OPUS 20

Project description

The overall goal of this project is to probe the relationship between the structure and composition of the perovskite active layer and its charge transport properties to understand the physical processes that determine the photoresponse of perovskite single crystals (SCs) based photodetector under working conditions. To realize the aims, the additive and compositional engineering will be applied to develop the methods for crystallization of large and high quality perovskite single-crystals. Special attention will be put on the structural and optical characterizations and analysis of defect density, ion motions and activation energy levels in single-crystalline perovskites with the help of electrochemical impedance spectroscopy under different conditions of light and temperature. Finally, the complete photodetectors based on resulting perovskite single-crystals with a planar architecture will be fabricated and specifically characterized. These studies will provide a better understanding of how the changes in structural composition, conduction mechanism and dimensionality will affect the figure-of-merit parameters of resulting photodetectors.
