Autor: Ronen Gottesman, Shay Tirosh, Laxman Gouda, Arie Zaban, Petra J. Cameron, Ralf G. Niemann, Jiangang Hu

Publikováno v: Niemann, R G, Gouda, L, Hu, J, Tirosh, S, Gottesman, R, Cameron, P J & Zaban, A 2016, ' Cs + incorporation into CH 3 NH 3 PbI 3 perovskite : substitution limit and stability enhancement ', Journal of Materials Chemistry A, vol. 4, no. 45, pp. 17819-17827 . https://doi.org/10.1039/c6ta05869h

In this study we systematically explored the mixed cation perovskite Csx(CH3NH3)1-xPbI3. We exchanged the A-site cation by dipping MAPbI3 films into a CsI solution, thereby incrementally replacing the MA+ in a time-resolved dipping process and analys

Hybrid organic–inorganic perovskites have been established as good candidate materials for emerging photovoltaics, with device efficiencies of over 22% being reported. There are currently only two organic cations, methylammonium and formamidinium,

“Ionic diode” (or current rectification) effects are potentially important for a range of applications including water purification. In this preliminary report, we observe novel ionic diode behaviour of thin (300 nm) membranes based on a polymer
