ABSTRACTWe have developed a low cost and convenient approach to fabricate ITO-comparable transparent electrodes by using solution process of silver nanowires mixed with poly peroxotitanic acid (PPT) gel. The PPT gel is applied to connect the dispersed silver nanowires to preserve its high conductivity while remaining transparency and reducing surface roughness of the transparent electrode. The silver nanowires were synthesized via a modified polyol method, and the PPT gels were prepared by sol-gel method in appropriate concentrations. After applying the PPT gels, the sheet resistance of the transparent electrodes was improved from 192 Ω/□ to 44.7 Ω/□ with a transmittance of 81 %. And the roughness (RMS) was decreased from 106.3 nm to 48.1 nm. The PPT gel also improved the reliability of the proposed electrodes, which the conductivity was remained after general atmospheric storage of 6 months. We also demonstrate an Alq3 based OLED with the proposed transparent electrodes.

Electron Conduction

Thin-film transistors (TFTs) with zinc oxide channel layers were fabricated through a simple and low-cost solution process. Precursor solution concentration, annealing temperature, and the process were controlled for the purpose of improving the electrical properties of ZnO TFTs and analyzed in terms of microstructural scope. The fabricated ZnO films show preferential orientation of the (002) plane, which contributes to enhanced electron conduction and a dense surface. The results show that the TFT characteristics of the film are clearly affected by the microstructure. The optimized TFT operates in a depletion mode, shows n-type semiconductor behavior, and is highly transparent (>90%) within the visible light range. It exhibits a channel mobility of 9.4 cm2/V·s, a subthreshold slope of 3.3 V/decade, and an on-to-off current ratio greater than 105. In addition, the result of N2 annealing shows the possibility of improvement in electrical property of the ZnO TFTs.

Transparent Conductive Electrodes

AbstractOn the long road towards low-cost flexible hybrid electronics, integration and printable solar energy harvesting solutions, there is an urgent need for high-performance transparent conductive electrodes produced using manufacturing-ready techniques and equipment. In recent years, randomly-distributed metallic nanowire-based transparent mesh electrodes have proven highly-promising as they offer a superb compromise between high performances and low fabrication costs. Unfortunately, these high figure-of-merit transparent mesh electrodes usually rely heavily on extensive post-deposition processing. While conventional thermal annealing yields good performances, it is especially ill-suited for deposition on low-temperature substrates or for high-throughput manufacturing solutions. Similarly, laser-induced annealing severely limits the processing time for electrodes covering large surfaces. In this paper, we report the fabrication of ultra high-performance silver nanowires-based transparent conductive electrodes fabricated using optimized manufacturing-ready ultrafast photonic curing solutions. Using conventional indium tin oxide (ITO) as our benchmark for transparent electrodes, we demonstrate a 2.6–2.7 $$\times $$ × performance gain using two different figure-of-merit indicators. Based on these results, we believe this research provides an ideal manufacturing-ready approach for the large-scale and low-cost fabrication of ultra high-performance transparent electrodes for flexible hybrid electronics and solar-energy harvesting applications.

Aspect Ratios

Transparent conducting films based on solution-synthesized copper nanowires (Cu NWs) are considered to be an attractive alternative to indium tin oxide (ITO) due to the relative abundance of Cu and the low cost of solution-phase NW coating processes. Moreover, transparent electrodes tend to be flexible. This makes Cu NWs more attractive because ITO is brittle and can not meet the requirements of flexibility. For Cu NWs, aspect ratio is an important property. Cu NWs can be directly prepared by chemical reduction with various reducing agents and suitable capping agents. In general, the selectivity of the capping agent is very important for the formation of one-dimensional nanostructures because it plays a major role in the thermodynamic regulations and growth kinetics that influence the geometry and morphology of the crystal facets. Therefore, different aspect ratios are formed. Conductivity is the most important property for transparent electrodes. Organic pickling, annealing and glare pulses have a certain improvement in conductivity. Meanwhile, it is also essential to increase the oxidation resistance of the transparent electrode. The reduction of graphene oxide (r-GO), the coating of metal and polymer improve the oxidation resistance of the transparent electrode to varying degrees. This paper reviews the effect of different capping agents on the aspect ratio of NWs, and the effects of different post-treatments on oxidation resistance and conductivity of transparent electrodes.
