When the P-N Junction is formed, the depletion region gets created and movement of electrons and holes stops. Thus the current flowing through an unbiased P-N Junction is zero.
To make current to flow we have to Bias the P-N Junction Diode. Biasing is the process of applying external DC voltage to the semiconductor diode.
When the external voltage is not applied to the diode, the P-N Junction will remain in the state of equilibrium. Therefore there is no current flowing through it.
To make the current to flow, it is necessary to "Bias" the diode. The biasing can be two types;
[1] Forward Bias
