The development of solar cell technology, or photovoltaic (PV) technology, began during the Industrial Revolution when French physicist Alexandre Edmond Becquerellar first demonstrated the photovoltaic effect, or the ability of a solar cell to convert sunlight into electricity, in 1839. About four decades later,. .
