Optoelectronic characterization of perovskite materials and their application in photovoltaics
Ulč, Filip ; Konečný, Martin (referee) ; Klok, Pavel (advisor)
This bachelor's thesis is focused on a detailed correlative study of optoelectronic perovskite materials through advanced measurement techniques employed at the Institute of Physical Engineering. These techniques include surface charge measurement and time-resolved photoluminescence mapping. Currently, there are few publications or articles attempting to analyze optical and electrical processes using more than two techniques simultaneously. Therefore, the aim of this thesis is to expand the knowledge of existing techniques and enhance them by incorporating surface charge analysis (in the dark and under illumination) using Kelvin Probe Force Microscopy (KPFM). The contribution of this work to the study of perovskite materials lies in correlative measurements that provide new insights into the arrangement and movement of charge carriers, which can be utilized in the research of perovskite solar cells.
