Congratulations to the First Chemistry of Materials Lectureship and Best Paper Award Winners!

Chemistry of Materials and the Division of Inorganic Chemistry (DIC) of the American Chemical Society are very proud to announce the winners of our inaugural Chemistry of Materials lectureship. The lectureship highlights and celebrates not only creative and high-quality science, but also the contributions of the team to the research. We are proud to announce that the winners of the first Chemistry of Materials lectureship are Kai Zhu (PI, corresponding author) and Zhen Li (first author, post-doc) of the National Renewable Energy Laboratory (NREL). Zhu, Li, and co-workers co-authored “Stabilizing Perovskite Structures by Tuning Tolerance Factor: Formation of Formamidinium and Cesium Lead Iodide Solid-State Alloys.” The paper is an outstanding piece of work that applies fundamentals of solid state science to understand the source of instability of these materials. The central importance of the tolerance factor, as described in this paper, enables the tailoring of the stability of the lead-halide perovskites through solid state alloying, thus providing a critical insight to enable their application for stable photovoltaic applications.

The award winning team will present their paper at the 254th American Chemical Society National Meeting & Exhibition in Washington, DC August 20-24, 2017.

The perovskite team at the National Renewable Energy Laboratory (NREL) has devoted immense efforts on perovskite photovoltaic (PV) research, covering material synthesis, interface design, device physics, fundamental characterizations, scalability and stability issues related to perovskite materials and solar cells. The team is aiming to push perovskite-based materials and technologies with an emphasis on creating a foundation for bringing perovskite PV to market. The team intensely collaborates with leading research groups in the US and internationally with different expertise to deepen fundamental understandings of the issues and challenges associated with perovskite materials and devices.
