Abstract
Materials for Printed, Large-Area Ductile Organic Solar CellsAntonio Facchetti, Georgia Institute of Technology, afacchetti6@gatech.eduAbstractApproved for Public ReleaseThe objective of this hypothesis-driven collaborative effort combining research groups, led by two highly-qualified PIs at Geogia Institute of Technology and Northwestern University is to rationally design, synthesize the component materials of, and to fabricate next-generation printed high-power conversion efficiency (PCE) and stable and light-weight organic solar cells (OSCs) and modules on plastic, as well as on elastic and textile substrates. These would be integrated with large-area, flexible, and portable devices to meet the energy needs of tomorrow#s Naval and Marine operational forces.The approach of this combined two-institution transdisciplinary team builds on established PI expertise in molecular/polymeric rmaterials design, materials processing using low-temperature solution-deposition methods, fabricatingdonor-acceptor OSC blends and modules, as well as on a team of expert academic, National Llab and industrial collaborators offering unique modeling, fabrication, advanced ex-situ and in-situ characterization tehniques, organic thin-film processing, and techno-economic insights. This effort will encompass three shared interconnected research Tasks to achieve the goals of this project by achieving key focused deliverables. These are organized around the complementary specializations of the participating institutions to achieve maximum research efficiency and technology delivery.Task 1. Design and synthesize donor and acceptor polymeric semiconductors optimizing, simultaneously, blend mechanical deformation (ultimate strain, #u ) and PCE, initially in rigid OSCs. Deliverable 1: i. New polymer donor and molecular/polymer acceptors. ii. Deepunderstanding of the major factors optimizing mechanical deformation in pristine/blend OSC systems. iii. Achieve OSCs with #u > 60%and with PCE > 19%.Task 2. Engineer OSC blend and OSC long-term morphological stability in rigid and flexible OSCs. Deliverable 2: i. Photoactive and supporting materials for device mechanical and temporal stability. ii. Flexible cells with PCE > 18% (PCE retention >90%, 100.000 cycles @ radious = 1 cm). Stretchable cells with PCE >15% (PCE retention >90%, 10.000 cycles @ strain = 30%).Task 3. Fabricate mechanically agile OSCs and modules by printing for proof-of-concept applications. Deliverable 3. i. Printed flexible module with PCE > 12% (30#50 cm2, PCE retention >90%, 100.000 cycles @ radius = 1 cm, lifetime 10 years). Stretchable modules with PCE>10% (areas of 5#5 cm2, PCE retention >90%, 10.000 cycles @ strain = 30%, lifetimes of 5 years). ii. Integrate optimized flexible OSCs with other electronic, photonic, and sensor device technologies ideally those which would benefit from the target OSC mechanicalcharacteristics.To achieve maximum team collaborative effectiveness for this project will require close integration of the researchefforts of the two institutions. This will be achieved by biweekly zooms, exchange of samples and measurement data, indivual pedividual personnel exchange for transferring or exchanging experimental techniques and/or conducting experiments at a synchrotron or other specialized facility (e.g., NMR), and by an annual all-hands meeting, preferably co-located with aat a national conference or symposium.
