Interfacial and compositional engineering of perovskite solar cells for enhanced device performance and stability

This project was a comprehensive study of interfacial and compositional engineering on perovskite solar cells (PSCs). Significantly enhanced power conversion efficiency and device lifetime of PSC photovoltaic technology were achieved by ion doping based on solution-processed and vapour-assisted treatments. The effects of various amine-contained ligands on enhancing performance of PSC were systematically investigated to reveal controlling defects and interfacial properties in the materials. This work provides several new insights into perovskite solar cells. The research outcomes benefit the development of PSCs based photovoltaic technology
