The performance of polythiophene based polymers as a donor in donor:acceptor organic photovoltaic devices is highly dependent on its chemical architecture, molecular conformation, and nanoscale morphology, as the optical and electronic properties are highly structurally sensitive. Here we use classical methods to sample structure and mixed quantum-classical methods to analyze photophysical properties and excited state dynamics. Insight is gained into the role of regioregularity, side chains, and aggregation in the morphology and spectroscopic properties from single polymer chains, to nanosized aggregates and bulk films.
