Multiple solar cells assembled together in a single plane form a solar photovoltaic (PV) panel or module. These modules typically feature a glass sheet on the sun-facing side, which allows sunlight to pass through while safeguarding the semiconductor wafers from environmental factors.Component typeActiveWorking principleInventorInvention year1839Watch full videoOverviewA solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of directly into by using the .
