Effect of Halide Composition on the Photochemical Stability of Perovskite Photovoltaic Materials.
Misra, RK; Ciammaruchi, L; Aharon, S; Mogilyansky, D; Etgar, L; Visoly-Fisher, I; Katz, EA (2016-09-22)The photochemical stability of encapsulated films of mixed halide perovskites with a range of MAPb(I1-x Brx )3 (MA=methylammonium) compositions (solid solutions) was investigated under accelerated stressing using concentrated ... -
Low-Dimensional Organic-Inorganic Halide Perovskite: Structure, Properties, and Applications.
Misra, RK; Cohen, B-E; Iagher, L; Etgar, L (2017-10-09)Three-dimensional (3 D) perovskite has attracted a lot of attention owing to its success in photovoltaic (PV) solar cells. However, one of its major crucial issues lies in its stability, which has limited its commercialization. ... -
A mesoporous-planar hybrid architecture of methylammonium lead iodide perovskite based solar cells
Misra, RK; Aharon, S; Layani, M; Magdassi, S; Etgar, L (Royal Society of Chemistry, 2016-08-22)We report a hybrid mesoporous-planar architecture of methylammonium lead iodide perovskite based solar cells, to combine the benefits of both the mesoporous and planar architectures in a single device. A mesoporous-TiO2 ... -
A solution-processed tetra-alkoxylated zinc phthalocyanine as hole transporting material for emerging photovoltaic technologies
Zanotti, G; Mattioli, G; Paoletti, AM; Pennesi, G; Caschera, D; Maman, N; Visoly-Fisher, I; Misra, RK; Etgar, L; Katz, EA (Hindawi, 2018-11-13)A tetra-n-butoxy zinc phthalocyanine (n-BuO)4ZnPc has been synthesized in a single step, starting from commercial precursors, and easily purified. The molecule can be solution processed to form an effective and inexpensive ... -
Temperature- and Component-Dependent Degradation of Perovskite Photovoltaic Materials under Concentrated Sunlight.
Misra, RK; Aharon, S; Li, B; Mogilyansky, D; Visoly-Fisher, I; Etgar, L; Katz, EA (2015-02-05)We report on accelerated degradation testing of MAPbX3 films (X = I or Br) by exposure to concentrated sunlight of 100 suns and show that the evolution of light absorption and the corresponding structural modifications are ...
