Solar panels convert light energy from sunlight into electrical energy. What material is most likely used in solar panels, and why?
A nonmetal is used because it is a semiconductor and can become more conductive when more light shines on it.
A metalloid is used because it is a good conductor but can become less conductive when more light shines on it.
A metalloid is used because it is a semiconductor and can become more conductive when more light shines on it.
A nonmetal is used because it is a poor conductor but can become more conductive when more light shines on it.

A metalloid is used because it is a semiconductor and can become more conductive when more light shines on it.
Example: silicon (a metalloid) is doped to form p–n junctions; photons create electron–hole pairs, increasing conductivity and producing current.
