My mistake, make that p-doped. Anyway, from the pure "electrons and holes" view the diode is actually electrons(metal), electrons (silicon), holes(silicon), electrons(metal). So electrons-holes-electrons. No explanation for the asymmetric behaviour.

Perhaps you are thinking of the Schottky barrier. (Curioisly though, in the Schottky diode they typically do use the n-doped silicon, although the p-type also forms the Schottky barrier with metals.)
