Characterization Methods and Technologies for Halide Perovskite Materials and Devices

Summary

This chapter discusses a range of characterization methods that facilitate a deeper understanding of mesoscopic perovskite solar cells (PSCs). It begins with methods to study the layer quality of the mesoscopic contact cell before perovskite filling. The chapter introduces the necessary methods to study chemical–physical material and crystal properties and presents their applicability to mesoscopic PSC. This is followed by discussion of spatially‐resolved photophysical methods such as photoluminescence imaging, which are typically carried out when the system is in steady‐state. In PSCs, the opportunity to examine the layered form helps in the detailed investigation of the perovskite layer after its fabrication. Microscopically resolved optoelectronic methods provide spatial information on the fundamental physical properties of the solar cell. The I–V characteristic represents the most important measured property of a solar cell from the application point of view.
