This research project focuses on the development and in-depth characterization of multiporous carbon electrode matrices for perovskite-based optoelectronic devices, specifically solar cells and memristors. The aim is to investigate how the tailored microstructure of carbon electrodes, the interfaces and perovskites composition influences charge transport, ion migration, and hysteresis behavior in the devices. The multiporous carbon architecture is engineered to provide high surface area, improved interfacial contact with the perovskite layer, and enhanced pathways for charge extraction, while also acting as a barrier to moisture and oxygen ingress. To evaluate the impact of the carbon matrix on device operation, an array of advanced characterization techniques will be employed to assess optoelectronic properties, crystallographic structure, and carrier dynamics. This includes current-voltages sweeps, tapered cross-section kelvin probe measurements and time resolved spectroscopic measurements to entangle electronic and ionic charge migration. The findings of this project are expected to provide critical insights into engineering strategies for controlling hysteresis, improving stability, and enabling functional device applications that are tailored for application in solar cells and memristors.
