Why Is Silicon Used To Make Solar Panels

These photovoltaic cells are made using silicon.

Why is silicon used to make solar panels.

Amorphous silicon cells are non crystalline and instead are attached to a substrate like glass plastic or metal. The basic component of a solar cell is pure silicon which has been used as an electrical component for decades. Need the blue gem to make the solar panels. The first two shells which hold two and eight electrons.

You have to burn a lot of hardwood trees to make charcoal for smelting solar silicon because about 75 of the wood is lost to smoke heat and co2. These panels can also become a source of free electricity if they charge a rechargeable battery which can then be used to supply power to the homes. The silicon used to make monocrystalline solar cells has a high level of purity. The working of a solar energy system is dependent on the efficiency of the photovoltaic cells.

Solar panels are made up of solar photo voltaic pv cells. Bandgap http photochemistry epfl ch pc pc2 lesson 6 pdf the same electrical property of silicon that makes it conductive in one direction and insulating in the. Currently over 90 of the current solar cell market is based on silicon. For this reason thin film solar panels are true to their name.

Finally amorphous silicon cells create flexible solar panel materials that are often used in thin film solar panels. It s an semiconductor material. In households silicon solar panels placed on rooftops can serve as a stand alone system used to heat water for home consumption. They are lean and bendable unlike a standard panel.

Silicon has some special chemical properties especially in its crystalline form. An atom of sili con has 14 electrons arranged in three different shells. To understand how silicon solar panels make electricity requires shrinking down to the atomic level. Silicon has an atomic number of 14 which means that it has 14 protons in its center and 14.

Silicon is a semiconductor. Silicon solar panels are often referred to as 1 st generation panels as the silicon solar cell technology gained ground already in the 1950s. The silicon is all oriented the same way in a monocrystalline solar cell creating one large silicon crystal.
