Primary Key Terminologies of Solar Cell
- Solar Cel : It is a device which converts sunlight energy into electrical energy using photovoltaic effect.
- Photovoltaic Effect: It is a phenomenon when some materials are exposed to light then it generates electric current.
- Solar Panel : Solar Panel is a collection of solar cells which are connected to produce a higher level electrical output.
- Solar Array: Solar Array is a system where it contains multiple solar panels ,which is designed to generate a large amount of electricity.
Solar Cell
A Solar Cell is a device that converts light energy into electrical energy using the photovoltaic effect. A solar cell is also known as a photovoltaic cell(PV cell). A solar cell is made up of two types of semiconductors, one is called the p-type silicon layer and the n-type silicon layer. So Solar cell is a p-n junction diode.
The solar energy from the sun in the form of photons creates loose electrons on the n-type semiconductor and holes on the p-type semiconductor. These loose electrons are collected on the aluminum layer and start flowing thus resulting in an electric current.
