Timeline of solar cells

In the 19th century, it was observed that the sunlight striking certain materials generates detectable electric current – the photoelectric effect.

They have historically been used in situations where electrical power from the grid was unavailable.

As the invention was brought out it made solar cells as a prominent utilization for power generation for satellites.

Satellites orbit the Earth, thus making solar cells a prominent source for power generation through the sunlight falling on them.

Solar cells are commonly used in satellites in today's times.

Edmond Becquerel created the world's first photovoltaic cell at 19 years old in 1839.
Einstein's "On a Heuristic Viewpoint Concerning the Production and Transformation of Light" was published in Annalen der Physik in 1905.
