Strain effects on the optical properties of lead-halide perovskites

In the last decade, lead-halide perovskites have gathered significant attention due to their fascinating optoelectronic properties which make them suitable for a plethora of applications such as solar cells, light-emitting diodes, displays, lasers. The versatility of these materials results from the possibility to tune their properties by directly manipulating their chemical composition and structure. To make full use of this tunability we need to be able to understand the relationship between structure and properties. Thus, in this thesis we investigate how variations in structure resulting from different crystal growth and mechanical stimuli such as application of external pressure can manipulate the optical properties of perovskite thin films.
