The photovoltaic effect: the heart of modern solar energy

The photovoltaic effect, discovered by Frenchman Edmond Becquerel in 1839, is a physical phenomenon that converts light energy, particularly solar radiation, into electrical energy. This principle lies at the heart of the photovoltaic cells that make up solar panels, enabling electricity to be generated from solar energy, the renewable energy with the greatest potential today.
