Study of Lead Halide Perovskite Single Crystals
thesisposted on 10.05.2019, 00:34 by WENXIN MAO
Organo-lead halide perovskites (OHPs) have recently emerged as a new class of exceptional optoelectronic materials, which has been used in many applications, including solar cells, light emitting diodes, and photodetectors. However, despite the thorough studies into lead halide perovskites during over past 10 years, there are still many unknowns concerning both the device performance and the stability, which are strongly related to their crystal quality as well as their optoelectronic properties. This thesis reports on the study of perovskite crystal growth and the mechanism of light induced phase segregation and ion migration in mixed halide perovskite materials.
