Solar panels convert light energy from sunlight into electrical energy. What material is most likely used in solar panels, and why?


A.) A nonmetal is used because it is a semiconductor and can become more conductive when more light shines on it.


B.) A metalloid is used because it is a good conductor but can become less conductive when more light shines on it.


C.) A metalloid is used because it is a semiconductor and can become more conductive when more light shines on it.


D.) A nonmetal is used because it is a poor conductor but can become more conductive when more light shines on it.
