The material used for solar cell should have band gap (a) equal to zero. (b) less than 1.0 eV (non-zero). (c) more than 1.8 eV. (d) between 1.0 eV and 1.8 eV.

Answer: (d). Maximum solar intensity is near photon energy ≈ 1.5 eV. A band gap of 1.0 to 1.8 eV absorbs most of these photons with little waste. So the answer is (d) between 1.0 eV and 1.8 eV.

The material used for solar cell should have band gap

Show answer and solution

Answer: (d)

Maximum solar intensity is near photon energy $\approx 1.5$ eV.
A band gap of $1.0$ to $1.8$ eV absorbs most of these photons with little waste.
So the answer is (d) between 1.0 eV and 1.8 eV.
