Please see the following seminar notice reminder for tomorrow: MATERIALS SCIENCE AND ENGINEERING SEMINAR Photopatterning of P3HT for Organic Solar Cells By Lisa Murray Purdue MSE Prelim 1 Advisor- Prof. Kendra Erk ABSTRACT Organic photovoltaics have potential to be a sustainable and low cost energy source if they can achieve greater efficiencies and be scaled up for mass production. Manufacturing in bulk may be achievable with photopatterned organics due to the ease of processing and their potential for improving device performance through fabrication of different active layer morphologies. Patterned films of poly(3-hexyl thiophene) (P3HT) crosslinked by UV light are of particular interest for solar cells due to their solvent compatibility and their ability to form nano-sized features. Photolithography of P3HT may be configured to produce an ordered heterojunction, a morphology that can optimize charge separation and transfer. Experiment designs will be presented for studying photopatterned P3HT ordered heterojunctions in terms of how the lithographic processing impacts efficiency and durability.
