| Abstract [eng] |
Hybrid perovskites are remarkably attractive because of the exceptional properties they share with inorganic semiconductors. These include a suitable band gap, a large optical absorption coefficient, superior carrier mobility, and impressive diffusion lengths much larger than most other soft materials such as organic semiconductors or colloidal quantum dot solids. In recent years, knowledge of the fundamental processes in hybrid perovskite materials has greatly improved. However, many aspects of charge carrier transport are still poorly understood and need further investigation. In this work, the charge carrier dynamics in various hybrid perovskites with different device architectures were investigated using different time-resolved spectroscopic techniques developed for hybrid perovskites to link ion migration with charge carrier extraction, recombination, and their trapping and mobility parameters. |
