Solar Cell- An Overview
Solar Energy is the conversation of sunlight into electricity. it is renewable energy source, available every day in day light.
A Solar Cell is also called photovoltaic cell, it is an electrical device that converts energy of sunlight directly into electricity by the photovoltaic effect. The first solar cell was invented by Charles Fritts within the 1880s. A single solar cell generate only 0.5 ~0.6 Volt, so in solar panel manufacturing solar cell connected in series to produce required output voltage.
Solar Cell
Type of Solar panel
1. Monocrystalline solar panel
2. Polycrystalline solar panel
Monocrystalline solar panel made of single crystal of pure silicon .
Polycrystalline solar panel made of multi crystal of pure silicon .
Advantage of Solar Panel
- Solar energy pollute far less compared to other source of energy generation.
- Maintenance free.
- Need less people to handle solar plant compare to other source of energy.
- High initial cost .
- Required more space on large scale production.
- Energy generation depends on weather condition, in monsoon solar panel generate less energy then summer.
