In April, 1954, researchers at Bell Laboratories demonstrated the first practical silicon solar cell. The story of solar cells goes back to an early observation of the photovoltaic effect in 1839.
At Bell Telephone Laboratories in Berkeley Heights, NJ, Daryl Chapin, with Bell Labs colleagues Calvin Fuller and Gerald Pearson, invented the first practical photovoltaic solar cell for converting sunlight into useful electrical power at a conversion efficiency of about six percent.
The next major achievement was in 1985 when the University of New South Wales achieved 20% efficiency for silicon cells. In 1999, the National Renewable Energy Laboratory collaborated with SpectroLab Inc. to create a solar cell with 33.3% efficiency.
However, solar cells as we know them today are made with silicon, not selenium. Therefore, some consider the true invention of solar panels to be tied to Daryl Chapin, Calvin Fuller, and Gerald Pearson's creation of the silicon photovoltaic (PV) cell at Bell Labs in 1954.
Three samples were treated with the dull plastic coating and tested and one achieved an energy efficiency of nearly six percent in early 1954. On April 25th, 1954, Bell executives presented the ‘Bell Solar Cell’ to the public with a display of cells using only sun power to operate a 21 inch Ferris Wheel.
The New York Times wrote that the silicon solar cell “may mark the beginning of a new era, leading eventually to the realization of one of mankind’s most cherished dreams — the harnessing of the almost limitless energy of the sun for the uses of civilization.”
