Solar cell efficiency of perovskite solar cells have increased from 3.8% in 2009 [47] to 25.2% in 2020 in single-junction architectures, [48] and, in silicon-based tandem cells, to 29.1%, [48] exceeding the maximum efficiency achieved in single-junction silicon solar cells.
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.
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]
Russell Shoemaker Ohl (January 30, 1898 – March 20, 1987) was an American scientist who is generally recognized for patenting the modern solar cell (U.S. patent 2,402,662, "Light sensitive device"). [1] Ohl was a notable semiconductor researcher prior to the invention of the transistor. [1] He was also known as R.S. Ohl.
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.
Daryl Muscott Chapin [1] (21 July 1906 – 19 January 1995) was an American physicist, best known for co-inventing solar cells in 1954 during his work at Bell Labs alongside Calvin S. Fuller and Gerald Pearson. For this, he was inducted into the National Inventors Hall of Fame in 2008.
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.
After doing little except absorbing $12 million cash, McMaster gave up on the amorphous silicon research, offered to pay back the 57 investors who followed him into solar cells. He then raised yet another $15 million to create Solar Cells Inc. in Toledo OH to work on a different thin-film technology, cadmium telluride photovoltaics. By 1997 ...
