Two Different Squaraines: Insights into Efficiency - Chemistry Seminar

A Comparison of the Behavior of Two Different Squaraines: Insights into Efficiency

Daniel Saviola
Chemistry MS Candidate, RIT
Graduate Advisor: Dr. Christopher Collison


Squaraines (SQ) are a class of small organic molecules that show great promise for use in organic photovoltaics (OPV). In solid films, the SQ molecules are known to interact, readily aggregating together, which has a significant impact on their properties, thus effecting the overall efficiency of devices. In this work, the aggregation of two SQ is studied, and a model is created to spectroscopically determine the relative populations of aggregates compared to “monomers,” the primary goal being to determine a quantitative relationship between the degree of aggregation and device efficiency. Additionally, a new state of the SQ molecules is discovered, neither a monomer or a true aggregate, and its effect on efficiency is explored.
