How does a photovoltaic panel work?
A photovoltaic cell is a semiconductor. When light hits the photovoltaic (or PV) cell, the light can be reflected or absorbed or it can pass through the cell. If the light is absorbed into the cell, the light’s energy is transferred to the electrons in the semiconductor. This causes the electrons to flow, creating an electrical current. Both PV cells and LEDs are semiconductors We can learn how PV cells work by experimenting with light emitting diodes (LEDs), because both are semiconductors.
