A comprehensive theory of the physical picture of a p-n junction under all injection conditions has been presented in this paper. The pn product in a junction must always be < . By incorporating all suitable modification of the boundary conditions, the inconsistencies concerning the relation of the applied potential difference to the difference across the space charge region of a p-n junction were observed. Attempt were made to remove those inconsistencies. The transition region for abrupt p-n

The p-n junction is solved by using three-region approach and analytical solutions are derived for low, medium and high injections.
