Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy. These photons contain varying amounts of energy that correspond to the different wavelengths of the solar spectrum. A PV cell is made of semiconductor material.
A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.
That means a solar cell can't produce any more electrical energy than it receives each second as light. In practice, as we'll see shortly, most cells convert about 10–20 percent of the energy they receive into electricity.
A basic rule of physics called the law of conservation of energy says that we can't magically create energy or make it vanish into thin air; all we can do is convert it from one form to another. That means a solar cell can't produce any more electrical energy than it receives each second as light.
An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity. An inverter can convert the power to alternating current (AC). The most commonly known solar cell is configured as a large-area p–n junction made from silicon.
The efficiency that PV cells convert sunlight to electricity varies by the type of semiconductor material and PV cell technology. The efficiency of commercially available PV panels averaged less than 10% in the mid-1980s, increased to around 15% by 2015, and is now approaching 25% for state-of-the art modules.
The Sun has light energy which travels to Earth and is then captured by the solar panels. Other things that give off light energy are lightbulbs, fire, a torch and traffic lights.
