Summary: By developing a new trimer acceptor (TYT), this study achieves an organic solar cell (OSC) with high-performance (PCE > 18%) and stability (t(80%) lifetime > 8000 h). The trimerization approach results in the acceptor TYT with an upshifted energy level, leading to an efficient OSC with a high open-circuit voltage (0.964 V). Additionally, TYT has a higher glass-transition temperature (Tg) compared to monomer and dimer acceptors, effectively suppressing molecular diffusion and improving stability.

Summary: The characteristics of small molecules in all-small-molecule organic solar cells (ASM OSCs), such as well-defined chemical structure and excellent reproducibility between batches, have attracted great attention. However, balancing the aggregation behaviors of small molecules is a challenge, limiting the further development of ASM OSCs' efficiency. The asymmetric ending group strategy has been successfully employed in non-fullerene acceptors (NFAs). Inspired by this, two asymmetric and symmetric small molecule donors, Por-DPP-TR and PTR, were synthesized. The efficiency of ASM OSCs reached 16.31%, ranking as one of the highest PCEs.

Summary: In this study, a ternary system consisting of two small molecules (B2 and B3) as donors and a narrow bandgap non-fullerene small molecule acceptor Y6 was designed for organic solar cells. The presence of B2 in the B3:Y6 blend increased photon harvesting and formed cascade energy level structure, facilitating the charge transfer. Efficient energy transfer from B2 to B3 was observed, resulting in effective exciton utilization in the ternary device. The ternary device achieved an efficiency of approximately 12.88% with low energy loss, surpassing that of binary devices with B2:Y6 and B3:Y6 blends.

Summary: Tuning the properties of non-fullerene acceptors (NFAs) through halogenation is a promising strategy to enhance the performance of organic solar cells (OSCs). However, the influence of F and Cl choice on molecular packing and performance between small-molecule and polymeric acceptors remains unclear. This study investigates the effects of fluorination and chlorination on small-molecule and polymeric acceptors, and finds that chlorinated small-molecule acceptors exhibit better performance due to their stronger intermolecular packing mode, while fluorinated polymers achieve a denser packing mode and better performance compared to chlorinated polymers.

Summary: Currently, the use of benzo-dithiophene (BDT) units is dominating the development of high-efficiency organic photovoltaic devices. However, researchers have explored the use of benzo-difuran (BDF) units to diversify the choices of building blocks for donor polymers. In this study, a BDF-based polymer donor achieved the highest efficiency reported for BDF donor materials (18.4%) with the aid of a solid additive (2-chloronaphthalene), which showed significant effects in optimizing morphology and enhancing device parameters.

Summary: In this study, a vacuum-drying strategy in the two-step method was employed to fabricate low-lead perovskite solar cells with an impressive efficiency of 19.67%. The vacuum treatment induced the formation of low crystalline Pb0.3Sn0.7I2 films containing less solvent, thereby facilitating FAI penetration and suppressing pinholes. Compared to the conventional one-step method, the two-step fabricated low-lead perovskite films with vacuum-drying treatment exhibited larger grain size, lower trap density, weaker recombination loss, resulting in better thermal stability and a record-high efficiency near 20%.

Summary: This study investigates the thermodynamic and dynamic impact of additives with different pi-conjugation degrees on molecular packings in Y6-based OSC films using all-atom molecular dynamics simulations. The results demonstrate that the van der Waals interactions between the Y6 end groups and the studied additives are the strongest, and the pi-conjugation degree of the additive molecules determines the strength of the interactions with Y6 molecules. Strengthening the interactions between the Y6 end groups and the additive molecules not only accelerates the formation of ordered packing of Y6 molecules, but also reduces the intermolecular distances between Y6 molecules.

Summary: In this research, the phase transition behavior of cesium lead iodide (CsPbI3) quantum dot (QD) films under different temperature profiles was investigated using in situ scattering techniques. It was found that the phase transition from black phase to yellow phase can be induced by the instant heating-up (IHU) process, while the majority of QDs remained in the black phase under the slow heating-up (SHU) process. Further analysis revealed that the phase transition is triggered by the removal of surface ligands, which alters the energy landscape. The lattice symmetry plays a crucial role in determining the transition rate and the coexistence black-to-yellow phase ratio. Therefore, the lattice symmetry can be used as an indicator to monitor the phase transition of CsPbI3 QDs and adjust the coexistence ratio for specific applications.

Summary: The device performance of polymer solar cells (PSCs) is closely related to the microstructure of the active layer. Using a conjugated-block copolymer (CBC) as the active layer, we compared its photovoltaic performance with that of the bulk heterojunction (BHJ) system. Although both systems show high device efficiencies, the contributions of relevant photovoltaic parameters are different. Our work demonstrates that CBC materials are promising for reducing the efficiency-stability gap of PSCs, compared to BHJ systems.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
