Impedance Characteristics of Hybrid Organometal Halide Perovskite Solar Cells,ciples of lead halide perovskite solar cells and their related materials. The main topic of the chapter is the identification of capacitances and their origin, which is related to ion accumulation, electron accumulation, or a combination of both. In addition to impedance spectroscopy, we examine a n

Charge Transport in Organometal Halide Perovskites,ective charge mobility strongly determine whether a material is suitable for a particular application. A clear example is the relative low mobility of organic semiconductors, compared to their crystalline inorganic counterparts, which makes organic semiconductors unsuitable for high-end electronic a

First-Principles Modeling of Organohalide Thin Films and Interfaces,(acting as electron selective contacts in solar cells), exploring different surface terminations and doping by chloride ions. Also the effect of defects at the interface with TiO. is analyzed and their impact on solar cell performance is discussed. Finally, the heterogeneous interface between methyl

We further show that CH.NH.PbI. exhibits an intrinsic ambipolar self-doping behavior with electrical conductivity tunable from .-type to .-type via controlling the growth conditions. However, CH.NH.PbBr. exhibits unipolar self-doping behavior. It demonstrates a preference for .-type conductivit
