Today, Yesterday & Tomorrow

ANCIENT TIMES
The ancient Greeks used passive solar methods to take advantage of the heat from the sun in the building of their houses & the Romans used glass windows to trap the warmth of the sun in their homes.  Socrates wrote, "In houses that look toward the south, the sun penetrates the portico in winter."

EDMOND BECQUEREL 1838
In 1838, French Physicist, Edmond Becquerel (bek-uh-rel) discovered the photovoltaic effect – noting that certain materials, when exposed to sunlight generated an electric current. And then, in 1883, Charles Fritts developed the first primitive solar cell by depositing selenium on a thin layer of gold.

ALBERT EINSTEIN 1905
In 1905, Albert Einstein described the nature of light and the photoelectric effect, on which photovoltaic technology is based; he later won a Nobel prize in physics for his discoveries.

Birth of Modern PV - 1940's
In the 1940's, the modern photovoltaic cell was developed by Russell Ohl of Bell Laboratories. In 1954 Bell released a photovoltaic device billed as a solar battery, it was mostly just a curiosity, but it was then that people started to grasp the real potential of solar electricity. Today, we have everything from solar-powered buildings to solar powered vehicles.
