The main component of silicon solar cells is silicon, and it has been used as the primary component for decades. Pure silicon is a bad conductor of electricity; therefore, to overcome this problem, the silicon used in solar cells has some impurities. This is achieved by adding some other atoms into the silicon atoms to improve silicon’s ability to capture the sun’s energy easily and help in converting the solar energy into electricity.
Silicon Solar Cell Structure
In the structure of silicon atoms, a gallium atom is placed since it has one less electron compared to a gallium structure. Similarly, when an arsenic atom is placed in between lots of silicon solar cells, adding an extra electron creates an electron-rich layer. When gallium atoms are used, there will be a lack of electrons, which results in an electron-poor layer formation. In the solar cells, the layers are placed close to each other, which results in the creation of an electric field. When the sun rays fall on the cells, the electrons leave the holes behind. Since there is an electric field, they migrate to the electrodes in the cell, and there is the formation of electricity.
Silicon Solar Cell – Usage Details To Learn
Earlier, when we understood silicon’s importance in manufacturing silicon solar cells, we also required solar panels made from silicon used to be very expensive and very high-quality silicon for creating them. Before the interfering of gallium with silicon was done, silicon’s purification procedure was a very time-consuming and costly method. After developing technology, cheaper and low-quality silicon was used, making the silicon more affordable with some help from the government.
Types Of Silicon Solar Cells
Following are the types of silicon solar cells: –
Monocrystalline solar cell: – it is made from the purest type of silicon, making it the most efficient type of material used in solar cells. Monocrystalline solar cells are dark blue.
Polycrystalline solar cells: – the silicon used is melted and poured onto a square shape. Since it doesn’t undergo any cutting process, hardly any silicon is wasted during the manufacturing process. It is also more affordable.
Amorphous solar cells: – these cells are used for smaller purposes such as pocket calculators, among others.
Limitations Of Silicon Solar Cells
There could be certain limitations even if it is a Silicon Solar cell and we have discussed the theme in the following. Since the silicon panels are fragile and rigid, they cannot be transported from one place to another. Compared to the alternate options, these cells are still expensive.
Since almost 90% of all solar appliances use silicon solar cells to generate electricity, it is widely used in many industries and commercial uses. You have to learn more about solar energy and all the efficiency it can provide to your surroundings before it comes to the practice in common. People have started relying upon the Solar source and there is no going back once a find how efficiently they can use it and it starts by learning about simple appliances like Silicon solar cells and how it could generate electricity.
