The idea to use ferroelectric materials (PZN-PT) came from the fact that the ferroelectric nature could facilitate electric charges accumulation on the interfaces of the solar cell. Thus, it would increase the open circuit voltage V_oc which could reach more than 10 V. This would directly impact the efficiency which is proportional to V_oc, thus hoping to obtain solar efficiency never equaled by the halide perovskites which are less stable and less resistant in aggressive environments. In this work, the solar cells produced gave an exceptional record efficiency of 39.32% with a very high open circuit voltage (V_oc) of 3.50 V, a short-circuit current density (J_sc) of 0.118 mA/cm² and an FF of 0.72 measured in the positive polarization direction under 3825 lux (5.6 W/m²) lighting. The negative polarization direction under 4781 lux (7 W/m2) lightning gave a current density of 2 mA/cm², an open circuit voltage of 2.30 V and an FF of 0.35.
