Solar Cell
1. What is the lifespan of Solar Cell?
The lifespan of an Solar Cell generally has 25-30 years, and these come along with warranties based on their performance from the manufacturer.
2. What type of material is used in making solar cells?
Type of material which is used in making solar cells is Crystalline silicon. This Crystalline silicon cells is made by connecting silicon atoms one to one another to form a crystal lattice. This crystal lattice makes efficient conversion of electric current.
3. Why do we need to use Solar Cell?
We need to use Solar Cell because ,Solar cells last for longer time and it has no maintenance cost. Solar Cells provide sustainable environment because no pollution is associated by using solar panels.
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.
