J. Mater. Chem. A, 2017,5, Pp. 4803–4808. Abstract
We report here the discovery of a fancy interaction between cesium iodide (CsI) and methylamine (CH3NH2) due to the presence of the hydrogen bond. The formed CsI$xCH3NH2 is a liquid phase, which facilitates the large scale fabrication of highly uniform cesium-containing perovskite films with strong (110) preferred orientation by the CH3NH2 gas healing process. With this method, at most 10% nonpolar Cs cations could fully dope into the crystal lattice and extremely enhance the interaction of the inorganic framework with a moresymmetrical PbI6 octahedron, resulting in obvious improvement in moisture stability under continuous illumination.

{An important property of hybrid layered perovskite is the possibility to reduceits dimensionality to provide wider band gap and better stability. In this work,2D perovskite of the structure (PEA)2(MA)n–1PbnBr3n+1 has been sensitized,where PEA is phenyl ethyl-ammonium, MA is methyl-ammonium, and usingonly bromide as the halide. The number of the perovskite layers has beenvaried (n) from n = 1 through n = ∞. Optical and physical characterizationverify the layered structure and the increase in the band gap. The photovoltaicperformance shows higher open circuit voltage (Voc) for the quasi 2D perovskite(i.e.

Abstract The influence of the Schottky contact is studied for hole transport material (HTM) freeCH3NH3PbI3 perovskite solar cells (PSCs), by using drift-diffusion and small signal models. The basiccurrent-voltage and capacitance-voltage characteristics are simulated in reasonable agreement with experimentaldata. The build in potential of the finite CH3NH3PbI3 layer is extracted from a Mott-Schottkycapacitance analysis. Furthermore, hole collector conductors with work-functions of more than 5.5 eV areproposed as solutions for high efficiency HTM-free CH3NH3PbI3 PSCs.
