Abstract ：
The construction of solar-to-chemical conversion system by mimicking the photosynthetic network of the chloroplast holds great promise on efficient solar energy utilization. We developed an artificial photosynthetic cell (APC) based on molecular biomimetic thylakoid (CoTPP-FePy) to split water into hydrogen and oxygen (H2 and O2) at low driving voltage (1.1 V) and neutral condition (pH approximate to 7). The CoTPP-FePy can emulate the light reaction in thylakoids to produce O2 by coupling light harvesting, photocatalysis, and electron/energy storage (FeIII/FeII-Py). Subsequently, a membrane electrode assembly (MEA) were employed to simulate the dark reaction, wherein the proton, electron and energy generated by the light reaction can drive the H2 producing process. By a temporally and spatially coupling of the light and dark reactions, the resulting APC achieved a solar conversion efficiency of 3.1 %, exceeding that of natural photosynthetic systems and demonstrating the potential of artificial photosynthesis.

Abstract ：
The solution-processible perovskite materials, utilizing the existing silicon infrastructure for perovskite/silicon tandem solar cells (P/S-TSCs), have attracted significant interest due to their low-cost and high efficiency. Hole-selective layers (HSLs) are essential for charge extraction and transport in P/S-TSCs. However, conventional HSLs often encounter issues such as poor conductivity, energy level mismatch, and incomplete coverage on textured surfaces. In this regard, a novel fully conjugated biscarboxylate-anchored self-assembled molecule with limited acidity, 5-(9H-dibenzo[a,c]carbazol-9-yl)-isophthalic acid (IPAPhCz), is developed to enhance interaction with the conductive oxide of ITO (Indium tin oxide), which forms a uniform and conformal coverage that significantly improves the crystalline quality of the top perovskite. Additionally, IPAPhCz features a large tilted dipole moment with optimized energy alignment for hole extraction. The resulting 1.68 eV single-junction PSC achieved a champion power conversion efficiency (PCE) of 22.78%, an increase of approximate to 10.37% over devices using 4PACz (PCE = 20.64%). Furthermore, textured P/S-TSCs based on IPAPhCz reached a champion PCE of 31.80% (approximate to 1 cm2), reflecting a approximate to 9.58% enhancement compared to that on 4PACz (PCE = 29.02%). Both devices incorporating IPAPhCz demonstrated improved stability. The findings present a significant methodology for the design of high-performance HSL materials for textured P/S-TSCs.

Abstract ：
The practical application of aqueous zinc-iodine (Zn-I2) batteries is hindered by poor iodine utilization and limited cycling stability, primarily due to the shuttle effect of soluble polyiodide species. In this study, side-group engineering is employed to modulate the electronic structure of hexagonal porous TpPa covalent organic frameworks (COFs). Among the engineered COFs, the nitro-functionalized TpPa COF (TpPa-NO2) outperforms in both I2 utilization and cycling stability, achieving a high specific capacity of approximate to 183 mAh g-1 at 0.1 A g-1 and a remarkable capacity retention of 84.3% after 10 000 cycles at 5 A g-1. Notably, the TpPa-NO2-based Zn-I2 batteries maintain mitigated polarization and stable operation under harsh conditions, including low temperatures (-5 degrees C) and high iodine loading (approximate to 15 mg cm-2). Theoretical simulations reveal that the electronic modulation reduces the TpPa COF's band gap and enhances the affinity for polyiodide species, thus improving the I2 utilization. These findings are further supported by in situ Raman and UV-vis spectroscopy, which identified a dominant I-/I5 - redox pathway and confirmed suppression of polyiodide dissolution. This work underscores the promise of electronically tailored COFs as advanced cathode hosts for long-life Zn-I2 batteries, offering an effective dual strategy to enhance iodine utilization and mitigate the shuttle effect.
