The conversion of solar energy into usable electricity begins with photovoltaic (PV) cells, the key component in any panel. Solar cells are constructed from semiconductor materials, typically silicon, and absorb photons from sunlight to generate an electrical current.
Solar energy conversion describes technologies devoted to the transformation of solar energy to other (useful) forms of energy, including electricity, fuel, and heat.
Solar energy originates 93 million miles away in the heart of our star, the Sun. The Sun merges hydrogen atoms into helium through nuclear fusion, releasing vast amounts of power in light and heat. This energy travels through space, reaching Earth as sunlight, a mix of visible light, ultraviolet, and infrared radiation.
Several promising innovations are set to improve the process of solar energy conversion in the U.S.: Perovskite Solar Cells: A new type of solar cell material that promises higher efficiency and lower production costs. Bifacial Panels: Solar panels that can capture sunlight on both sides, increasing energy output.
Solar power is created when solar radiation is converted to heat or electricity. English electrical engineer Willoughby Smith, between 1873 and 1876, discovered that when selenium is exposed to light, it produced a high amount of electricity.
Solar radiation may be converted directly into electricity by solar cells (photovoltaic cells). In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors. (See photovoltaic effect.)
