Silicon is a widely used material in the production of solar cells. Solar cells are devices that convert sunlight into electricity. The use of silicon in solar cells is due to its unique properties, which make it an ideal material for solar panel production. Solar power is one of the fastest-growing sources of renewable energy, and the UK has set a target to generate 40% of its electricity from renewable sources by 2030. In this article, we will discuss why silicon is used in solar cells.
Silicon is a semiconductor material that has a unique property of being able to absorb light energy and convert it into electricity. This property makes it an ideal material for solar panel production. Silicon has four valence electrons, which means it can bond with four other atoms. When silicon is exposed to sunlight, it releases some of its electrons, which are then collected by the solar cell. This process creates an electric current, which can be used to power homes and businesses.
The use of silicon in solar panels is due to its abundance and availability. Silicon is the second most abundant element in the Earth’s crust, making up about 28% of its mass. This means that silicon is readily available and can be easily extracted from the Earth. The UK has a growing solar industry, and the availability of silicon has made it easier and cheaper for companies to produce solar panels.
Another reason why silicon is used in solar panels is its efficiency. Silicon solar panels can convert up to 20% of the sunlight that hits them into electricity. This means that silicon solar panels are highly efficient and can produce a significant amount of electricity. The efficiency of silicon solar panels has improved over the years, and researchers are continually finding new ways to improve their efficiency.
Silicon is also a durable material, which makes it ideal for use in solar panels. Silicon solar panels can last for up to 25 years, and they require little maintenance. The durability of silicon solar panels has made them a popular choice for homeowners and businesses that want to invest in renewable energy.
Silicon solar panels are also environmentally friendly. They do not emit any greenhouse gases or pollutants, making them a clean source of energy. The production of silicon solar panels requires less energy than other types of solar panels, making them more sustainable.
In conclusion, silicon is used in solar cells because of its unique properties, abundance, availability, efficiency, durability, and environmental friendliness. The use of silicon in solar panels has made it easier and cheaper for companies to produce solar panels, and it has made solar power more accessible to homeowners and businesses. The UK has set a target to generate 40% of its electricity from renewable sources by 2030, and the use of silicon in solar panels will play a significant role in achieving this goal.
