Intriguing functionalities of emerging metal halide perovskites (MHPs) have led to further exploration of this material for sustainable and scalable optoelectronic applications. However, the chemical complexities in precursors result in uncontrolled phase heterogeneities in these materials, which compromises optoelectronic performances. Yet, little of their origin has been understood due to the large chemical space and processing space. We implement a high-throughput automated synthesis-characterization-analysis workflow to explore the massive physicochemical spaces of MHPs. In this presentation, we demonstrate how this automated experimentation efficiently allows for a comprehensive understanding of the complex materials systems including their phase emergence and behaviors, which are directed to the optoelectronic performances. This significantly accelerates materials discoveries and processing optimizations while providing fundamental insights into complex materials systems.
