Photovoltaic Cell Explanation Video Tutorial

How does a photovoltaic cell work?

The working principle of a photovoltaic (PV) cell involves the conversion of sunlight into electricity through the photovoltaic effect. Here's how it works: Absorption of Sunlight: When sunlight (which consists of photons) strikes the surface of the PV cell, it penetrates into the semiconductor material (usually silicon) of the cell.

What is the working principle of a photovoltaic cell?

Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.

What is a photovoltaic cell?

A photovoltaic cell is a specific type of PN junction diode that is intended to convert light energy into electrical power. These cells usually operate in a reverse bias environment. Photovoltaic cells and solar cells have different features, yet they work on similar principles.

How are solar panels made?

Solar panels are made from lots of solar cells. solar cell Solar cells are put together to make a solar panel. Made from a material called silicon, solar cells convert the light from the sun into electricity. You can see an example of solar cells on the top of some calculators.

What do solar cells do?

This is a simple explanation of what solar cells do and how they may be used to provide energy in the future. This short animated video from TVNZ demystifies some of the technical language. What are solar cells? Solar cells convert light from the sun directly into electricity. Sunlight is made up of tiny packets of energy called photons.

How does a PV cell work?

Separation of Charges: Due to the built-in electric field within the PV cell (created by the junction between different semiconductor layers), the newly generated electron-hole pairs are separated. Electrons are pushed towards the n-type (negative) side of the cell, while holes are pushed towards the p-type (positive) side.
