Coordination engineering toward high performance organic–inorganic hybrid perovskites

• Preparation of organic–inorganic hybrid perovskites.
• Effects of various factors such as atmosphere, moisture content and solvents on the microstructure and optoelectronic properties.
• Insights into the degradation mechanisms and stability improvements.
• Introduction to intermediate complexes.

In this review we present how engineering of the coordination sphere of group IV transition metals allows to tune the structure and properties of organic–inorganic hybrid perovskite materials and offer an overview of the preparation of organic–inorganic hybrid materials. The effects of various factors such as temperature, atmosphere, moisture content and solvent of precursor on the microstructure and optoelectronic properties are addressed. Review of the literature on the degradation and stability provides insight into the degradation mechanisms and stability improvement of hybrid perovskite materials. So-called “intermediate complexes” are commonly formed in solution-processed perovskite materials and are used as a route for the production of perovskite films with optimized morphologies and properties.
