Question
What should be the approximate band gap of the semiconductors to be used as solar cell materials?a.1.3 eVb.0.08 eVc.0.45 eV
Solution
The ideal band gap of the semiconductors to be used as solar cell materials should be approximately 1.3 eV. This is because a band gap of this value allows the semiconductor to absorb a large portion of the solar spectrum. Lower band gaps would result in lower energy photons not being absorbed, while higher band gaps would result in less overall absorption. Therefore, the correct answer is a. 1.3 eV.
