Mixed Molecular Orientations Help Charge Flow through Organic Solar Cells
Our newly published study shows that a mixture of face-on and edge-on molecular orientations can improve out-of-plane charge flow through the nanostructured donor-acceptor network in organic bulk heterojunction solar cells. This work was featured in the 2022 Chemical Communications Pioneering Investigators Issue.
