Experimental Evidence for Defect Tolerance in Pb-Halide Perovskites
Naga Prathibha Jasti, Igal Levine, Yishay Feldman +3
The term defect tolerance (DT) is used often to rationalize the exceptional optoelectronic properties of Halide Perovskites (HaPs) and their devices. Even though DT lacked direct e…
The pursuit of stability in halide perovskites: the monovalent cation and the key for surface and bulk self-repair
D R Ceratti, A V Cohen, R Tenne +12
We find significant differences between degradation and healing at the surface or in the bulk for each of the different APbBr3 single crystals (A=CH3NH3+, methylammonium (MA); HC(N…
Type and Degree of Covalence: Empirical Derivation and Implications
Yevgeny Rakita, Thomas Kirchartz, Gary Hodes +1
The way atoms attach to each other defines the function(s), e.g., mechanical, optical, electronic, of a given material. The nature of the chemical bond is, therefore, one of the mo…
Between Structure and Performance in Halide Perovskites for Photovoltaic Applications: the Role of Defects
Yevgeny Rakita, David Cahen, Gary Hodes
My study is about Halide Perovskites (HaPs) and focuses the fundamental structural, chemical and dielectric properties of HaPs in reference to their PV-related properties. * I pres…
