The inorganic solar cell relies on chemistry, chemical principles, and the effects of chemical reactions to efficiently convert sunlight into electricity through a semiconducting p-n junction.
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 photovoltaic cells work?
Photovoltaic cells may operate under sunlight or artificial light. In addition to producing energy, they can be used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity. The operation of a PV cell requires three basic attributes:
What is the difference between solar thermal and photovoltaic?
They both use the same energy source – sunlight – but change this into different energy forms: heat energy in the case of solar thermal panels, and electrical energy in the case of photovoltaic panels. Photovoltaic panels have no moving parts – the source of electricity in these types of solar panels is the photovoltaic cells. What do they do?
How do photovoltaic solar panels generate electricity?
An electric current is created when enough electrons are stimulated. Depending on the material, the frequency necessary to trigger the effect can vary. In photovoltaic solar panels, semiconductors are the photoelectric medium used to convert sunlight to 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.
How do photovoltaic cells convert light into electricity?
Photovoltaic cells are based on a related phenomenon called the photovoltaic effect, and they convert light directly into electricity. Let's look at how. Most photovoltaic cells are made of silicon, an element that is at the heart of all modern electronics.
