Iodoethylammonium (IEA+)-based lead- and iodide- deficient halide perovskites (d-HPs) for solar cells

Résumé

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.
