Assemblies of solar cells are used to make solar modules that generate electrical power from sunlight, as distinguished from a "solar thermal module" or "solar hot water panel". A solar array generates solar power using solar energy. Application of solar cells as an alternative energy source for vehicular applications is a growing industry.
Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as "solar panels". Almost all commercial PV cells consist of crystalline silicon, with a market share of 95%. Cadmium telluride thin-film solar cells account for the remainder.
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.
The current produced in a solar cell is directly proportional to the intensity of radiation and is governed by the photoelectric effect, i.e., with an increase in the intensity, the current increases. However, an increase in the temperature of the solar cell reduces its voltage.
When solar energy hits solar cells, the electrons in the materials are freed and can be induced to travel through an electrical circuit. This direct current (DC) can power electrical devices or be sent to the grid. Solar cells produce DC, which is then converted to alternating current (AC) by using an inverter.
