The element required for Solar energy conversion?

  • A.Silicon
  • B.Beryllium
  • C.Ultra pure carbon
  • D.Tantalum

Answer: A

Silicon is the element used to convert solar energy to electricity. A photovoltaic cell is a silicon wafer doped to make a p-n junction; light striking it frees electrons that flow as current.

Silicon is used because its band gap of 1.1 eV suits the solar spectrum well and because it is abundant and easily purified.
