Abstract
Photoactive compounds are disclosed. The disclosed photoactive compounds include metal complexes with dipyrromethene-based ligands, which can be substituted with a variety of different side chains or groups or can include various fused ring configurations, such as including aromatic or heteroaromatic groups. The metal complexes may include two dipyrromethene-based ligands, which can be the same or different. The photoactive compounds can be used as photoactive materials in organic photovoltaic devices, such as visibly transparent or opaque photovoltaic devices.
