Question

Draw and explain working of photo diode with graph​

Answer 1

$\huge\boxed{\fcolorbox{orange}{red}{Answer}}</p><p>$

An electrical device that is used to detect and convert light into an energy signal with use of photo detector is Know as a photodiode. The light that falls on it controls the function of pn-junction. Suppose the wavelength is such that the energy of a photon λhν is enough to break a valance bond.
