Photovoltaic (PV) cells, or solar cells, are semiconductor devices that convert solar energy directly into DC electric energy. In the 1950s, PV cells were initially used for space applications to power satellites, but in the 1970s, they began also to be used for terrestrial applications.
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.
This process is called the photovoltaic effect. Solar cells are essential for photovoltaic systems that capture energy from the sun and convert it into useful electricity for our homes and devices. Solar cells are made of materials that absorb light and release electrons.
However, the most dominant type of PV cell used in large-scale applications is still crystalline silicon, which is the same basic technology as used in the 1970s. This is partially due to the high availability of low-cost silicon PV panels that have prevented new and emerging cell types from gaining a significant presence in the PV market.
Photovoltaic panels are made up of several groups of photoelectric cells connected to each other. Each group of solar cells forms a network of photovoltaic cells connected in a series of electrical circuits to increase the output voltage.
Cell: The basic photovoltaic device that is the building block for PV modules. All modules contain cells. Some cells are round or square, while thin film PV modules may have long narrow cells. Cells are too small to do much work. They only produce about 1/2 volt, and we usually need to charge 12 volt batteries or run motors.
