Photovoltaics - an overview | ScienceDirect Topics

A few years later, Charles Fritts, an American inventor, created the first working photovoltaic cell when he built junctions by spreading a thin layer of selenium on a metal plate and covering it with an ultra-thin, nearly transparent layer of gold (1883). The cell was only about 1% efficient.

Who invented solar panels? - Who Invented?

The solar cell creation for the first time is credited to Charles Fritts, who used junctions that were created when the semiconductor was coated by a very thin layer of gold. The earliest solar cells and panels that were created were extremely inefficient and the energy conversation received from the sun stood under 1%.
