The sunlight that reaches the earth is about 200,000 times the total electrical energy generated by humans everyday
The first working solar cell was invented by Charles Fritts in 1883 and operated at 1% efficiency
The word photovoltaic, the term for a solar cell, comes from the Greek word for light, which is combined with the name Volta, the last name of the scientist after whom the measurement unit volt is named after. All together the word photovoltaic means electricity from light
Every minute, enough solar energy reaches the Earth to meet global energy demands for a year!
