The answer is "A metalloid is used because it is a semiconductor and can become more conductive when more light shines on it."
Solar has entered the standard as the world's least expensive vitality source, leaving numerous individuals considering how sun oriented PV can be so effective and modest while as yet giving "green" vitality.
Solar photovoltaics are made with various segments, the most essential of which are silicon cells. Silicon, nuclear number 14 on the occasional table, is a nonmetal with conductive properties that enable it to change over daylight into power. At the point when light communicates with a silicon cell, it makes electrons be set into movement, which starts a stream of power. This is known as the "photovoltaic effect."
