How Does Solar Energy Work?
● Solar cells are made of semiconductors such as silicon, a special material that can absorb light as energy.
● When absorbing light, the energy knocks electrons loose.
● These electrons are collected and flow along conductors in the PV cell.
● This flow of electrons, called a current, can be used as an immediate power source or stored in batteries for later use.
● The current combined with the cell’s voltage determines the amount of power the PV cell can produce.
