Abstract

Tao Xu - Professor, Department of Chemistry and Biochemistry, Northern Illinois University. The latest progress in solution process-based organic-inorganic hybrid perovskites solar cells (PSCs) is reshaping the growth pattern of any previous photovoltaic technologies and has raised a storm of research fever. However, despite the success in boosting efficiency of PSCs, it also appears high time to inject an intense dose of cold thoughts into this globally-spreading “perovskite fever”, because PSCs are still facing several critical materials science and environmental challenges including material instability, the use of toxic lead, the use of precious metals as back cathode, as well as some missing puzzle pieces for a comprehensive basic science understanding of in their excellent charge transport and light harvesting properties. In this talk, I will present some of our work on tackling these challenges including the use of nickel as back electrode to replace the costly gold, the effect of ionic dopants on the stability of perovskite materials, as well as our fundamental study to understand the relation between structure and the optoelectronic properties of hybrid perovskite materials using isotope effect and high pressure method.
