Answer: Solar panels are made up of silicon cells. This because silicon has high ability for conduction and this make it to be able to convert sunlight into electricity. It is in solar cells has impurities and great chemical properties which make it to be to convert sunlight to electricity.
Silicon
Explanation:
Silicon is an element with atomic number 14, it is a non metal and crystalline solid. It has blue grey metallic lustre. Silicon is made with impurities in solar cells and has special chemical properties to convert sunlight into electricity. It is a semiconductor, a material that can act as a conductor and insulator.
When light interact with silicon cells, it make electrons to be in motion and initiate the flow of electricity, it is called photovoltaic effect.
Silicon alone is not used, it used with metal casing and wiring to ensure proper electric flow.
