Solar Panel Battery — The Basics
A solar panel battery is made up of individual solar (photovoltaic) cells that convert solar radiation into electrical energy. This is known as the photovoltaic effect.
A solar panel battery is different from a normal battery. A normal battery converts chemical energy into electrical energy while a solar panel converts sunlight into electrical energy. While a normal battery has the capacity to store energy, a solar panel depends on external resources to do that.
A semiconductor is the medium through which electron movement takes place. As photons hits the surface of the material, electrons are displaced, creating a potential difference. This phenomenon was accidentally discovered when scientists observed that silicon doped with some impurities became very sensitive to light. Very soon, mankind began researching into various materials to make photovoltaic cells.
