1. Time-Resolved Electrostatic Force Microscopy of Polymer Solar Cells nm DMR-0449422 David Ginger, Dept. of Chemistry, University of Washington, Seattle, WA • Time-resolved electrostatic force microscopy allows direct mapping of variations • in local charging rates when donor/acceptor polymer blends are illuminated • These maps help us understand how these photovoltaic blends operate—identifying • regions of loss, and pointing to ways to improve efficiency Height Charging Rate Faster Slower arb. units D.
