“…PCE improvements are reported by incorporating various metallic nanomaterials (i.e., Au and Ag NPs, nanosphere, nanodisk, and nanomesh) into interface layers of OPV devices such as PEDOT:PSS and MoO x for hole‐transport layers and TiO 2 and ZnO for electron transport layers. However, whether the dominant contributions to improved performance can be attributed to direct optical effects of the nanomaterials or other effects such as electrical or interfacial influence is still under debate.…”

Organic photovoltaic (OPV) devices, which can directly convert absorbed sunlight to electricity, are stacked thin films of tens to hundreds of nanometers. They have emerged as a promising candidate for affordable, clean, and renewable energy. In the past few years, a rapid increase has been seen in the power conversion efficiency of OPV devices toward 10% and above, through comprehensive optimizations via novel photoactive donor and acceptor materials, control of thin-film morphology on the nanoscale, device structure developments, and interfacial and optical engineering. The intrinsic problems of short exciton diffusion length and low carrier mobility in organic semiconductors creates a challenge for OPV designs for achieving optically thick and electrically thin device structures to achieve sufficient light absorption and efficient electron/hole extraction. Recent advances in the field of OPV devices are reviewed, with a focus on the progress in device architecture and optical engineering approaches that lead to improved electrical and optical characteristics in OPV devices. Successful strategies are highlighted for light wave distribution, modulation, and absorption promotion inside the active layer of OPV devices by incorporating periodic nanopatterns/nanostructures or incorporating metallic nanomaterials and nanostructures.

“…The metal film with hole array is reported to reduce the light reflection and achieve a balanced transmittance and conductivity . Pei and co‐workers demonstrated the formation of Au nanomesh with the closely packed polystyrene (PS) nanosphere . The Au nanomesh induced plasmonic effects has improved the short‐circuit current density ( J SC ) from 7.02 to 14.2 mA cm −2 .…”

Emerging novel metal electrodes not only serve as the collector of free charge carriers, but also function as light trapping designs in photovoltaics. As a potential alternative to commercial indium tin oxide, transparent electrodes composed of metal nanowire, metal mesh, and ultrathin metal film are intensively investigated and developed for achieving high optical transmittance and electrical conductivity. Moreover, light trapping designs via patterning of the back thick metal electrode into different nanostructures, which can deliver a considerable efficiency improvement of photovoltaic devices, contribute by the plasmon-enhanced light-mattering interactions. Therefore, here the recent works of metal-based transparent electrodes and patterned back electrodes in photovoltaics are reviewed, which may push the future development of this exciting field.

“…Some approaches use periodic patterns, e.g., anti‐reflection structures, periodic textures, 2D grating, and 3D grating and random structures, e.g., random microspheres, random wrinkles and in OSCs. Moreover, metal nanomaterials (e.g., nanoparticles (NPs), and nanoprisms, nanorods) have been incorporated into carrier‐transport layers and active layers for improving OSC performances. Very recently, multiple metal nanostructures and nanomaterials have been simultaneously introduced in OSCs to further enhance the light absorption, electrical properties, and performances of OSCs.…”

“…Various metal nanomaterials with different sizes, concentration have been introduced into hole‐transport layers such as poly(3,4‐ethylenedioythiophene):poly(styrenesulfonate) (PEDOT:PSS) and MoO x and more recently into electron‐transport layers such as TiO 2 for improving the power conversion efficiency (PCE) of OSCs. The improvements introduced by metal nanomaterials incorporated in OSCs are considered to be of different origins, such as plasmonic‐optical effect, high order resonances effect, scattering effects, plasmonic‐electrical (plasmoelectric) effect, charge‐storage effect and morphology as described below.…”

Two of the recent major research topics in optoelectronic devices are discussed: the development of new organic materials (both molecular and polymeric) for the active layer of organic optoelectronic devices (particularly organic light-emitting diodes (OLEDs)), and light management, including light extraction for OLEDs and light trapping for organic solar cells (OSCs). In the first section, recent developments of phosphorescent transition metal complexes for OLEDs in the past 3-4 years are reviewed. The discussion is focused on the development of metal complexes based on iridium, platinum, and a few other transition metals. In the second part, different light-management strategies in the design of OLEDs with improved light extraction, and of OSCs with improved light trapping is discussed.
