Silicon solar cells, one of the most popular and effective photovoltaic (PV) technologies, have completely changed the solar energy market. The various varieties of silicon solar cells, their applications, and their benefits and drawbacks are all covered in this page. How Do Silicon Solar Cells Work?
Two different forms of silicon, pure silicon and amorphous silicon are used to build the cells. However, the use of the photovoltaic cells has been limited due to high processing cost of high purity single crystal material used and the lack of effective mass production techniques used to produce thin silicon films.
Silicon solar cells have gained immense popularity over time, and the reasons are many. Like all solar cells, a silicon solar cell also has many benefits: It has an energy efficiency of more than 20%. It is a non-toxic material. Therefore, it is not harmful to the environment.
A silicon solar cell works the same way as other types of solar cells. When the sun rays fall on the silicon solar cells within the solar panels, they take the photons from the sunlight during the daylight hours and convert them into free electrons. The electrons pass through the electric wires and supply electric energy to the power grid.
One more characteristic that really influence the decision of using silicon over any other kinds of materials mentioned above is its non-hazardous properties. As silicon is a non-toxic material, it has very low effect on the environment. These all characteristic of silicon makes it worth to be used in the photovoltaic cell.
Silica is utilized to create metallurgical grade silicon (MG-Si), which is subsequently refined and purified through a number of phases to create high-purity silicon which can be utilized in the solar cells. The silicon is first extracted from beach sand. Sand mining is only carried out on a few numbers of beaches throughout the globe.
