What is the most common material used in power-generating photovoltaic cells?
- A.Selenium
- B.Silicon (correct answer)
- C.Cadmium sulfide
- D.Indium arsenide
WhySilicon is the most common material used in power-generating photovoltaic cells. Silicon is the most common material used in power-generating photovoltaic cells, the basis for the overwhelming majority of solar panels in practical use today, answer B. Selenium, cadmium sulfide, and indium arsenide are all real photoconductive or photovoltaic materials used in specialized applications, but none of them is the dominant material for power-generation solar cells the way silicon is.
