In a p-n junction photocell, the value of the photo electromotive force by monochromatic light is proportional to:

Options

  1. Athe barrier voltage at the p-n junction
  2. Bthe intensity of the light falling on the cell
  3. Cthe frequency of the light falling on the cell
  4. Dthe voltage applied at the p-n junction

Correct answer

B. the intensity of the light falling on the cell

Step-by-step 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.
