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…
Can we use time-resolved measurements to get Steady-State Transport data for Halide perovskites?
Igal Levine, Satyajit Gupta, Achintya Bera +10
Time-resolved, pulsed excitation methods are widely used to deduce optoelectronic properties of semiconductors, including now also Halide Perovskites (HaPs), especially transport p…
Tetragonal CH3NH3PbI3 Is Ferroelectric
Yevgeny Rakita, Omri Bar-Elli, Elena Meirzadeh +7
Halide perovskite (HaP) semiconductors are revolutionizing photovoltaic (PV) solar energy conversion by showing remarkable performance of solar cells made with esp. tetragonal meth…
Temperature-dependent Hysteresis in MAPbI3 Solar Cells
Igal Levine, Pabitra K. Nayak, Jacob Tse-Wei Wang +7
Hysteresis in the current-voltage characteristics of hybrid organic-inorganic perovskite-based solar cells is one of the fundamental aspects of these cells that we do not understan…
Cesium Enhances Long-Term Stability of Lead Bromide Perovskite-Based Solar Cells
Michael Kulbak, Satyajit Gupta, Nir Kedem +4
Direct comparison between perovskite-structured hybrid organic-inorganic - methyl ammonium lead bromide (MAPbBr3) and all-inorganic cesium lead bromide (CsPbBr3), allows identifyin…
Are Mobilities in Hybrid Organic-Inorganic Halide Perovskites Actually 'High'?
Thomas M. Brenner, David A. Egger, Andrew M. Rappe +3
We present an experimental and theoretical viewpoint on the electronic carrier mobilities of typical hybrid organic-inorganic perovskites (HOIPs). While these mobilities are often…
Mechanical Properties of APbX3 (A=Cs or CH3NH3; X=I or Br) Perovskite Single Crystals
Yevgeny Rakita, Sidney R. Cohen, Nir Klein Kedem +2
The remarkable optoelectronic, and especially photovoltaic performance of hybrid-organic-inorganic perovskite (HOIP) materials drives efforts to connect materials properties to thi…
Why Lead Methylammonium tri-IODIDE perovskite-based solar cells requires a mesoporous electron transporting scaffold (but not necessarily a hole conductor)
Eran Edri, Saar Kirmayer, Alex Henning +5
CH3NH3PbI3-based solar cells were characterized with electron beam-induced current (EBIC), and compared to CH3NH3PbI3-xClx ones. A spatial map of charge separation efficiency in wo…
