Solar PV Energy Factsheet
Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for
Solar power
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power.
Photovoltaics and electricity
PV cells generate direct current (DC) electricity. DC electricity can be used to charge batteries that power devices that use DC electricity. Nearly all electricity is supplied as alternating
How Solar Cell Works to Produce Electricity from Sunlight
Solar cells are designed to absorb sunlight and generate a small amount of electricity. Multiple solar cells are connected to form solar panels, which can produce higher power outputs.
How does solar power work?
Learn how solar power works, from the photovoltaic effect to AC conversion, with clear explanations of clean, renewable solar energy and panel technology.

OverviewApplicationsHistoryDeclining costs and exponential capacity growthTheoryEfficiencyMaterialsResearch in solar cells
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 using 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, known colloquially as "sol
How do solar cells work?
Just like the cells in a battery, the cells in a solar panel are designed to generate electricity; but where a battery''s cells make electricity from chemicals, a solar panel''s cells generate
Solar cell
Arrays of solar cells are used to make solar modules that generate a usable amount of direct current (DC) from sunlight. Strings of solar modules create a solar array to generate solar power using solar
How Does Solar Work?
Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be
Solar energy
Solar cell When sunlight strikes a solar cell, an electron is freed by the photoelectric effect. The two dissimilar semiconductors possess a natural difference in electric potential (voltage),
How Do Solar Cells Work? Photovoltaic Cells Explained
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
