Stabilizing and passivating halide perovskites with amorphous materials
The search of new materials is an important way to address climate change. Engineered materials make up a large part of the world we live in. They determine how we generate and use energy, and are a large source of greenhouse gas emissions and pollution, both at the stage of fabrication, during usage, and at their end of life. Therefore, we should research materials that can aid in supplying the energy and material demands of the future in an energy and material efficient manner.
The material class under investigation in this thesis is halide perovskite. These colorful, semiconducting materials are promising candidates for a wide variety of applications, such as solar cells or lighting. They are brightly luminescent, and the color at which they absorb and emit light can be altered by using different ions as building blocks in their crystalline structure.
To balance all great aspects of halide perovskites, they also have significant downsides. They are unstable when they come into contact with common environmental factors such as water or heat, and due to the presence of lead in the most popular halide perovskite compositions, they are toxic. These downsides need to be addressed before perovskites can be widely used.
This thesis is aimed to address the instability and improve the material quality, by combining them with amorphous, transparent materials
