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

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 more
symmetrical PbI6 octahedron, resulting in obvious improvement in moisture stability under continuous illumination.
