Dopants are not the same in heavily doped semiconductors. For higher mobility dopants should be on the anion site for n-type and the cation site for p-type semiconductors, as these dopants are less disruptive to the band for the majority charge carriers.

High-efficiency perovskite solar cells typically employ an organic-inorganic metal halide perovskite material as light absorber and charge transporter, sandwiched between a p-type electron-blocking organic hole-transporting layer and an n-type hole-blocking...
Over the past several years, organic–inorganic hybrid perovskites have gained considerable research attention due to their direct band gap, large absorption coefficient, ambipolar diffusion and long carrier diffusion length, and have revolutionized the prospects of emerging photovoltaic technologies, with the highest power conversion efficiency of over 19% achieved under laboratory conditions.
