When was photovoltaic energy storage first proposed

The photovoltaic (PV) effect was first observed by Alexandre Edmond Becquerel in 1839, and the first PV cell with a low efficiency of 6% was developed in 1954, which has now increased to 20%–22%. Examining the history of PV cells can provide valuable insights to guide future developments.

It all began with Edmond Becquerel, a young physicist working in France, who in 1839 observed and discovered the photovoltaic effect — a process that produces a voltage or electric current when exposed to light or radiant energy. A few decades later, French mathematician Augustin Mouchot was inspired by the physicist's work.

In 1966, NASA launched the world's first Orbiting Astronomical Observatory, powered by a one-kilowatt array. In 1973, the University of Delaware was responsible for constructing the first solar building, named "Solar One." The system ran on a hybrid supply of solar thermal and solar PV power.

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.

That same year, a Russian scientist by the name of Aleksandr Stoletov created the first solar cell based on the photoelectric effect, which is when light falls on a material and electrons are released. This effect was first observed by a German physicist, Heinrich Hertz.
