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 ...
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.
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]
Pearson informed Chapin of this discovery, prompting him to switch materials and after a year the functional solar cell was demonstrated on 25 April 1954. [3] [6] The solar cells delivered a power of about 60 watts per square meter, for an efficiency of 6 percent, and was patented as a "solar energy converting apparatus". [7] [8]
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 ...
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 ...
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]
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]
