Current characterization methods of the so-called Bulk Heterojunction
(BHJ), which is the main material of Organic Photovoltaic (OPV) solar
cells, are limited to the analysis of global fabrication parameters.
This reduces the efficiency of the BHJ design process, since it misses
critical information about the local performance bottlenecks in the
morphology of the material. In this paper, we propose a novel framework
that fills this gap through visual characterization and exploration of
local structure-performance correlations. We also propose a formula that
correlates the structural features with the performance bottlenecks.
Since research into BHJ materials is highly multidisciplinary, our
framework enables a visual feedback strategy that allows scientists to
build intuition about the best choices of fabrication parameters. We
evaluate the usefulness of our proposed system by obtaining new BHJ
characterizations. Furthermore, we show that our approach could
substantially reduce the turnaround time.
