manipulating the macroscopic and Microscopic Morphology of Large-Area Gravure-Printed ZnO Films for High-Performance Flexible Organic Solar Cells

Energy & Environmental materials 2024年第2期7卷 233-243页

Gravure printing is a promising large-scale fabrication method for flexible organic solar cells（FOSCs） because it is compatible with two-dimension patternable roll-to-roll fabrication. However, the unsuitable rheological property of Zn O nanoinks resulted in unevenness and looseness of the gravure-printed Zn O interfacial layer. Here we propose a strategy to manipulate the macroscopic and microscopic of the gravure-printed Zn O films through using mixed solvent and poly（vinylpyrrolidone）(PVP) *** regulation of drying speed effectively manipulates the droplets fusion and leveling process and eliminates the printing ribbing structure in the macroscopic morphology. The additive of PVP effectively regulates the rheological property and improves the microscopic compactness of the *** this method, large-area Zn O:PVP films（28 × 9 cm2） with excellent uniformity, compactness, conductivity, and bending durability were fabricated. The power conversion efficiencies of FOSCs with gravure-printed Ag NWs and Zn O:PVP films reached 14.34% and 17.07% for the 1 cm2PM6:Y6 and PM6:L8-BO flexible devices. The efficiency of 17.07% is the highest value to date for the 1 cm2FOSCs. The use of mixed solvent and PVP addition also significantly enlarged the printing window of Zn O ink, ensuring high-quality printed thin films with thicknesses varying from 30 to 100 nm.

MXene supported PtCo bimetallic catalyst for hydrogen evolution in acidic conditions

引用

Frontiers in Energy 2024年第3期18卷 369-377页

作者： Guangxun CHEN jian-hua ZHANG Kai-Ling ZHOU Yang YANG Haoxiang ma Yuhong JIN Jingbin LIU Hao WANG Faculty of materials and manufacturing Beijing University of TechnologyBeijing 100124China Institute of Deep-Sea Science and Engineering Chinese Academy of SciencesSanya 572000China

Using the electrochemical technology to split water molecules to produce hydrogen is the key to obtain green hydrogen for solving the energy crisis. The large-scale application of hydrogen evolution reaction (HER) in water dissociation requires a highly active catalyst. In this paper, the highly dispersed PtCo bimetallic nanoparticles loading on MXene (PtCo/MXene) were prepared by using a step-to-step reduction strategy. The mentioned PtCo/MXene catalyst exhibits a high current density of −100 ma/cm2 in an acidic medium with just a 152 mV overpotential. In addition, the PtCo/MXene catalyst also displays a superior stability. Computational analysis and experimental testing demonstrate that the electronic interaction between Pt and Co can effectively modify the electronic structure of the active site, thereby enhancing the inherent catalytic performance of the material. More importantly, MXene two-dimensional nanosheets can expose more active sites because of their large specific surface area. Furthermore, MXene substrate with excellent electrical conductivity and harmonious interfaces between PtCo and MXene enhance charge transfer efficiency and lower the reaction activation energy.
