PhD Overview

Hybrid organic-inorganic halide perovskites are a group of materials for highly efficient solar cells. Perovskite absorber material is important for top cells in tandem solar cells with crystalline silicon as bottom cell. Electronic properties of CH3NH3Pb(I1-xBrx)3 perovskites depend on crystallization and defect formation and are crucial for the performance and stability of solar cells. The band gap (Eg), exponential tail states (Et) and the diffusion length (L) are decisive parameters for absorbers in solar cells since they determine photo-generation and Fermi-level splitting. Therefore, Eg, Et and L of CH3NH3Pb(I1-xBrx)3 perovskites were studied with respect to stoichiometry, interfaces, degradation and temperature.
