Definition of photovoltaic cell in science terms

What is a photovoltaic cell?

A photovoltaic cell is the most critical part of a solar panel that allows it to convert sunlight into electricity. The two main types of solar cells are monocrystalline and polycrystalline. The "photovoltaic effect" refers to the conversion of solar energy to electrical energy.

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.

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 effect?

A diagram showing the photovoltaic effect. The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. These solar cells are composed of two different types of semiconductors —a p-type and an n-type—that are joined together to create a p-n junction.

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.

Why are photovoltaic cells important?

In remote locations, photovoltaic systems are indispensable, offering reliable energy for telecommunications, water pumping, and medical refrigeration in off-grid areas. Furthermore, the cells are pivotal in space exploration, serving as the primary energy source for satellites and space probes.
