Kinetically templated fibrillar self-assembly via two-dimensional nanocrystals enables 21% efficient organic solar cells
The performance of organic solar cells (OSCs) is critically governed by the fibrillar organization of bulk-heterojunction active layers, yet controlling long-range, directional fibrillar morphology under nonequilibrium processing remains challenging. Here we report that two-dimensional cobalt phosphosulfide (CoPS3) nan...
