Answer and Explanation :-

Answer: Option 2


Silicon is what is known as a semi-conductor, meaning that it shares some of the properties of metals and some of those of an electrical insulator, making it a key ingredient in solar cells. Silicon is used to make Photovoltaic cells. The Solar cells that we see on calculators and satellites are also called Photovoltaic (PV) cells, which as the name implies (photo meaning 'light' and voltaic meaning 'electricity'), convert sunlight directly into electricity.
