Consider the following statements:
A. The junction area of solar cell is made very narrow compared to a photo diode.
B. Solar cells are not connected with any external bias.
C. LED is made of lightly doped p-n junction.
D. Increase of forward current results in continuous increase of LED light intensity.
E. LEDs have to be connected in forward bias for emission of light.
Choose the correct answer from the options given below:
  1. B, E Only
  2. B, D, E Only
  3. A, C Only
  4. A, C, E Only

Solution

Clearly statement ' $A$ ' is wrong as for solar cell junction area are mode wide. LED connected in forward biase and its intensity increases upto certain value of current and further there is no charge as intensity saturates.
Also solar cells are not connected with any external bias.
