“…The result shows that the ClGD‐PCBM film processes a faster electron extraction than pure PCBM, which qualifies ClGD‐PCBM as a good electron extraction layer for PSCs. Electrochemical impedance spectroscopy (EIS) was employed as an effective tool to analyze the charge transport and recombination processes of PSCs . Figure g shows the Nyquist plots of devices based on PCBM and ClGD‐PCBM.…”

Chlorine‐substituted graphdiyne (ClGD) is employed into electron transport layers (ETLs) of MAPbI3‐based perovskite solar cells for the first time, forming a high‐quality film with superior film morphology and electrical conductivity as compared with pristine [6,6]‐phenyl‐C61‐butyric acid methyl ester (PCBM) film. Strikingly, a champion power conversion efficiency of 20.34% is achieved, showing a 19% enhancement compared with the counterparts (17.08%). Simultaneously, ClGD‐PCBM‐based devices show suppressed J–V hysteresis. It is experimentally and theoretically demonstrated that the interactions of derivated graphdiyne and PCBM stem from four types of noncovalent bonds, which contribute to the improved device performance. The results suggest that derivated graphdiyne‐based interfacial material is promising for the applications in solar cells and other photoelectric devices.

“…Graphdiyne (GDY) is a two‐dimensional all‐carbon atomic crystal, which is widely investigated as an emerging material in many application fields. [ 22–26 ] The conductive network, porous structure, and mild preparation conditions make it possible to play such key role in coating the electrode. [ 27 ] According to Figure 1c, the structural comparison demonstrates that GDY may be a promising material to prevent the dissolution of the molecules in the electrochemical reaction, since the Li + accessible in‐plane cavities are significantly smaller than the organic molecules.…”

The preparation of organic small‐molecule cathodes is simple and low‐cost; however, their low conductivity and molecular dissolution are two key issues that mean their energy density and power performance are far lower than those of inorganic batteries, thus hindering their practical application. To develop an effective coating technology is the key to obtain high‐performance organic batteries. A general method of in situ weaving all‐carbon graphdiyne nanocoatings is demonstrated. The graphdiyne can be conformally weaved on organic particles under mild conditions so that the conductivity is increased and the dissolution is suppressed. After weaving graphdiyne nanocoat, the active mass of the small‐molecule organic cathodes rise to 93%, thus delivering a higher energy density of 310 W h kg−1 than previously reported, and the power performance and long‐term stability are greatly improved. Additionally, this method shows great potential to become the crucial technology for fabricating organic batteries with energy density close to prevailing lithium‐ion batteries.

View full text Add to dashboard Cite

Nanocarbon materials represent one of the hottest topics in physics, chemistry, and materials science. Preparation of nanocarbon materials by zeolite templates has been developing for more than 20 years. In recent years, novel structures and properties of zeolite-templated nanocarbons have been evolving and new applications are emerging in the realm of energy storage and conversion. Here, recent progress of zeolite-templated nanocarbons in advanced synthetic techniques, emerging properties, and novel applications is summarized: i) thanks to the diversity of zeolites, the structures of the corresponding nanocarbons are multitudinous; ii) by various synthetic techniques, novel properties of zeolite-templated nanocarbons can be achieved, such as hierarchical porosity, heteroatom doping, and nanoparticle loading capacity; iii) the applications of zeolite-templated nanocarbons are also evolving from traditional gas/vapor adsorption to advanced energy storage techniques including Li-ion batteries, Li-S batteries, fuel cells, metal-O 2 batteries, etc. Finally, a perspective is provided to forecast the future development of zeolite-templated nanocarbon materials.
