The conversion of light into energy using semiconducting materials that show the photovoltaic effect, a phenomenon investigated in physics, photochemistry, and electrochemistry, is known as photovoltaics (PV). PV technologies use a solid-state technology with practically little energy storage to transform a highly cyclical, variable, and sometimes unpredictable solar supply with no inherent storage into electricity. Solar power generation relies heavily on photovoltaic technologies. The importance of photovoltaic technology in long-term power generation has been recognized. During the past decade, photovoltaic technology has advanced at a breakneck pace. Photovoltaics are currently the energy source of choice for remote power needs and emergency power needs, even when grid electricity is available.
