Optimizing side chains on different nitrogen aromatic rings achieving 17％ efficiency for organic photovoltaics
文献摘要：
Balancing charge generation and low energy loss (Eloss),especially in the wide spectral absorption region is critical to obtain high-performance organic photovoltaics (OPVs).Therefore,Y11-M and Y11-EB are designed and synthesized through modifying alkyl chains on different nitrogen aromatic rings of the reported non-fullerene acceptor Y11.Although all the molecules have almost similar low band-gap(around 1.30 eV),Y11-M and Y11-EB exhibit wider absorption in 410-870 nm region.Eventually,the conventional devices based on Y11-M and Y11-EB possess more efficient charge generation with low Eloss (around 0.44 eV),In addition,outstanding efficiencies of 16,64％ and 17,15％ with the fill factor of 76.15％ and 74.73％ are obtained in PM6:Y11-M and PM6:Y11-EB-based devices,both higher than Y11:PM6.The results highlight the importance of rational alkyl chains optimization,and a good structure-property relationship is established as well.
