A solar cell is to be fabricated for efficient conversion of solar radiation to emf using material A. The solar cell is to be mechanically protected with the help of a coating using material B. If the band gap energy of materials A and B are `E_A` and `E_B` respectively, then which of the following choices is optimum for better performance of the solar cell.

A

`E_(A) = 1.5 eV, E_B = 5 eV`

B

`E_A = 1.5 eV,E_b = 1.5 eV`

C

`E_A = 3eV,E_B = 1.5 eV`

D

`E_A=0.5 eV,E_B = 5 eV`
