Summary: In most non-fullerene organic solar cells, the inter-domain connectivity of small-molecule acceptors is generally inferior to polymeric donors. By pre-depositing an ultra-thin acceptor primer layer and implementing sequential n-type doping, the connectivity of acceptor-phase is reinforced and the efficiency of the solar cells is greatly improved.

Summary: Organic solar cells with ternary bulk heterojunction active layers composed of small molecules provide a simple and efficient approach to enhance power conversion efficiencies. In this study, all-small-molecule ternary OSCs were constructed using a medium bandgap IDT-IC, a narrow bandgap F13, and a wide bandgap C1-CN. The crystalline nature of IDT-IC induced appropriate nanoscale in the C1-CN:F13 film, resulting in a higher PCE of 15.54% compared to C1-CN:F13 (14.23%) and C1-CN:IDT-IC (6.17%).

Summary: A novel structural design of oligomeric donor-acceptor (D-A) dyads has been established, showing advantageous optoelectronic, charge transport, and self-organization properties in single-material organic solar cells (SMOSCs). Post-treatment by solvent vapor annealing has also been investigated, revealing a lamellar supramolecular order of the dyads with a D-A phase separation smaller than 2 nm. The precise distance between donor and acceptor moieties ensures the fundamental physical processes operative in organic solar cells and provides stabilization of D-A interfaces.

Summary: Incorporating ITIC derivatives as guest acceptors into binary host systems is an effective strategy for constructing high-performance ternary organic solar cells (TOSCs). In this work, A-D-A type ITIC derivatives PTBTT-4F and PTBTP-4F were introduced into the PM6:BTP-BO-4F binary blend, and their impact on TOSC performance was investigated. Different device performances were observed, with PTBTT-4F ternary devices exhibiting an improved power conversion efficiency (PCE) of 17.67% and PTBTP-4F-based ternary devices yielding a relatively lower PCE of 16.34%.

Summary: The performance of nonfullerene-based organic solar cells is influenced by the morphology of the donor:acceptor blend, which is controlled by the composition. However, it is challenging to identify morphological design rules due to the complex relationship between composition-dependent phase behavior and device properties. In this study, the authors establish a direct link between PM6:Y6 film morphology and device properties by combining X-ray scattering and photocurrent spectroscopy. The results reveal that the charge transfer state at the amorphous-PM6:crystalline-Y6 interfaces controls the open-circuit voltage.

Summary: In this study, three non-fullerene acceptors (NFAs) with different end groups (F'-2Cl, F'-NCl, and F'-N2Cl) were designed and synthesized to investigate the impact of molecular structures and morphologies on the photovoltaic properties and energy loss of organic solar cells (OSCs). It was found that the PM6:F'-N2Cl based OSC exhibited a favorable morphology and achieved the highest power conversion efficiency (PCE) of 14.13% with a J(sc) of 20.31 mA cm(-2), a V-oc of 0.927 V, and a FF of 74.68%. Moreover, extending the conjugation of the end group led to a narrower molecular bandgap and lower energy loss in F'-NCl and F'-N2Cl based devices. This work provides an efficient strategy to optimize the molecular structures of non-fullerene acceptors and improve the properties of OSCs.

Summary: Non-fullerene acceptors have revolutionized indoor organic photovoltaics with high power conversion efficiencies, but transferring this performance to larger-scale prototyping remains challenging. The PM6:IO4Cl blend, a successful indoor OPV photoactive layer, is investigated for its industrial potential, and the thick and semitransparent devices are fabricated in air. Anomalous current-voltage characteristics are observed, with the cathode side generally outperforming the anode side due to a dead layer at the PAL/anode contact interface. Symmetric J-V curves and improved light utilization efficiency are achieved by making the PALs thin enough. Certain all-polymer and polymer:fullerene blends are identified as suitable candidates for thick device up-scaling, and ternary blends show potential in mitigating electrical asymmetry.

Summary: In this study, a detailed investigation of TMI mitigation by pump modulation based on multiple current waveforms in a fiber laser oscillator is carried out. Modulation of various waveforms increases the TMI threshold compared to continuous wave. The adjustment of phase difference between signal channels boosts the average output power of a stabilized beam. The TMI threshold is increased to 270 W under a modulation of pulse wave (duty cycle: 60%) with a phase difference of 440 μs, where the beam quality is 1.45. Adding groups of pump LDs and drivers further improves this threshold, providing a promising approach for beam stabilization of high-power fiber lasers.

Summary: Optimizing the molecular packing and orientation of dopant-free hole-transport materials (HTMs) is an effective strategy for achieving high-performance perovskite solar cells (PSCs). By regulating the donor building blocks and using a large core unit, we successfully demonstrated tunable molecular packing and orientation of polymers. The developed PC-DPP conjugated polymer with a preferred face-on orientation showed enlarged hole mobility and improved efficiency in PSCs compared to the control PBDT-DPP polymer with a preferred edge-on orientation. This work opens up possibilities for developing dopant-free HTMs.

Summary: In recent years, transverse mode instability (TMI) has been widely observed in fiber laser amplifier systems. However, the phenomenon of TMI in fiber laser oscillators has received less attention. This study focuses on the dynamical output properties of a 30-μm-core-diameter ytterbium (Yb)-doped fiber laser oscillator, including its temporal signal and modal characteristics. The TMI occurs at a pumping power of approximately 310 W. The study reveals complex interaction between the fiber laser oscillation and the TMI effect, calling for further understanding of TMI in fiber laser oscillators.

Summary: The current polymerization process of high-performance polymerized small molecular acceptors (PSMAs) through terminal groups of small molecular acceptors (SMAs) damages the preferred stackings of terminal groups and weakens the photoelectric performance of all-polymer solar cells (all-PSCs). To improve intermolecular stackings, a new pathway is explored by extending molecular conjugation in branched directions, resulting in two PSMAs of SP-T and SP-TT. The SP-T-based all-PSC exhibits a significantly improved efficiency of 13.54% compared to the SP-TT-based one with an efficiency of 9.76%, due to more compact/ordered stackings and superior morphology.

Summary: Perovskite light-emitting diodes (LEDs) have shown great potential for display and lighting applications with external quantum efficiencies exceeding 20% for various colors. However, the majority of internally generated photons are trapped in the devices and lose energy through lossy channels, suggesting the need for effective light management strategies. By analyzing the intrinsic optical properties of perovskite materials and the extrinsic properties related to device structures, this Review highlights the possibility of substantially exceeding the conventional limits of planar organic LED devices and suggests new approaches for achieving ultrahigh efficiencies in perovskite LEDs.
