The material used for solar cell should have band gap (A) equal to zero. (B) equal to 0.08 eV. (C) between 1.0 eV to 1.8 eV. (D) equal to 2 eV. (a) D (b) A (c) C (d) B

Answer: (c). Most solar radiation has photon energy around 1.5 eV. Too small a gap wastes energy as heat; too large a gap absorbs few photons. So the band gap should be between 1.0 eV and 1.8 eV, statement C. So the answer is (c) C.

The material used for solar cell should have band gap

(A) equal to zero.

(B) equal to $0.08$ eV.

(D) equal to $2$ eV.

Show answer and solution

Answer: (c)

Most solar radiation has photon energy around $1.5$ eV.
Too small a gap wastes energy as heat; too large a gap absorbs few photons.
So the band gap should be between $1.0$ eV and $1.8$ eV, statement C.
So the answer is (c) C.
