A solar cell, also known as a 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 type of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules
Electricity is energy used to perform work, like running your appliances or charging an electric vehicle. Solar energy harnesses photons, which are energy in the form of light, and uses photovoltaic panels ("photo" meaning light and

The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short. Solar PV systems generate electricity by absorbing sunlight and using that light energy to create an electrical current.
Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. Source: National Renewable Energy Laboratory (copyrighted)
This current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce. That's the basic process, but there's really much more to it. Next, let's take a deeper look into one example of a PV panel: the single-crystal silicon panel.
Solar PV systems generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many photovoltaic cells within a single solar module, and the current created by all of the cells together adds up to enough electricity to help power your home.
The best solar cells can wring out nearly half that light energy as electricity. It happens like this: A photon from the sun strikes the solar panel's photoactive layer, which "knocks" an electron out the far side of the panel. This is possible because solar panels use semiconductors to transform light into electricity.
Photo: Solar cells aren't the only way to make power from sunlight—or even, necessarily, the best way. We can also use solar thermal power (absorbing heat from sunlight to heat the water in your home), passive solar (designing a building to absorb sunlight), and solar collectors (shown here).
