Summary: Understanding the molecular structure of non-fullerene acceptors (NFAs) and their impact on photostability is crucial for improving the stability of organic photovoltaic devices. This study reveals that end-group substitution on NFAs strongly modulates electron distribution within the molecule and affects intermolecular interactions, thus influencing photostability and morphological stability. The correlation between NFA quadrupole moment and photostability suggests a new synthetic direction for photostable organic photovoltaic materials.

Summary: The use of Non-Fullerene Acceptors (NFAs) has improved the conversion efficiency of organic solar cells (OSCs) to over 18%. However, OSCs still face stability issues under operational conditions. This study explored binary and ternary blends as active layers of OSCs, finding that using NFAs as a single electron-acceptor can greatly enhance stability while maintaining high efficiency.

Summary: In this study, six (two new) fullerene mono- and di-pyrene derivatives based on C-60 and C-70 fullerenes were successfully synthesized and characterized using spectral methods and cyclic voltammetry. The efficiency of solar cells made of these derivatives was analyzed, and it was found that the electronic and spectral properties of the derivatives, as well as the homogeneity of the photovoltaic layer, play a crucial role in determining the efficiency of the constructed solar cells.

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, 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: Perovskite-silicon tandem cells have higher efficiency than single-junction cells, reducing the cost of photovoltaics. Silicon subcells in tandem cells can last longer due to the protection provided by perovskites. This study demonstrates the recycling of silicon bottom cells from end-of-life tandem cells, maintaining their optoelectronic properties and comparable efficiency to fresh cells.

Summary: Three non-fullerene acceptors BTP-OC4, BTP-OC6, and BTP-OC8 with different 4-alkyloxyphenyl side-chains were synthesized via a new route without organotin reagent. The length of the alkyloxy group did not affect the energy levels and absorption of the acceptors, but it modulated the crystallinity and morphology of the active layer. The PM6:BTP-OC6 system showed the lowest energy loss of 0.513 eV, the highest power conversion efficiency of 17.59%, and excellent stability. Furthermore, when Y6 was introduced, the PCE increased to over 18%. Our study demonstrates a feasible strategy to develop high-performance acceptors by fine-tuning the aromatic side chain.

Summary: This study compares the photocurrent generation in dilute donor organic solar cells (DDOSCs) based on fullerene and non-fullerene acceptors. The results show that keeping the donor concentration low can avoid the formation of a percolation pathway for hole transport. The use of non-fullerene acceptors improves both charge generation and transport, with charge transport being more important in determining Jsc in DDOSCs.

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: This joint experimental and theoretical spectroscopy study aims to improve the understanding of the effect of photooxidation on the electronic structure of the fullerene derivative PC60BM. The researchers used X-ray Photoelectron Spectroscopy, Near-edge X-ray Absorption Fine Structure spectroscopy, and Fourier Transform Infrared Spectroscopy to analyze thin films of PC60BM before and after intentional exposure to simulated sunlight. The results of the study confirmed that photooxidation disrupted the conjugation of the fullerene cage and caused the formation of various oxidation products.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
