Enough energy from the sun hits the earth every hour to power the planet for an entire year—and solar photovoltaic (PV) systems are a clean, cost-effective way to harness that power for homes and businesses. The literal translation of the word photovoltaic is light-electricity—and this is exactly what photovoltaic materials and devices do—they convert light
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.
With the foundation laid in the realm of semiconductor physics, the chapter navigates towards the tangible manifestations of PV technology—photovoltaic cells. These cells, the building blocks of solar panels, come in various forms, each with its unique characteristics and applications.
The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating.
A grid-connected photovoltaic system, or grid-connected PV system is an electricity generating solar PV power system that is connected to the utility grid. A grid-connected PV system consists of solar panels, one or several inverters, a power conditioning unit and grid connection equipment.
Some large photovoltaic power stations such as Solar Star, Waldpolenz Solar Park and Topaz Solar Farm cover tens or hundreds of hectares and have power outputs up to hundreds of megawatts. A small PV system is capable of providing enough AC electricity to power a single home, or an isolated device in the form of AC or DC electric.
A third type of photovoltaic technology is named after the elements that compose them. III-V solar cells are mainly constructed from elements in Group III—e.g., gallium and indium—and Group V—e.g., arsenic and antimony—of the periodic table. These solar cells are generally much more expensive to manufacture than other technologies.
