Abstract
The morphology features of polymer/small molecule/fullerene ternary organic solar cells are investigated. For the first time, simultaneously enhanced face-on molecular packing for both polymer and small-molecule donor materials is observed. This optimized morphology yields an enhanced performance at 40% small-molecule composition.
