Electricity Generation using Solar Energy - Solar Photovoltaic Cell

Solar photovoltaic cell converts the solar radiation energy directly into electrical energy. This is called solar photovoltaic effect.

1. Working Principle:
   Solar photovoltaic cells convert solar radiation energy directly into electrical energy through the solar photovoltaic effect.
2. Electricity Output:
   A single silicon solar cell produces DC electrical power, and multiple cells can be connected in series and/or parallel to increase voltage and current.
3. Energy Transformation:
   Energy in sunlight → Photovoltaic effect → DC electrical power.
4. Utility Conversion:
   Since most appliances use AC power, DC electricity from solar cells is converted to AC using an inverter before feeding into the grid or loads.
5. Environmental Benefit:
   Solar PV generation produces no air pollution and generates electricity without burning any fuel, though it works only when sunlight is available.
