“…Without considering the effect of energetic disorder, the value of E S1 – E CT is determined to be 0.14 eV for the PM6:Y6 (1:1.2), which means that a non-neglibigle driving force is still required for charge generation in PM6:Y6. In a recent report, a driving force around 0.16 eV was recognized to be optimal for the charge transfer rate in Y6-based BHJ cells . Therefore, we speculate the outstanding performance of PM6:Y6 cells is a result of this low but just right driving force.…”

For organic solar cells (OSCs), the charge generation mechanism and the recombination loss are heavily linked with charge transfer states (CTS). Measuring the energy of CTS (E CT) by the most widely used technique, however, has become challenging for the non-fullerene-based OSCs with a small driving force, resulting in difficulty in the understanding of OSC physics. Herein, we present a study of the PM6:Y6 bulk heterojunction. It is demonstrated that electro-absorption can not only reveal the dipolar nature of Y6 but also resolve the morphology-dependent absorption signal of CTS in the sub-bandgap region. The device with the optimum blending weight ratio shows an E CT of 1.27 eV, which is confirmed by independent measurements. Because of the charge transfer characteristics of Y6, the charge generation at PM6:Y6 interfaces occurs efficiently under a small but non-negligible driving force of 0.14 eV, and the total recombination loss is as low as 0.43 eV.

“…282 Convergent and biomimetic syntheses of penicimutanin A, penicimutanolone and penicimutatin established the absolute configurations as 788–790 respectively 283 and syntheses of peribysins A–C and F–G revised the stereochemistry of peribysins A, C, F and G (to 791–794 respectively) and represented the first syntheses of peribysins C, F and G. 284 Six step syntheses of the proposed and revised structures of (−)-versiquinazoline H led to correction of stereochemistry and the assignment of the absolute configuration as 795 . 285 Synthesis of (−)-curvulamine C has been achieved from commercially available starting materials 286 and its yield from the producing fungus has been improved through addition of precursors alanine and proline to the culture. 287 Known terrestrial flavone chrysin 796 was isolated from Chaetomium globosum as a new MNP.…”
