Solar photovoltaic (PV) is the generation of electricity from the sun's energy, using PV cells. A Solar Cell is a sandwich of two different layers of silicon that have been specially treated so they will let electricity flow through them in a specific way. A Solar Panel is made up of many solar cells.
Photovoltaic technology, often abbreviated as PV, represents a revolutionary method of harnessing solar energy and converting it into electricity. At its core, PV relies on the principle of the photovoltaic effect, where certain materials generate an electric current when exposed to sunlight.
We delve into the photovoltaic effect, which is at the heart of solar cell functionality, converting sunlight directly into electrical energy. The basic structure and operation of solar cells are elucidated, including the role of semiconductor materials and their interaction with incident light to generate electron–hole pairs.
To comprehend the intricate choreography of the photovoltaic effect, one must first grasp the fundamental concepts of solar radiation and semiconductor physics. Solar radiation, the radiant energy emitted by the sun, serves as the primary source of energy for PV systems.
A solar cell is a type of photoelectric cell which consists of a p–n junction diode. Solar cells are also called photovoltaic (PV) cells. An intrinsic (pure or undoped) semiconducting material like silicon (Si) or germanium (Ge) does not contain any free charge carriers.
Solar PV cells, modules, and systems. The solar cell includes a front contact grid made of silver. For solar cells and PV modules, the typical size and power capacity are indicated. PV systems comprise an array of PV modules. The elements shown in orange are optional and depend on the specific system configuration.
