The first is the one you''re likely most familiar with – photovoltaics, or PV. These are the panels you''ve seen on rooftops or in fields. When the sun shines onto a solar panel, photons from the sunlight are absorbed by the cells in the panel, which creates an electric field across the layers and causes electricity to flow.
When these photons make contact with a PV cell, they transfer their energy to the electrons in the atoms of the cell''s material. These energized electrons break free from their atoms, creating an electric current. This process, known as the photovoltaic effect, is the basis of how solar energy is converted into electricity using PV systems.
Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells.
