Humans first directly harnessed solar power in the 7th century B.C. when they used a magnifying glass to concentrate the sun's rays to make fire12. Later, in the 3rd century B.C., the Greeks and Romans were known to harness solar power with mirrors to light torches for religious ceremonies1. The first solar device to produce electricity from sunlight was installed on a rooftop in New York in 1883 by American inventor Charles Fritts2. The development of solar cell technology began during the Industrial Revolution when French physicist Alexandre Edmond Becquerellar first demonstrated the photovoltaic effect in 18393.
