Hybrid-Halide Compounds for Thin-Film Electronics is coming at 02/12/2018 - 4:00pm
LPSC 125 Mon, 02/12/2018 - 4:00pm John Labram Assistant Professor,, Electrical Engineering and Computer Science, Oregon State University Abstract: Organo-metallic hybrid perovskites have recently (re)-emerged as a class of materials possessing properties which are, by many-metrics, extraordinary. Not only has the peak reported photovoltaic (PV) cell power conversion efficiency increased at an unprecedented rate; to a value now in excess of that of polycrystalline silicon, but these are compounds processable from solution, at low-temperature (< 100°C), and from inexpensive precursor materials. Despite the progress made in PVs (and to a lesser extent, light-emitting diodes) over the last few years, there has been a notable absence of thin-film transistors (TFTs) based on these compounds in the literature. This is surprising because these compounds possess high charge-carrier mobilities (~100 cm2/Vs), easily-accessible valence and conduction bands, and have clear potential applications in low-cost opto-electronics. In this talk I describe how to develop electronics from these compounds and outline a roadmap for low-cost flexible electronics based on this new class of materials.
