Solar technology isn't a recent discovery. Its history dates back to the seventh century B.C. when a magnifying glass was used to concentrate the sun's rays to make fire.
Fast forward to 1839, French physicist Edmond Becquerel discovered the photovoltaic effect (generating voltage and electric current upon exposure to light) while experimenting with a cell made of metal electrodes in a conducting solution. He saw that the cell produced more electricity when it was exposed to light. Many physicists and scientists contributed to the awareness, introduction and proliferation of solar energy technology, including AeroVironment founder Dr. Paul MacCready, Jr.
