Semiconductor Electronics question

2005 · Q151

NEETPhysicsSemiconductor ElectronicsMCQ+4 / −1
In a p-n junction photo cell, the value of the photo-electromotive force profuced by monochromatic light is proportional to
  1. A
    The barrier voltage at the p-n junction.
  2. B
    The intensity of the light falling on the cell.
  3. C
    The frequency of the light falling on the cell.
  4. D
    The voltage applied at the p-n junction.
View written solutionFree

Correct answer: B

Electromotive force depends on intensity of light that falls on it and does not depend on the frequency.
