Zusammenfassung

Halide perovskites have recently emerged as a class of promising semiconductors for efficient device applications, especially solar cells and light-emitting diodes. Their unique combination of optoelectronic properties and their impressive defect tolerance, despite low temperature, wet-chemistry synthesis, are unprecedented among functional materials. It has been suggested, but not yet clear, that the interaction of electrons with the soft ionic lattice lies at the heart of their peculiar properties. Qualitatively different models for the description of the electron-lattice interaction...
