Meeting our future global energy needs in an environmentally responsible way is one of the greatest challenges in the twenty first century.  The discovery of new functional materials is critical to developing the needed disruptive technologies for energy conversion, delivery, storage, and use.  Remarkable advances in theory and high-throughput materials synthesis/characterization are enabling theory to guide experimental materials development.  This seminar will focus on materials by design research from the Next Generation for Materials by Design (CNGMD) Energy Frontier Research Center (EFRC).  Our objective is to discover and synthesize novel functional materials in a predictive manner through multiple-property search, incorporation of metastable materials into predictive design, and the development of theory to guide materials synthesis. Our approach integrates detailed high-throughput experimental studies and advanced in-situ characterization methods with a computational design environment involving high throughput as well as detailed theoretical studies along with data mining.   Our main goal is to develop a systematic methodology to incorporate and actively design for functional metastability.  Another aim is to guide the synthesis of new materials.  We focus on inorganic semiconductor materials with desired optoelectronic properties for solar energy conversion and related technologies.  An overview of NREL’s extensive R&D program in photovoltaics to meet the US Department of Energy Sunshot goals will also be presented along with challenges to address the development of the needed terawatts of global solar energy.
