Solar cells make
electricity directly from sunlight. It's the most trusted vitality technology ever made,
which is why it's used on satellites in house
and in remote places on Earth where it is hard to fix problems.

How do photo voltaic cells work? Solar cells are made using
silicon atoms. An atom is principally a building block - identical to a Lego brick
but so tiny you’d want a particular machine to see them.
Because the silicon atoms are so small you want trillions and trillions of them for
a solar cell. To make the solar cell you want a wafer layer of silicon, about the identical dimension as a dinner plate however a
lot a lot thinner - solely about 3 times the thickness of a
strand of your hair. This silicon layer is changed in a particular method
using sizzling temperatures of as much as 1,000℃.
Then, a sheet of metallic is put onto the back of the layer and a metal mesh with holes in it, like a
internet, is placed on the entrance.If the sunlight is vivid, then plenty of electrons get hit and so a lot of electric current can flow. Whether it is cloudy, then fewer electrons get hit and the current shall be lower by three quarters or extra. At night, the solar panel produces no electric power and we need to depend on batteries or other sources of electricity to maintain the lights on. How are photo voltaic cells being used? Solar cells are the most cost effective option to make electricity - cheaper than new coal or nuclear power stations. That is why photo voltaic cells are being installed all over the world about 5 instances sooner than coal power stations and 20 instances faster than nuclear energy stations. In Australia, practically all new power stations are both solar power stations or wind farms. Solar and wind electricity can be used to run electric automobiles instead of polluting petrol cars. Solar and wind electricity can also heat and cool your house and might be used in business rather than coal and pure gas. Solar and wind are serving to lessen the amount of greenhouse gases which injury our Earth. They are cheap, they usually proceed to get even cheaper and the extra we use it the faster we can stop using power that can damage the Earth (like coal, oil and fuel). What’s more, silicon is the second commonest atom in the world (after oxygen). In actual fact, sand and rocks are product of largely silicon and oxygen. So, we might by no means run out of silicon to make extra solar cells. Read extra: Curious Kids: why do we not use the magnetic energy the Earth offers to create electricity? Hello, curious youngsters! Have you got a query you’d like an professional to reply?
Curious Kids: how do solar panels work? Australian National University supplies funding as a member of The Conversation AU. The Conversation is funded by the National Research Foundation, eight universities, including the Cape Peninsula University of Technology, Rhodes University, Stellenbosch University and the universities of Cape Town, Johannesburg, Kwa-Zulu Natal, Pretoria, and South Africa. It's hosted by the universities of the Witwatersrand and Western Cape, the African Population and Health Research Centre and the Nigerian Academy of Science. The Bill & Melinda Gates Foundation is a Strategic Partner. How do solar panels work? Nathan, age 5, Melbourne, Australia. The Sun produces a lot of vitality known as photo voltaic energy. Australia gets 20,000 times more power from the Sun each day than we do from oil, gas and coal. This solar vitality will continue for as long because the Sun lives, which is another 5 billion years. Solar panels are made from photo voltaic cells, which is the part that turns the solar energy in sunlight into electricity.
It is this mesh side of the layer that will face the Sun. When 60 solar cells are made they are fastened collectively behind a layer of glass to make a photo voltaic panel. If your own home has a solar energy system, it should probably have 10 to 50 solar panels connected to your roof. Millions of solar panels are used to make a big photo voltaic farm out within the countryside. Each silicon atom incorporates extremely tiny and lightweight things referred to as electrons. These electrons every carry a small electric cost. When sunlight falls on a photo voltaic panel it will possibly hit one of many electrons in a silicon atom and knock it free. These electrons can transfer around however because of the special method the cell is made they'll only go a method, up towards the side that faces the Sun. They can’t go the opposite manner. So whenever the Sun is shining on the solar cell it causes many electrons to stream upwards however not downwards, and this creates the electric current needed to energy issues in our houses corresponding to lights, the tv and other electrical items.
