will present a seminar entitled:
"Polymer Semiconductor-Based
Electronics and Solar Cells"
Abstract:
Advances in the controlled synthesis, processing, and tuning of the properties of conjugated polymer semiconductors promise improvement in the performance of organic semiconductor devices and are accelerating the emerging era of plastic electronics. Polymer semiconductors as bulk thin films, are being exploited in a range of electronic and optoelectronic devices, including light emitting diodes for displays and solid-state lighting, thin film transistors, logic circuits, photovoltaic cells, and sensors. Our laboratory is exploring both molecular and nanoscale engineering approaches to processable and robust, high charge carrier mobility materials for developing the next generation high-performance organic electronics and solar cells. We are investigating the synthesis, processing, multiscale morphology, charge transport, and electronic and optical properties of various classes of polymer semiconductors and their nanostructures. Some recent examples include polymer semiconductor nanowires and assemblies of block copolymers. Polymer nanowires with widths of 5-30 nm and aspect ratios of up to 900, that are readily assembled from solution, have been found to be promising building blocks for high performance transistors and for solar energy applications, including efficient bulk heterojunction solar cells.
