6 FAQs about [Solar cell photovoltaic conversion]

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.

How do solar cells convert sunlight into electricity?

Solar cells, also called photovoltaic cells, convert sunlight directly into electricity. Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.

How do photovoltaic cells work?

Simply put, photovoltaic cells allow solar panels to convert sunlight into electricity. You've probably seen solar panels on rooftops all around your neighborhood, but do you know how they work to generate electricity?

What is the photovoltaic process?

The photovoltaic process bears certain similarities to photosynthesis, the process by which the energy in light is converted into chemical energy in plants. Since solar cells obviously cannot produce electric power in the dark, part of the energy they develop under light is stored, in many applications, for use when light is not available.

Can a photovoltaic cell produce enough electricity?

A photovoltaic cell alone cannot produce enough usable electricity for more than a small electronic gadget. Solar cells are wired together and installed on top of a substrate like metal or glass to create solar panels, which are installed in groups to form a solar power system to produce the energy for a home.
