Emerging perovskite materials are routinely studied as nanostructures, polycrystalline films, or single crystals and have opened up new pathways for optoelectronic device designs (e.g. photovoltaics). Combining perovskite materials with other nanostructures or bespoke charge selective contact layers has also proven beneficial to both performance and building fundamental understandings of their operation in photovoltaics and beyond (Figure 1). Herein, we discuss a variety of perovskite structures and device architectures with an emphasis on understanding their surface chemistry as well as interfacial interactions between the light-absorbing materials and their contacts.1-4 Additionally, experimental techniques that will facilitate the measurement of charge carrier dynamics at both the surface of the materials, as well as at the interface, will be discussed.
