Solar Energy- Photovoltaic cellsHow do they work?▫Photovoltaic cells should convert sunlight to

electricity.▫For that we need

Sunlight Some material that can generate electrons

when light is incident on it.

Silicon is used for its properties to generate electrons easily!

All electronics also use Silicon.

Solar cell

Has two electrodes, positive and a negative(similar to a battery) The energy of the sunlight(photon) removes electrons from Silicon and cause electricity.
