Probing the bulk morphology of fullerene-free organic solar cell blends using SANS

DOI

The aim of this project is to develop an understanding of the relationships between the processing, nanoscale structure and device performance of bulk heterojunction, fullerene-free organic solar cells (OSCs). Optimised processing of OSCs has the potential to offer a low-cost, solution-processible, renewable energy source. We have fabricated fullerene-free OSCs based on a blend of ITIC, a small molecule non-fullerene acceptor and PBDB-T, a recently developed donor polymer, with efficiencies as high as 7.7%. We will build upon this work using SANS, to investigate the dependence of the properties of the phase separated nanoscale domains in non-fullerene photovoltaic blends, on processing factors such as thermal annealing, solvent annealing, casting solvent and blend ratio.
