When a hole diffuses from a p-region to the n-region it
- becomes a minority carrier in the n-region.
- lowers the potential barrier.
- raises the potential barrier.
Explanation from PART66Online
As holes diffuse from the P-region into the N-region and recombine, they leave behind uncovered negative acceptor ions on the P-side and add positive charge on the N-side. This build-up of immobile charge strengthens the depletion-region field, raising the potential barrier that opposes further diffusion until equilibrium is reached.

Does that mean current flows through forward biased?
If then, is it right to lower the potential barrier?
Of course, If reverse biased flows, raise the potential barrier.
