How do solar photovoltaics work?
Solar photovoltaics work by directly converting sunlight into electricity through the photovoltaic effect. This process occurs in photovoltaic cells, usually made of silicon, a semiconductor material. When sunlight hits these cells, the photons transfer their energy to the electrons in the material, generating a direct electric current.
How do solar photovoltaic cells convert sunlight to electricity?
Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. The efficiency that PV cells convert sunlight to electricity varies by the type of semiconductor material and PV cell technology.
How do solar panels generate electricity?
Solar panels generate electricity by absorbing sunlight with solar cells. They use this sunlight to create direct current (DC) electricity through a process called 'the photovoltaic effect'.
What is a photovoltaic (PV) cell?
A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.
