“…Note that the signal intensity in STEM image increases with the atomic number producing chemically sensitive Z-contrast. The NW is in [1][2][3][4][5][6][7][8][9][10] zone axis showing multiple twinning. The corresponding electron diffraction pattern (EDP) being recorded in that axis and parallel to the wire growth axis, the latter was presently [1][2][3][4][5][6][7][8][9][10] (Figure 3 In order to understand the growth mechanism of Au NWs, let us discuss how the Au atoms from the evaporated Au thin film can diffuse and form an Au NW.…”

Due to their innocuity, Au nanowires present an interesting field of applications in biology and, particularly, in cancer therapy. Since their morphology and distribution can greatly affect their performances, being able to control their mode of growth is important. Various elaboration techniques including "top-down" and "bottom-up" approaches have been developed. In this work, we propose an efficient maskless method to grow Au nanowires with the help of hydrogen plasma treatment of Au thin films. We have been able to grow Au nanowires by taking advantage of spinodal dewetting of an Au thin film and the supply of silicon radicals resulting from hydrogen plasma etching of amorphous silicon coating the walls of the reactor. A variety of techniques have been applied to study the microstructure and the optical properties of Au nanowires. A strong photothermal effect of Au nanowires has been demonstrated with the help of visible laser light. In order to study the nanowire growth, the transport of Au atoms is discussed and a growth mechanism is proposed.

“…This included finding a printable alterative to ITO, avoiding vacuum and inert atmosphere processing steps, finding low-temperature methods, and developing printable electrode materials. [8][9][10][11][12][13][14] During this period the majority, if not all, of the reported high-performing active materials have been tested on a larger scale without increase in the PCE. This is seen as the scaling lag in Figure 1, where the PCE for industrially produced large-area devices is stagnant and does not increase over time.…”

The passage of time from laboratory demonstration of a technology-enabling efficiency value and until methodology and preparative means are in place is explored in this work for the polymer solar cell. Long technical strides need to be taken and efforts much beyond the laboratory solar cell need to be dedicated to bringing new solar cell material discoveries to service as an industrial technology. This includes scaled materials preparation, scaled manufacturing platforms, scaled installation platforms, as well as scaled electronics, monitoring, and control systems. We epitomize this as the ''scaling lag'' and highlight its importance when wishing to progress new solar cell materials from science to technology. The scaling gap is an observable element that can be extracted directly from experimental data and can be taken as a sign of technological maturity that can aid early-phase investors in their decision of when to invest in product development based on new technology.

“…Due to the low thickness of the active layer, nanostructured OPVs require precisely controlled fabrication process. Thus, most of the reported works about nanotextured designs have been focused on the transparent electrodes based on silver and copper nanowire arrays or theoretical studies on the architectural engineering of polymer solar cells, confirming the advantages of nanostructures in OPV devices . Furthermore, some groups fabricated OPVs with decent PCE on nanostructured transporting electrodes such as ZnO and ZnS nanowires and thus more systematic studies are required in this regard to enhance the light absorption in organic materials .…”

Low carrier mobility and lifetime in semiconductor polymers are some of the main challenges facing the field of organic photovoltaics (OPV) in the quest for efficient devices with high current density. Finding novel strategies such as device structure engineering is a key pathway toward addressing this issue. In this work, the light absorption and carrier collection of OPV devices are improved by employment of ZnO nanowire (NW) arrays with an optimum NW length (50 nm) and antireflection (AR) film with nanocone structure. The optical characterization results show that ZnO NW increases the transmittance of the electron transporting layer as well as the absorption of the polymer blend. Moreover, the as‐deposited polymer blend on the ZnO NW array shows better charge transfer as compared to the planar sample. By employing PC70BM:PV2000 as a promising air‐stable active‐layer, power conversion efficiencies of 9.8% and 10.1% are achieved for NW devices without and with an AR film, indicating 22.5% and 26.2% enhancement in PCE as compared to that of planar device. Moreover, it is shown that the AR film enhances the water‐repellent ability of the OPV device.
