In a single-junction PV cell, only photons whose energy is equal to or greater than the band gap of the cell material can free an electron for an electric circuit. Today's most common PV devices use a single junction, or interface, to create an electric field within a semiconductor such as a PV cell. The current produced is directly dependent on how much light strikes the module. Modules are designed to supply electricity at a certain voltage, such as a common 12 volts system. This electricity can then be used to power a load, such as a light or a tool.Ī number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module. If electrical conductors are attached to the positive and negative sides, forming an electrical circuit, the electrons can be captured in the form of an electric current - that is, electricity. When light energy strikes the solar cell, electrons are knocked loose from the atoms in the semiconductor material. For solar cells, a thin semiconductor wafer is specially treated to form an electric field, positive on one side and negative on the other. Solar cells are made of the same kinds of semiconductor materials, such as silicon, used in the microelectronics industry. The diagram above illustrates the operation of a basic photovoltaic cell, also called a solar cell. During the energy crisis in the 1970s, photovoltaic technology gained recognition as a source of power for non-space applications. Through the space programs, the technology advanced, its reliability was established, and the cost began to decline. In the 1960s, the space industry began to make the first serious use of the technology to provide power aboard spacecraft. It was billed as a solar battery and was mostly just a curiosity as it was too expensive to gain widespread use.

The first photovoltaic module was built by Bell Laboratories in 1954. In 1905, Albert Einstein described the nature of light and the photoelectric effect on which photovoltaic technology is based, for which he later won a Nobel prize in physics. The photoelectric effect was first noted by a French physicist, Edmund Bequerel, in 1839, who found that certain materials would produce small amounts of electric current when exposed to light. When these free electrons are captured, an electric current results that can be used as electricity. Some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. Photovoltaics is the direct conversion of light into electricity at the atomic level.
