The low-cost and easy large-scale fabrication advantages of printable mesoscopic perovskite solar cells(p-MPSCs)are overshadowed by their limited photovoltaic conversion efficiency(PCE).Here,we introduce the hydrazide derivative of 4-Hydroxybenzoylhydrazine(4-HBH)to improve the PCE of p-MPSCs by inducing enhanced defect *** carbonyl and hydrazine groups in hydrazide groups present strong interaction with *** hydroxyl group,as an electron donor group,increases the electron cloud density of the hydrazide group in 4-HBH under the conjugation of the benzene ring,and thus enhances its interaction with ***,the hydroxy group itself interacts with perovskite and passivates defects *** hydrazine agents can also reduce I2and suppress the loss of iodine in perovskite films,which inhibits the formation of iodine-related ***,p-MPSCs with 4-HBH achieve a high PCE of 19.21%,and present well improved stability.

The low-cost and scalable printable mesoporous perovskite solar cells(p-MPSCs) face significant challenges in regulating perovskite crystal growth due to their nanoscale mesoporous scaffold structure, which limits the improvement of device power conversion efficiency(PCE). In particular, the most commonly used solvents, N,N-dimethylformamide(DMF) and dimethyl sulfoxide(DMSO), have a single chemical interaction with the precursor components and high volatility, which is insufficient to self-regulate the perovskite crystallization process, leading to explosive nucleation and limited growth within mesoporous scaffolds. Here, we report a mixed solvent system composed of methylamine formaldehyde(MAFa)-based ionic liquid and acetonitrile(ACN) with the strong C=O–Pb coordination and N–H···I hydrogen bonding with perovskite components. We found that the mixed solvent system is beneficial for the precursor solution to homogeneously penetrate into the mesoporous scaffold,and the strong C=O–Pb coordination and N–H···I hydrogen bonding interaction can promote the oriented growth of perovskite crystals. This synergistic effect increased the PCE of the p-MPSCs from 17.50% to 19.21%, which is one of the highest records for p-MPSC in recent years. Additionally, the devices exhibit positive environmental stability, retaining over 90% of the original PCE after 1,200 h of aging under AM 1.5 illumination conditions at 55 °C and 55% humidity.

Objective: To report a case of beaver tail liver accidentally discovered by preoperative examination, and review relevant literature to improve the understanding of the anatomical variation of the liver. Methods: Analysis of a case of beaver tail liver incidentally discovered during preoperative examination for hepatic abscess in our hospital in June 2023. Combining domestic and foreign literature, the etiology, clinical manifestations, diagnosis, differential diagnosis, and treatment of beaver tail liver are discussed. Results: The patient was admitted due to abdominal pain and fever, with no other specific discomfort. An incidental finding of a beaver tail liver was discovered during imaging examinations. Conclusion: The beaver tail liver is a variant in hepatic anatomical morphology with nonspecific clinical manifestations. It is often incidentally discovered through imaging examinations such as ultrasound, CT, or MRI. Treatment is only necessary when the beaver tail liver is associated with hepatitis or tumors;otherwise, it does not require specific treatment.
