Summary: Rationally utilizing and developing synthetic units is crucial for designing high-performance non-fullerene small-molecule acceptors. In this study, four acceptors were developed based on a thieno[3,2-b]pyrrole synthetic unit, showing improved photovoltaic properties and energy utilization compared to the standard acceptor IT-4Cl. The ThPy3-based device achieved the highest PCE and excellent FF, while the ThPy4-based device achieved the lowest energy loss and smallest optical band gap.

Summary: Conjugated polymers, while being potential alternatives to inorganic semiconductors, face challenges such as complex synthesis, toxic byproducts, and lack of degradability or recyclability. A new synthetic approach using 1,4-dihydropyrrolo[3,2-b]pyrroles (DHPPs) as monomers has been developed, allowing for the targeted degradation of the resulting copolymers. The degradation is achieved through the dynamic equilibrium of azomethine bonds in the presence of acid. Monitoring of the degradation process using NMR, UV-vis absorbance, and fluorescence spectroscopies showed that the polymers were fully degradable.

Summary: Novel organic hole transport materials (HTMs), named T3, with high hole mobility, good band alignment and ease of fabrication, are designed and synthesized. The fluorine-substituted T3 (T3-F) exhibits the best band alignment and hole extraction properties, resulting in perovskite solar cells (PSCs) with outstanding power conversion efficiencies (PCEs) of 24.85% and 24.03% for aperture areas of 0.1 and 1 cm², respectively. The simple structure and tunable performance of T3 inspire further optimization for efficient PSCs.

Summary: Leveraging the self-assembling behavior of liquid crystals for controlling ion transport is of great significance. In this study, a liquid crystal material was designed and prepared, which showed ion-conducting behavior by adding an ion-conducting salt. The material maintained a well-ordered smectic phase within a certain concentration range. The study also found that forming irregular interfaces and expanding the film can enhance ion conduction.

Summary: Replacing pyrrole ring with pyrrolo[3,2-b]pyrrole in unidirectionally extended fused-ring electron acceptors significantly improves their performance. The designed nonfullerene acceptors 1PIC and 2PIC have red-shifted absorption peak, higher energy levels, and improved electron mobility. Photovoltaic devices based on the blend of PM6 donor and 2PIC acceptor achieve a higher power conversion efficiency due to more efficient exciton generation and dissociation, faster and more balanced carrier transport, and less charge recombination.

Summary: The new polymer P(BDT-fPPD) showed distinct properties compared to P(BDT-tPPD), with higher bandgap energy, deeper HOMO level, and higher crystallinity but lower carrier mobility and power conversion efficiency. The differences were attributed to the differences in backbone curvature between the two polymers, impacting their overall performance in organic solar cells.
