Photovoltaic solar energy comes from the conversion of sunlight into electricity in semi-conducting materials like silicon or covered with a thin metal layer. These photosensitive materials have the property to liberate electron under the influence of an external energy. This is the photovoltaic effect.Saturday, July 9, 2011
