“…From the J−V curves we can see that the performances of the devices were decreased on the basis of GO/PEDOT:PSS devices (PCE = 5.90%) compared to the PEDOT:PSS ones, which is consistent with previously reported results. 37 The devices with Ag NPs/ PEDOT:PSS showed a higher PCE (7.11%) than the devices with PEDOT:PSS (6.58%), and the devices with GO−Ag NPs/ PEDOT:PSS showed the highest PCE (7.54%). These results indicated that the strong anchoring effect of Ag NPs on the GO surface and the synergistic effect of GO and Ag NPs on the GO−Ag NPs nanostructure are the key factors for enhancement effect.…”

A nanocomposite of silver-nanoparticle-decorated graphene oxide (GO-Ag NPs), enhanced by the surface plasmon resonance (SPR) effect, improved the performance of polymer solar cells (PSCs). The GO-Ag NPs were fabricated in situ via ultraviolet (UV) irradiation (254 nm) of GO and an aqueous solution of AgNO3. The photoexcited GO accelerated reduction of Ag(+) ions into silver nanoparticles (Ag NPs) upon UV irradiation, and the Ag NPs spontaneously deposited on the GO nanoflakes because the numerous functional groups on GO enable efficient adsorption of Ag(+) ions and Ag NPs via electrostatic interactions. The strong coupling between the SPR effect of GO-Ag NPs and incident light offers the probability of improved light absorption and corresponding exciton generation rate with enhanced charge collection, resulting in significant enhancement in short-circuit current density and power conversion efficiency (PCE). Therefore, the PCE of PSCs based on poly[4,8-bis(2-ethylhexylthiophene-5-yl)-benzo[1,2-b:4,5-b]dithiophene-2,6-diyl]-alt-[2-(2-ethylhexanoyl)thieno[3,4-b]thiophen-4,6-diyl] and [6,6]-phenyl C71-butyric acid methyl ester has been substantially elevated to 7.54% from 6.58% by introducing GO-Ag NPs at the indium tin oxide/poly(3,4-ethylenedioxythiophene):polystyrene sulfonic acid interface. In addition, the excellent properties of GO-Ag NPs, including its simple preparation, processability in aqueous solution, cost-effectiveness, and sustainability, make it suitable for the roll-to-roll manufacturing of PSCs.

Recent advances in the development of 2D-layered materials have witnessed the use of these materials as intriguing building blocks for various optoelectronic applications. The versatility of 2D material systems makes them particularly attractive for photodetection with fast response and high sensitivity over a broad spectral coverage, ranging from ultraviolet, visible to infrared. However, due to the atomically thin nature and inherent electronic structure, light that is harvested by monolayer 2D materials is extremely low and the photodetector devices often operate as Schottky junctions, which significantly limit the efficiency for photocurrent generation. Here, recent progress on the exploration of 2D material-based heterostructures and the engineering of the band structures for energy-efficient optoelectronic applications is reviewed. First, the strategies to introduce a bandgap in graphene are reviewed and discussed. This is followed by a discussion on the engineering of electronic structures in 2D transition metal dichalcogenides by localized chemical doping, dual gating, liquid gating, thickness modulation, and constructing heterojunctions. It is concluded by a summary and perspective on the challenges and future directions.

Continuous and scalable nanopatterning over flexible substrates is highly desirable for both commercial and scientific interests, but is difficult to realize with traditional photolithographic processes. The recent advancements in nanofabrication methodologies enable light management with photonic structures on flexible materials, providing an increasingly popular strategy to control the light harvesting in the optoelectronic devices of photovoltaics, and in organic and inorganic light-emitting diodes. Here, the current status of nanopatterning technologies for the fabrication of optoelectronic devices is summarized. Scalable nanopatterning technologies for nanomanufacturing on flexible materials are emphasized. Critical challenges in various patterning techniques when considering the resolution, scalability, processing throughput, and the use of masks and resists are addressed. The integration of flexible nanopatterned substrates with light manipulation in organic optoelectronic devices is also discussed; this enables the control of light flux and spectra. Finally, potential development directions are highlighted.
