Hydrogen bonding and noncovalent interaction can make crystalline high efficiency polymer for polymer solar cell and exceeding over 9% PCE |
| 초록 |
The development of new semiconducting polymers for highly efficient polymer solar cells (PSCs) has been still challenging. This study reports highly efficient new polymer with a planar backbone formed via hydrogen bonding H---F, H---O, H---N and noncovalent coulomb interactions such as O---S, N---S and S---F interactions, leading to highly crystalline morphology in the film. The crystalline polymer has ideally balanced hole and electron mobility and optimized devices demonstrated efficiency of over 9% in a conventional single-cell device. On the other hand, in the absence of noncovalent interactions of same backbone, polymers showed twisted disorder amorphous nature, that makes lower and imbalanced hole-electron mobility with poor resulting device efficiency. We have realized that it is a good design strategy to consider hydrogen bonding and noncovolent interactions to increase the crystalline inter-chain orientation that’s highly beneficial for highly efficient PSCs materials. |
