Perovskite materials, despite displaying remarkable properties, suffer from the use of toxic lead and poor stability towards moisture and thermal stresses. These strongly hinder their future development. Recently, a new family of 3D perovskites, deficient in lead and iodide, the d-HPs, has been discovered. They involve large organic cations that circumvent the Goldschmidt tolerance factor. In the present study, we report that a new cation, the iodoethylammonium I-(CH2)2-NH3 + (IEA+), allows the synthesis of d-HP thin films based on the 3D MAPbI3 perovskite. This new compound has been tested for solar cell application. A final power conversion efficiency of 9.54 % was achieved.
