Although organic photovoltaic devices (OPVs) have been investigated for more than two decades, the power conversion efficiencies of OPVs are much lower than those of inorganic or perovskite solar cells. One effective approach to improve the efficiency of OPVs is to introduce additives to enhance light harvesting as well as charge transportation in the devices. Here, black phosphorus quantum dots (BPQDs) are introduced in OPVs as an additive. By adding 0.055 wt % BPQDs relative to the polymer donors in the OPVs, the device efficiencies can be dramatically improved for more than 10 %. The weight percentage is much lower than that of any other additive used in OPVs before, which is mainly due to the two-dimentional structure as well as the strong broadband light absorption and scattering of the BPQDs. This work paves a way for using two-dimentional quantum dots in OPVs as a cost-effective approach to enhance device efficiencies.

“…The most popular exfoliation method used to fabricate SAs is ultrasonication, in which ultrasound waves are employed to disrupt the weak inter-layer van der Waals forces within the 2D crystal ( Figure 1A, B). Ultrasonication has proved effective for most 2DM-based SAs, including graphene [36,41,[62][63][64][65][66][67]133], TIs [16, 59, 89, 91, 105, 107-111, 114, 136-138], TMDs [19, 39, 60, 74, 83-89, 91, 92, 96, 97, 99-104, 135, 139-142], and BP [42,[116][117][118][119][120][121][122][123][124][125][126][127][128][129][130][143][144][145]. Its popularity arises from the ease of use, low cost, and immediate availability across most laboratories [55,146,147].…”

AbstractSince graphene was first reported as a saturable absorber to achieve ultrafast pulses in fiber lasers, many other two-dimensional (2D) materials, such as topological insulators, transition metal dichalcogenides, black phosphorus, and MXenes, have been widely investigated in fiber lasers due to their broadband operation, ultrafast recovery time, and controllable modulation depth. Recently, solution-processing methods for the fabrication of 2D materials have attracted considerable interest due to their advantages of low cost, easy fabrication, and scalability. Here, we review the various solution-processed methods for the preparation of different 2D materials. Then, the applications and performance of solution-processing-based 2D materials in fiber lasers are discussed. Finally, a perspective of the solution-processed methods and 2D material-based saturable absorbers are presented.

Low‐dimensional (including two‐dimensional [2D], one‐dimensional [1D], and zero‐dimensional [0D]) semiconductor materials have great potential in electronic/optoelectronic applications due to their unique structure and characteristics. Many 2D (such as transition metal dichalcogenides and black phosphorus) and 1D (such as NWs) materials have demonstrated superior performance in field effect transistors, photodetectors (PDs), and some flexible devices. And in some hybrid structures of 0D materials and 1D or 2D materials, the modification of 1D and 2D devices by 0D materials is embodied. This type of hybrid heterostructure has a larger performance optimization compared with the original. In the application of PDs, the variety of low‐dimensional materials and properties enable wide‐spectrum detection from ultraviolet UV to infrared, which provide a potential option for PDs under various conditions. For flexible electronic devices, high performance and mechanical stability are two important features. Low‐dimensional materials offer unparalleled advantages in flexible devices. In this review, we will focus on the various low‐dimensional materials that have been extensively studied and their applications in the electronics/optoelectronic and flexible electronics. From the composition and lattice structure of materials (including alloys) to the construction of various devices and heterostructures, we will introduce their application and recent development under various conditions. These works can provide valuable guidance for the construction and application of more high‐performance and multifunctional devices.
