The electron concentration in an n-type semiconductor is the same as hole concentration in a p-type semiconductor. An external field (electric) is applied across each of them. Compare the currents in them.
No current will flow in p-type, current will only flow in n-type
Current in n-type = current in p-type
current in p-type > current in n-type
current in n-type > current in p-type
