Title: Imide-Functionalized Polymer Semiconductors for High-Performance
Organic Thin-Film Transistors and Solar Cells

The talk focuses on development of imide-functionalized polymersemiconductors and their device studies in organic thin-film transistors and solarcells. N-type polymer semiconductor achieves electron mobilities greater than 1cm2/Vs, and p-type polymer semiconductor shows hole mobilities greater than 1.0 cm2/Vs. Newly developed p-type polymer semiconductors not only show high hole mobility, but also enhanced device air-stability. Preliminary device tests achieve a power conversion efficiency greater than 6% in inverted polymer solar cells with an open-circuit voltage (Voc) approaching 1.0 V.
