International audienceIn this paper, we propose a description of the Rashba and Dresselhaus effects in hybrid organic-inorganic perovskites (HOP). We recall how the loss of the inversion symmetry together with spin-orbit coupling leads to the loss of the spin degeneracy, effect known as the Rashba and/or Dresselhaus effect depending on the resulting symmetry. This phenomenon is exemplified with formamidinium tin iodide CH(NH2)2SnI3 where both Rashba and Dresselhaus effects are present. We show that this effect can be controlled by temperature, as observed for the 2-dimensional HOP Bz2bCl4 (Bz = benzylammonium). On the other hand, an applied external electric field can also tune the amplitude of the spin-splitting as shown on the 3-dimensional HOP CH3NH3PbBr3
