Oligomeric Acceptor Enables High-Performance and Robust All-Polymer Solar Cells with 17.4% Efficiency

Zhixiang Li et al.

Summary: Researchers reported a new polymer acceptor, PZC24, which achieved a high power conversion efficiency of 16.82% when blended with PM6. To further enhance the performance, they designed and synthesized an oligomeric acceptor, CH-D1, as a third component for the all-PSC system. The ternary devices based on PM6:PZC24:CH-D1 exhibited an impressive efficiency of 17.40% and improved stability compared to the binary system. This strategy also showed universality in other all-PSC systems with PCEs over 17%.

Dimerized small-molecule acceptors enable efficient and stable organic solar cells

Cheng Sun et al.

Summary: In this study, it is demonstrated that the dimerization of a small-molecule acceptor (SMA) significantly enhances the stability of SMA-based organic solar cells (OSC). The dimerized SMA (DYBO) leads to high-efficiency OSCs (> 18% PCE), outperforming OSCs based on their monomer counterpart MYBO (PCE = 17.1%). DYBO-based OSCs show excellent thermal and photo stability, retaining over 80% of initial PCE after 6,000 hours of thermal exposure at 100 degrees C, while MYBO-based OSCs degrade to -80% of their initial PCE value in 36 hours. The high stability of DYBO-based OSCs is mainly attributed to its high glass transition temperature (Tg) of 179 degrees C (Tg of MYBO = 80 degrees C) and improved blend miscibility that stabilizes the blend morphology under thermal stress.
