Title: Ultraflexible and Stretchable Organic Thin-film Transistors and Photovoltaic Cells

Abstract: We report recent progress of ultraflexible organic photovoltaic cells and thin-film transistors that are manufactured on ultrathin plastic film with the thickness of 10 ?m or less. First, we have demonstrated polymer based photovoltaic devices on plastic foil substrates less than two ?m thick, with equal power conversion efficiency to their glass-based counterparts. They can reversibly withstand extreme mechanical deformation and have unprecedented solar cell specific weight. Instead of a single bend, we were able to form a random network of folds within the device area. We have also manufactured organic transistors on ultrathin plastic films in order to achieve sharp bending radius less than 50 microns. Bending cycle experiments will be presented to show the mechanical durability. Finally, future prospects and remaining issues of ultrathin organic electronics will be discussed.

All seminars are held on Wednesdays from 12:00 noon-1:00 p.m. in the Bowen Hall Auditorium Room 222. A light lunch is provided at 11:30 a.m. in the Bowen Hall Atrium immediately prior to the seminar.
