In an unbiased p-n junction, holes diffuse from the p-region to n-region because

In an unbiased p-n junction diode, the holes diffuse from the p-region to the n-region because of the difference in their concentration in the regions. Holes concentration is more in p-region, hence to achieve equilibrium they diffuse towards less concentrated n-region.
