We will discuss the synthesis and characterization of a range of organic photovoltaic (OPV) active-layer materials prepared and studied in our laboratories during the past 12 months. These materials incorporate robust, redox-tunable perfluoroalkylfullerenes in donor/acceptor block copolymers (as self-assembled molecular heterojunctions) as well as encapsulated one-dimensional acceptor arrays within the helical cavity of macromolecular donor assemblies and stereocomplexed donor-polymer/acceptor polymer blends (as patterned bulk heterojunctions) with tunable morphologies and energetics. We will also discuss correlations between photocarrier dynamics and energetics and the morphological characteristics of the new OPV materials and our efforts to use these correlations to fine-tune the properties of the materials to intentionally enhance OPV device performance.
