“…Graphdiyne with halogen functionalization has gained increasing attention for assisting in the optimization of morphological properties, conductivity, and bandgap of graphdiyne due to the various electronegativities and the size of halogen atoms . Chlorine‐substituted graphdiyne (ClGD), known as a derivated graphdiyne with abundant carbon and well‐defined features, is equipped with a 2D graphdiyne‐like carbon framework, comprising benzene rings (sp 2 carbon) and butadiyne linkages (sp carbon) . As reported in the literature, ClGD has a large pore size in the 2D molecule plane, providing a sufficiently wide anchor point for molecules on the plane direction.…”

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 (GD), first predicted in 1997, is a kind of new two‐dimensional carbon material. Recently, the large‐area GD film has been successfully synthesized on copper substrate via a cross‐coupling reaction by Li et al As a new allotropic form of carbon nanomaterials, GD, consisting of sp 2 ‐ and sp‐hybridized carbons, possesses highly π‐conjugated structure . Moreover, carbon networks of GD with delocalized π‐systems are of particular relevance owing to the tenability of their properties with ingenious changes in their electronic, optic, and geometric characteristics .…”

Graphdiyne-ZnO (GDZO) composite material is prepared via a simple method and studied in detail for the first time. The transmission electron microscopy, Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) analyses confirm the formation of an adduct between GD and ZnO. Then the interaction between ZnO and GD is further investigated by first-principles calculations. It is found that the Zn and O atom can coordinate bonding with GD, thus forming the C─Zn bond and C─O bond, respectively. Polymer solar cells are fabricated based on the nanocomposites for the first time and an enhanced power conversion efficiency of 11.2%, compared with the devices with ZnO-only (10%), is obtained. Simultaneously, the resultant devices show better stability, whether in glove box or in atmosphere, with humidity of 90%. The investigation of exciton generation rate, ideal current-voltage model, and impedance spectra verify that the introduction of GDZO not only accelerates electron transfer but also reduces charge recombination occurring at the interface. The results indicate that GDZO is a promising electron transport material to enhance solar cell performance and presents a large potential for optoelectronic applications as well.

“…Chen et al [23] and Luo et al [24] revealed the effect of graphyne allotropes stacking structure on the optical properties by density functional theory, which provided a theoretical basis for the structural identification of graphynebased photocatalyst. According to the results of many studies, the light absorption of GDY was related to its layer number and stacking arrangement.…”
