2019 – The world record for solar cell efficiency at 47.1% was achieved by using multi-junction concentrator solar cells, developed at National Renewable Energy Laboratory, Golden, Colorado, USA. [ 43 ] [ additional citation(s) needed ] This is above the standard rating of 37% for polycrystalline photovoltaic or thin-film solar cells as of 2018.
A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
There, with support from Bill Yerkes, he invented the first terrestrial solar cell in 1972 and developed the process of screen-printing cells on solar panels, which is still used in the market today. [3] The company was purchased by Hughes Aircraft in 1975, and the terrestrial division was closed. Shahryar founded his own company, Solec ...
Alexandre-Edmond Becquerel (French: [ɛdmɔ̃ bɛkʁɛl]; 24 March 1820 – 11 May 1891), [1] known as Edmond Becquerel, was a French physicist who studied the solar spectrum, magnetism, electricity and optics. In 1839, he discovered the photovoltaic effect, the operating principle of the solar cell, which he invented in the same year.
It has been speculated that Cove may have invented a photovoltaic panel 40 years before Bell Labs did in 1950. [10] Sugandha Srivastav of the University of Oxford has noted that the use of fossil fuels grew significantly across the globe in those forty years, arguing that "avoiding a 40 year break in solar power’s development could have spared the world huge amounts of carbon emissions."
NASA used solar cells on its spacecraft from the beginning, their second successful satellite Vanguard 1 (1958) featured the first solar cells in space. Solar cells were first used in a prominent application when they were proposed and flown on the Vanguard satellite in 1958, as an alternative power source to the primary battery power source ...

Frank Shuman (/ ˈ ʃ uː m ə n /; January 23, 1862 – April 28, 1918) was an American inventor, engineer and solar energy pioneer known for his work on solar engines, especially those that used solar energy to heat water that would ...
Mária Telkes (December 12, 1900 – December 2, 1995) was a Hungarian-American biophysicist, engineer, and inventor who worked on solar energy technologies. [1]She moved to the United States in 1925 to work as a biophysicist.
