Polymerization degree plays a vital role in material properties. Previous methodologies of molecular weight control generally cannot suppress or alleviate batch-to-batch variations in device performance, especially in polymer solar cells. Herein, we develop an in-situ photoluminescence system in tandem with a set of analysis and processing procedures to track and estimate the polymerization degree of organic photovoltaic materials. To support the development of this protocol, we introduce polymer acceptor PYT constructed by near-infrared Y-series small molecule acceptors via Stille polymerization, and shed light on the correlations between molecular weight, spectral parameters, and device efficiencies that enable the design of the optical setup and confirm its feasibility. The universality is verified in PYT derivatives with stereoregularity and fluoro-substitution as well as benzo[1,2-b:4,5-b’]dithiophene-based polymers. Overall, our result provides a tool to tailor suitable conjugated oligomers applied to polymer solar cells and other organic electronics for industrial scalability and desired cost reduction.

“…A PCE of 18.57 % and 19.54 % were achieved for PBTz-F : L8-BO and PBTz-F : PM6 : L8-BO based devices. Min et al synthesized two thieno[3,4c]pyrrole-4,6dione-based polymer donors PTTB-H and PTTB-F. [152] PTTB-F exhibited low energy level and stronger aggregation properties. The OSCs based on PTTB-F : L8-BO exhibited a higher PCE of 18.06 % than that of PTTB-H-based devices due to the reduced non-geminate recombination, improved charge transport, and optimized phase morphology.…”

The rapid development of narrow‐bandgap non‐fullerene acceptors (NFAs) has boosted the efficiency of organic solar cells over 19%. The new features of high‐performance NFAs, such as visible‐NIR light absorption, moderate HOMO, and high crystallinity, require polymer donors with matching physical properties. This emphasizes the importance of methods that can effectively tune the physical properties of polymers. Owning to very small atom size and strongest electronegativity, the fluorination has been proved the most efficient strategy to regulate the physical properties of polymer donors, including frontier energy level, absorption coefficient, dielectric constant, crystallinity and charge transport. Owing to the success of fluorination strategy, the vast majority of high‐performance polymer donors possess one or more fluorine atoms. In this review, the fluorination synthetic methods, the synthetic route of well‐known fluorinated building blocks, the fluorinated polymers which are categorized by the type of donor or acceptor units, and the relationships between the polymer structures, properties, and photovoltaic performances are comprehensively surveyed. We hope this review could provide the readers a deeper insight into fluorination strategy and lay a strong foundation for future innovation of fluorinated polymers.

In recent years, there has been a shift towards using nonfullerene electron acceptors in organic solar cells (OSCs) as a replacement for fullerene derivatives. This change requires polymer donors that possess compatible physical properties, such as absorption range, HOMO energy level, miscibility, and crystallinity. Moreover, the high cost and poor batch-to-batch reproducibility of polymer donors also hinder future large-scale manufacturing. These emphasize the need to explore alternative types of polymer donors. The imide-functionalized building units possess several key attributes that make their polymers highly promising for non-fullerene OSCs. These attributes include ease of synthesis, strong electron-withdrawing ability, rigid and co-planar structure, and the ability to easily tune solubility through imide side chains. In this review, we summarized the synthetic routes of imide building units, and the struc-tural evolution of imide-functionalized polymer donors by focusing on the effects of polymer structure on their physical, optoelec-tronic, and photovoltaic properties. We hope that this mini-review will serve as a catalyst for future research on imide-functionalized polymers toward high-performance, cost-effective, and durable organic solar cells (OSCs).
