Shuttlecock Fullerene Solar Cells
We utilize self-assembly to deterministically control nanoscale morphology in polymer-fullerene bulk-heterojunction (BHJ) solar cells
Self-assembly is a powerful methodology in controlling nanoscale morphology. Our collaborators in the Rubin group have designed a large array of penta-adduct fullerenes, termed shuttlecocks due to their propensity to stack into one-dimensional columnar arrays. Altering the size of the shuttlecock substituent allows a wide variety of shuttlecock assembly motifs to be accessed. Atomic force microscopy, x-ray diffraction and fluorescence quenching studies, are employed to determine how the shuttlecock assembly can potentially alter and direct the nanoscale morphology within the BHJ solar cell. Due to the large array of device morphologies that can then be accessed the relationship between morphology and device performance can also be readily examined.
