Abstract

Linear absorption measurements, current-voltage characteristics, and time-resolved microwave conductivity measurements were utilized to investigate the impact of molecular aggregation of a novel donor material on photovoltaic device efficiency. We report efficiencies of 2.4+/-0.3% and explain the increase in short-circuit current and efficiency as a function of the increased aggregation.
