As we learnt in 

P -N junction as diode -

It is a one way device. It offers a low resistance when forward biased and high resistance when reverse biased.

- wherein

R = 0, Forward 

\rightarrow \infty Reverse

 

 Do to reverse biasing potential barrier increases but it has no effect on number of charge carrier.
