Nicholas Anderson - Dallas TX, US

International Classification:

C07F 7/24
H01L 51/05
H01L 51/42

Abstract:

A perovskite material that has a perovskite crystal lattice having a formula of CMX, where x, y, and z, are real numbers. Bulky organic cations reside near a surface or a grain boundary of the perovskite crystal lattice. C includes one or more cations selected from the group consisting of Group 1 metals, Group 2 metals, methylammonium, formamidinium, guanidinium, and ethene tetramine. M includes one or more metals each selected from the group consisting of Be, Mg, Ca, Sr, Ba, Fe, Cd, Co, Ni, Cu, Ag, Au, Hg, Sn, Ge, Ga, Pb, In, Tl, Sb, Bi, Ti, Zn, Cd, Hg, and Zr and combinations thereof.
