovoltaic cell or a solar cell when it is exposed to sunlight.

Which material is used in solar cells?

Silicon

.

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 advantages of solar cells?

Renewable energy – The energy can be used both to generate electricity and heat in the house, either through solar PV or solar thermal. Renewable energy is recovered from the sun, the wind and waves – which in this case is the sun. Solar cells

harness the energy from the sun and transform this into usable electricity

.

What is the function of solar cell?

A solar cell

transforms sunlight directly into electrical energy

., A solar cell or photovoltaic cell is a wide area electronic device that converts solar energy into electricity by the photovoltaic effect.

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 difference between photodiode and solar cell?

A photo diode is made to detect light quickly whereas

a solar cell is made to collect energy from light

. They are both typically silicon diodes, but modified to meet their different requirements. A photo diode has to be fast, which means low capacitance, which means small area of silicon.

How pn junction works in solar cell?

A solar cell is essential a PN junction with a large surface area. The N-type material is kept thin to allow light to pass through to the PN junction. … When

a photon of light is absorbed by one of these atoms in the

N-Type silicon it will dislodge an electron, creating a free electron and a hole.

What are the types of solar cells?

• Crystalline silicon cells.
• Monocrystalline cells.
• Polycrystalline cells.
• Thin film solar cells.

What is a solar cell class 8?

3,192 views • Dec 13, 2015 • A

photoelectric cell designed to convert sunlight into electrical energy

, typically consisting of layers or sheets of specially prepared silicon.

Which material has highest solar cell efficiency?

Copper indium gallium selenide (CIGS)

is a direct band gap material. It has the highest efficiency (~20%) among all commercially significant thin film materials (see CIGS solar cell).

Why silicon is used in solar cell?

Silicon is one of the optimum semiconductors that is used for solar cell production because of

its superior electronic properties, optical properties, thermal properties and mechanical as well as environmental properties

. In addition to its availability, manufactureability, and cost.

What are the advantages and disadvantages of solar cell?

What are 5 advantages of solar energy?

• Solar power reduces your monthly bills.
• Solar panels increase your property value.
• Solar panels clean up our air.
• Solar power keeps you connected and in control.
• Solar panels help keep your home powered during blackouts.
