Solar Cells: A Nonfullerene Small Molecule Acceptor with 3D Interlocking Geometry Enabling Efficient Organic Solar Cells (Adv. Mater. 1/2016)

In the past few years, fullerene-free organic solar cells have become the focus of many research efforts. On page 69, K. Cho and co-workers report a new non-fullerene small-molecule acceptor that has 3D interlocking geometry, enabling a nanoscale and bicontinuous 3D network morphology in bulk-heterojunction organic solar cells. This work provides important guidance to design the material structure and improve the performance of non-fullerene organic solar cells.
