In a $p-n$ junction photocell, the value of the photo electromotive force by monochromatic light is proportional to:
  1. the barrier voltage at the $p-n$ junction
  2. the intensity of the light falling on the cell
  3. the frequency of the light falling on the cell
  4. the voltage applied at the $p-n$ junction

Solution

In a p-n function photo cell, the value of the photo electromotive force produced by monochromatic light is proportional to the intensity of the light falling on the cell.
