“…In the early stage of research, small‐molecule‐based NIR photodiodes mainly adopted thermally evaporated PHJs due to the controllability of film morphology. The focus of research was mainly on phthalocyanine‐type small molecules, such as copper‐phthalocyanine (CuPc), lead phthalocyanine (PbPc), tin phthalocyanine (SnPc), neodymium phthalocyanine (NdPc 2 ), chloroaluminum phthalocyanine (ClAlPc), and indium (III) phthalocyanine chloride (ClInPc) . In 2011, Wang et al demonstrated an organic photodetector using CuPc as electron donor and a CuPc derivative, hexadecafluoro‐copper‐phthalocyanine complex (F16CuPc), as electron acceptor .…”

The inherent advantages of organic optoelectronic materials endow lightharvesting systems, including organic photovoltaics (OPVs) and organic photodiodes (OPDs), with multiple advantages, such as low-cost manufacturing, light weight, flexibility, and applicability to large-area fabrication, make them promising competitors with their inorganic counterparts. Among them, nearinfrared (NIR) organic optoelectronic materials occupy a special position and have become the subject of extensive research in both academia and industry.The introduction of NIR materials into OPVs extends the absorption spectrum range, thereby enhancing the photon-harvesting ability of the devices, due to which they have been widely used for the construction of semitransparent solar cells with single-junction or tandem architectures. NIR photodiodes have tremendous potential in industrial, military, and scientific applications, such as remote control of smart electronic devices, chemical/biological sensing, environmental monitoring, optical communication, and so forth. These practical and potential applications have stimulated the development of NIR photoelectric materials, which in turn has given impetus to innovation in light-harvesting systems. In this review, we summarize the common molecular design strategies of NIR photoelectric materials and enumerate their applications in OPVs and OPDs.

“…6b, the EQE exhibited the similar variation trend with d D , and a maximal EQE of 17% was obtained at d D =10 nm. This high value of EQE for NIR is larger than the OPDs based on the heterojunction composed of CuPc and copper hexadecafluorophthalocyanine (F 16 CuPc) [23] and of hydrazone end-capped symmetric squaraine and PCBM [24]. We suggest the increased EQE at the thinner NdPc 2 layers is originated from the photo-induced enhancement of electron tunneling from ITO electrode to C 60 layer across NdPc 2 layer.…”

Organic photodiodes (OPDs) have been the subject of extensive research due to their inherent advantages of largearea detection, wide range of material selection and low-cost fabrication. Near infrared (NIR) OPDs were realized mainly by using narrow energy-gap materials and doping organic NIR dyes into the active layer. Here we report on realization of NIR OPDs by exploiting the exciplex absorption in heterojunction consisting of neodymium phthalocyanine (NdPc2) and C60. For NIR OPDs based on NdPc2/C60 planar heterojunction with C60 thickness of 50 nm, the optimal NdPc2-layer thickness for specific detectivity is 30 nm, while that for photoresponsivity is smaller than 10 nm. A maximal specific detectivity of ~4.46×10 9 Jones was obtained at the optimized NdPc2 layer thickness of 30 nm. At NdPc2 layer thickness of 10 nm, a maximal photoresponsivity of 60 mA/W and a maximal external quantum efficiency (EQE) of 17% were obtained. The results presented here demonstrate that utilizing exciplex absorption in heterojunction based on NdPc2 and C60 is a prospective route for realizing NIR OPDs.
