“…The expansion of the heterogeneous interface is conducive to the separation of photogenerated e-h pairs, resulting in greater photocurrent. A core–shell heterostructure is a typical structure with a large heterogeneous interface that is widely used in the field of photoelectric detection [ 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 ].…”

Self-powered ultraviolet (UV) photodetectors have attracted considerable attention in recent years because of their vast applications in the military and civil fields. Among them, self-powered UV photodetectors based on p-n heterojunction low-dimensional nanostructures are a very attractive research field due to combining the advantages of low-dimensional semiconductor nanostructures (such as large specific surface area, excellent carrier transmission channel, and larger photoconductive gain) with the feature of working independently without an external power source. In this review, a selection of recent developments focused on improving the performance of self-powered UV photodetectors based on p-n heterojunction low-dimensional nanostructures from different aspects are summarized. It is expected that more novel, dexterous, and intelligent photodetectors will be developed as soon as possible on the basis of these works.

“…Liu and Yang developed a new in situ electrochemical method for preparing GDY-1/CuS core-shell semiconductor heterojunction nanowires. [81] The nanowire could act as a diode; the rectification ratio depended on the area of the junction, with the highest value of 238.08 at a bias of 0.5 V achieved for a junction area of 0.0162 m 2 . Increased junction areas gave smaller rectification rates.…”

Graphdiyne (GDY), a two-dimensional allotrope of graphene, was first synthesized in 2010 and has attracted attention as a new low-dimensional carbon material. This work surveys the literature on GDYs. The history of GDYs is summarized, including their relationship with two-dimensional graphyne carbons and yearly publication trends. GDY is a molecule-based nanosheet woven from a molecular monomer, hexaethynylbenzene; thus, it is synthesized by bottom-up approaches, which allow rich variation via monomer design. The GDY family and the synthetic procedures are also described. Highly developed -conjugated electronic structures are common important features in GDY and graphene; however, the coexistence of sp and sp 2 carbons differentiates GDY from graphene. This difference gives rise to unique physical properties, such as high conductivity and large carrier mobility. Next, the theoretical and experimental studies of these properties are described in detail. A wide variety of applications have been proposed for GDYs, including electrocatalysts and energy devices, which exploit the carbon-rich nature, porous framework, and expanded -electron system of these compounds. Finally, potential uses are discussed.

“…In this study, we employed graphdiyne (GDY), a 2D planar carbon allotrope (formed by connecting two adjacent benzene rings (sp 2 ) with a diacetylenic linkage (sp) in the graphyne structure [22][23][24][25][26][27][28][29][30] ), as interface linker for the perovskite ((FAPbI 3 ) 1 − x (MAPbBr 3-y Cl y ) x ) and the HTL (Spiro-OMeTAD). We found that the GDY can efficiently reduce defects by suppressing the formation of metallic Pb on the surface of the perovskite film, and meanwhile form strong π-π interaction with Spiro-OMeTAD.…”

Interface engineering has been proven a powerful tool to improve performances of the perovskite solar cells (PSCs). Herein, highly π-conjugated graphdiyne (GDY) is employed as an interface linker between the perovskite film and the hole transport layer (HTL). It is found that GDY can significantly suppress the formation of metallic Pb (a detrimental defect), and reduces carrier recombination. The linker can also form π-π stacking interaction with the HTL, and facilitates transport and collection of photogenerated holes. The perovskite/GDY/HTL combination leads to large improvement in both power conversion efficiency (from 19.94% to 22.17%) and device stability. In addition, the GDY is also applied to the 3D/2D PSCs, and an outstanding PCE of 23.42% is achieved.
