    2008 - New record achieved in solar cell efficiency. Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have set a world record in solar cell efficiency with a photovoltaic device that converts 40.8% of the light that hits it into electricity. However, it was only under the concentrated energy of 326 suns ...

    en.wikipedia.org/wiki/Solar_cell

    A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] 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.

    In 1839, he discovered the photovoltaic effect, the operating principle of the solar cell, which he invented in the same year. [2] [3] He is also known for his work in luminescence and phosphorescence. He was the son of Antoine César Becquerel and the father of Henri Becquerel, the discoverer of radioactivity.

    As of 2024, the world record for solar cell efficiency is 47.6%, set in May 2022 by Fraunhofer ISE, with a III-V four-junction concentrating photovoltaic (CPV) cell. [ 30 ] [ 31 ] This beat the previous record of 47.1%, set in 2019 by multi-junction concentrator solar cells developed at National Renewable Energy Laboratory (NREL) , Golden ...

    en.wikipedia.org/wiki/Solar_power

    A solar cell, or photovoltaic cell, is a device that converts light into electric current using the photovoltaic effect. The first solar cell was constructed by Charles Fritts in the 1880s. [13] The German industrialist Ernst Werner von Siemens was among those who recognized the importance of this discovery. [14]

    In 1939, Russell Ohl created the solar cell design that is used in many modern solar panels. He patented his design in 1941. [5] In 1954, this design was first used by Bell Labs to create the first commercially viable silicon solar cell. [1] Solar panel installers saw significant growth between 2008 and 2013. [6]

    The United States, where modern solar PV was invented, led installed capacity for many years. Based on preceding work by Swedish and German engineers, the American engineer Russell Ohl at Bell Labs patented the first modern solar cell in 1946. [24] [25] [26] It was also there at Bell Labs where the first practical c-silicon cell was developed ...

    Photovoltaics (PV) were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s.
