In a way many physicists played a part in solar cell invention. Today a solar panel can cost as little as 0 50 a watt. F fritts coated the panels with selenium to produce a very weak electric current. The history of solar energy in the golden state spans back to the industry s earliest roots and is a story of steady progress.

Almost 50 years after the photovoltaic effect s discovery in 1883 american inventor charles fritz created the first working selenium solar cell 3though we use silicon in cells for modern solar panels this solar cell was a major precursor to the technology used today. However development of solar technologies stagnated in the early 20th century in the face of the increasing availability economy and utility of coal and petroleum. A brief history of solar panels inventors have been advancing solar technology for more than a century and a half and improvements in efficiency and aesthetics keep on coming solar has had an.
