2018 - The first dedicated solar panel recycling plant in Europe and "possibly in the world" is opened in France. [42] 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.
Charles Fritts (1850 – 1903 [1]) was the American inventor credited with creating the first working selenium cell in 1883.. According to CleanTechnica, the world's first rooftop solar array, using Fritts' selenium cells, was installed in 1884 on a New York City rooftop. [2]
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 type of photoelectric cell, a device whose electrical characteristics (such as current , voltage , or resistance ) vary when it is exposed to light.
Gerald L. Pearson (March 31, 1905 – October 25, 1987) was an American physicist whose work on silicon rectifiers at Bell Labs led to the invention of the solar cell. In 2008, he was inducted into the National Inventors Hall of Fame.
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]
Charles Fritts installed the world's first rooftop photovoltaic solar array, using 1%-efficient selenium cells, on a New York City roof in 1884. [54] However, development of solar technologies stagnated in the early 20th century in the face of the increasing availability, economy, and utility of coal and petroleum . [ 55 ]
Indoor solar panels have been around for decades. Solar-powered calculators were first introduced in the 1970s, but the limitations of the amorphous silicon cells they rely upon mean they are too ...
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.
