Optimization of perovskite solar cells through interfacial, architectural, and solution-based modifications
MetadataShow full item record
The photovoltaic performance of perovskite solar cells is extremely dependent on the crystallization, morphology and interfacial characteristics of the thin films utilized in the device, which are affected by a multitude of factors. In this work, I explore routes to optimize device performance through optimizing the perovskite crystallization and morphology via doping and processing, tailoring the architecture, or optimizing interfaces in the perovskite devices. In addition, one major drawback that prevents the large-scale practical implementation of perovskites is their susceptibility to performance degradation in humid environments. This work will also explore the improvement made to moisture stability. Lastly, this work will explore the various applications of the modified perovskite devices.
