Photovoltaic Cell is an electronic device that captures solar energy and transforms it into electrical energy. It is made up of a semiconductor layer that has been carefully processed to transform sun energy into electrical energy. The term "photovoltaic" originates from the combination of two words: "photo," which comes from the Greek word "phos," meaning
Electron Hole Formation. As we know that photon is a flux of light particles and photovoltaic energy conversion relies on the number of photons striking the earth. On a clear day, about 4.4 x 10 17 photons strike a square centimeter of the Earth''s surface every second. Only some of these photons that are having energy in excess of the band gap are convertible to

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.
When sunlight hits layers of silicon inside solar cells, an electric charge builds up, creating a flow of electricity. Solar panels are mainly located on the roofs of homes and buildings and can generate electricity and heat water free of charge. In the Northern Hemisphere (including Scotland) solar panels work best when they face south.
Solar cells convert light from the sun directly into electricity. Sunlight is made up of tiny packets of energy called photons. When sunlight hits a solar cell, the photons knock free minute particles called electrons contained inside. As the electrons begin to move about they are 'routed' into a current.
The gas is distilled to remove the impurities, it then enters a reactor and slowly collects on the surface of rods forming pure silicon. The pure silicon rods are broken up, melted and cooled to form ingot blocks. As the material cools, the atoms join and form crystals. The blocks are then cut up into thin sheets and used as solar cells.
Solar panels are used to produce electricity. They can be found on buildings but can also be used on a solar farm to harvest the power of the sun. Solar panels are made from lots of solar cells. solar cell Solar cells are put together to make a solar panel.
