Using HPC to Optimize Molecular Design and Materials Processing for High-Mobility Materials for Solar Cells & OTFTs

The market outlook for organic electronic materials suggests that sales will reach about $15 billion in the next 10 years, according to a December 2007 NanoMarkets report entitled "Organic Harvest: Opportunities in Organic Electronic Materials." Much of this market will come from RFID tags, display backplanes and OLED (organic light emitting diode) displays and lighting. The market for hybrid organic-inorganic semiconductor materials is also likely to grow rapidly for solar cell applications. Unfortunately, growth in this market is currently hampered by the unguided design of organic semiconductor materials with superior electrical properties. They are also hindered by the need to develop scaleable processes that lend themselves to mass production. Roll-to-roll production is one example of a high-volume low-cost approach. Ironically, the key advantage of using organic molecules, their "tenability" by chemical constitution, is also an issue. Experimentally exploring and evaluating promising candidate materials from this incredibly large parameter space is daunting. We will show how high-performance computing offers a viable means to tackle this problem and suggest which classes of materials are likely to have the best performance and to suggest how to optimize manufacturing processes by suggesting conditions that lead to materials with desirable properties.


Paulette Clancy is serving her second term as the Director of the School of Chemical and Biomolecular Engineering at Cornell University. She is the first female Director of the School and the first woman to Chair an Engineering department in the history of the College of Engineering at Cornell. A native of London, England, she graduated with First Class Honors from London University and received a D. Phil in Chemistry from Oxford University. After post-doctoral research at Cornell and at London University, she joined the faculty at Cornell in 1987. Her research laboratory is one of the leading groups in the country studying atomic- and molecular-scale modeling of semiconductor materials and materials processing. Her team focuses on the prediction and insight that they can provide regarding the link between the choice of material and its subsequent properties, allowing them to suggest processing conditions and tailored materials to fulfill a desired set of constraints. She has played an active role as an advocate for increased representation of women among physical scientists and engineers. She is the founding Chair of the Women in Science and Engineering (WISE) faculty in the College of Engineering at Cornell and an original co-writer of what became the Cornell policy for family leave. In 2003, she won the James M. and Marsha D. McCormick award for excellence in undergraduate advising; in 2005 the Alice Cook award for services to promoting women in science at Cornell. In 2007, she won the Zellman Warhaft award for the promotion of diversity in the College of Engineering. In 2008, she won Cornell's highest award for mentoring, the Kendall Carpenter award. In July 2008, she gave a plenary lecture at a Gordon conference on organic electronics. In 2009, she will be the first NSF Advance Lecturer at Iowa State University.
