What is a Solar cell?
It is a device that directly converts solar energy to electrical energy. A typical solar cell consists of a 2 cm2 piece of pure silicon. It can produce about 0.7 watts of electricity when exposed to sunlight. A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms such as boron or gallium that have one less electron in their outer energy level than does silicon.
Uses of Solar cell
- Solar cells are used to convert light source from the sun into electrical energy.
- Solar cells are used in power farms to provide electricity to large areas.
- It is eco-friendly
- Solar cells are very useful in powering space vehicles such as satellites
