Summary: In this study, 3D-structured molecules were introduced as guest acceptors to improve the photovoltaic performance of ternary organic solar cells (OSCs). Three four-arm molecules were successfully synthesized and added to the classical system, resulting in ultra-high power-conversion efficiencies. These molecules acted as energy donors to increase charge generation and also enhanced charge transfer between PM6 and the molecules. Introducing these molecules modified the molecular energy level and inhibited self-aggregation, reducing energy loss and balancing charge transport.

Summary: An organic solar cell using single-walled carbon nanotubes (SWCNTs) as the electron donor and fullerene derivatives as the acceptor is studied. Different combinations of SWCNTs and acceptors, including C-60 and three nonfullerene acceptors, are evaluated in bilayer solar cells. The results show that SWCNTs can extend the light absorption of the solar cells into the infrared region, but their concentration needs to be balanced with the solvent-induced changes to the active layer morphology.

Summary: Non-fullerene acceptors (NFAs) have significantly increased the efficiency of bulk heterojunction organic solar cells, with a potential milestone of 20% approaching. However, the mechanisms of how these materials function challenge the conventional understanding of organic solar cells. This study presents a Y6 device with an efficiency over 4.5% and investigates the generation, recombination, and transport of charges to understand the unique properties of Y6. The data suggests that Y6 generates abundant bulk free charges with ambipolar mobility that can be extracted when transport layers are present.

Summary: Ternary organic solar cells hold promise in enhancing power conversion efficiency through the combination of fullerene and non-fullerene acceptors for better charge dissociation and collection. The study on chalcogen-substituted PCBM derivatives revealed that the addition of PCBTh and PCBSe derivatives improved short circuit current density and fill factor, suppressing charge recombination. Surface and thermal analysis confirmed the importance of organized thin film nanomorphology in optimizing morphology and reducing carrier losses, with TOSC containing PCBTh exhibiting the highest power conversion efficiency at 14.6%.

Summary: Researchers have designed four new acceptors, Y6-NO2, Y6-IN, Y6-ERHD, and Y6-CAO, with different terminal groups. The results show that with the enhanced electron-withdrawing ability of the terminal group, the fundamental gaps become lower, the wavelengths of the main absorption peaks red-shift, and the total oscillator strength increases. Additionally, the electron mobility of Y6-NO2, Y6-IN, and Y6-CAO is significantly higher than that of Y6.

Summary: In this study, small molecule organic photovoltaics (SMPVs) were fabricated using a liquid crystalline donor material BTR-Cl and two similar optical bandgap non-fullerene acceptor materials BTP-BO-4F and Y6. The ternary SMPVs with 30 wt% Y6 achieved a high power conversion efficiency of 14.46% due to a well trade-off between phase separation and photon harvesting. Incorporating Y6 into the acceptors improved the performance of SMPVs significantly.
