What does photovoltaic mean? Photovoltaic cells are devices that convert solar energy into electrical energy. When photons from light energy bump into the cell's surface, they trigger an electric current moving electrons from one atom to another.
Photovoltaic solar energy is a method of obtaining electrical energy thanks to solar panels. It is a renewable energy because all energy generated comes from the Sun. For this reason, it is considered inexhaustible, unlike fossil fuels. In addition, we do not emit greenhouse gases by producing electricity using solar cells.
The solar cells are the photovoltaic irrespective of whether the source is sunlight or artificial light, They are used as a photodetector (for example infrared detectors), They detect the light or other electromagnetic radiation near the visible range or They measure the light intensity.
PV cell technology is now a critical component in the renewable energy sector and responsible for generating up to 10% of the world’s electricity in 2021. Photovoltaic cell technology is remarkably efficient in harnessing sunlight, a free, renewable, and non-polluting energy source.
Photovoltaic cell technology is remarkably efficient in harnessing sunlight, a free, renewable, and non-polluting energy source. Photovoltaic cells have a maximum theoretical efficiency of approximately 33%, with the average residential solar panel generating between 200 and 400 watts per hour in optimal conditions.
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
