To forward bias the p-n junction, the p side is made more positive, so that it is "downhill" for electron motion across the junction.An electron can move across the junction and fill a vacancy or "hole" near the junction. It can then move from vacancy to vacancy leftward toward the positive terminal, which could be described as the hole moving right.
