TL;DR: In this paper, the authors proposed a solution to eliminate the inconvenience caused by formation of a transparent electrode of metal oxide by eliminating the necessity to form the transparent electrodes of the metal oxide of ITO or the like requiring a high temperature annealing to give a harmful effect on an organic layer at a negative electrode in an organic EL element.
Abstract: PROBLEM TO BE SOLVED: To eliminate the inconvenience caused by formation of a transparent electrode of metal oxide by eliminating the necessity to form the transparent electrode of the metal oxide of ITO or the like requiring a high temperature annealing to give a harmful effect on an organic layer at a negative electrode in an organic EL element of a top emission type. SOLUTION: As for the organic EL element 10, a positive electrode 12, the organic layer 13 including the light-emitting layer 17, and the negative electrode 14 are consecutively laminated on the substrate 11, and light emission of the light-emitting layer 17 is taken out from the opposite side of the substrate 11. The negative electrode 14 is constituted of an electron injection layer 18 transparently formed by calcium of alkaline earth metal, and a covered layer 19 which covers the other side face of a face opposed to the organic layer 13 of the electron injection layer 18, and which is transparently formed by the metal (silver) to play a role to protect the electron injection layer 18. Then, this is formed so that resistance value of the negative electrode 14 becomes the resistance value or less of the transparent electrode made of the ITO (indium tin oxide) which is formed in the same shape as the negative electrode 14 and at the same position.

TL;DR: This review focuses on recent advances in surface-modified carbon nanotube networks for transparent conducting film applications and Fabrication methods will be described, and the stability of carbon Nanotube network films prepared by various methods will are demonstrated.
Abstract: The use of carbon nanotubes (CNTs) as transparent conducting films is one of the most promising aspects of CNT-based applications due to their high electrical conductivity, transparency, and flexibility. However, despite many efforts in this field, the conductivity of carbon nanotube network films at high transmittance is still not sufficient to replace the present electrodes, indium tin oxide (ITO), due to the contact resistances and semi-conducting nanotubes of the nanotube network films. Many studies have attempted to overcome such problems by the chemical doping and hybridization of conducting guest components by various methods, including acid treatment, deposition of metal nanoparticles, and the creation of a composite of conducting polymers. This review focuses on recent advances in surface-modified carbon nanotube networks for transparent conducting film applications. Fabrication methods will be described, and the stability of carbon nanotube network films prepared by various methods will be demonstrated.

TL;DR: In this article, a flexible and transparent indium tin oxide (ITO)/Ag/ITO electrode was fabricated on a polyethersulfone (PES) substrate using a specially designed roll-to-roll sputtering system at room temperature.
Abstract: We prepared a flexible and transparent indium tin oxide (ITO)/Ag/ITO electrode on a polyethersulfone (PES) substrate using a specially designed roll-to-roll sputtering system at room temperature for use in flexible organic solar cells (OSCs). By the continuous roll-to-roll sputtering of the ITO and Ag targets, we fabricated a flexible ITO/Ag/ITO electrode with a sheet resistance (Rsh) of 4.28 Ω/square, optical transmittance (T) of 89.28% and figure of merit value of 75.03 × 10−3 Ω−1 at the optimized Ag thickness of 12 nm (dc power of 200 W) without breaking the vacuum, even though it was deposited at room temperature. The bending test results demonstrated that the ITO/Ag/ITO electrode has superior flexibility to the single ITO electrode, due to the high failure strain of the ductile Ag layer. Moreover, the flexible OSC fabricated on the optimized flexible ITO/Ag/ITO electrode showed an identical efficiency of 3.73% to the OSC fabricated on the commercial crystalline ITO electrode, due to its low sheet resistance and high transparency, which are well matched with the organic active layer. This indicates that the flexible ITO/Ag/ITO multilayer electrode grown by the continuous roll-to-roll sputtering technique is a promising flexible and transparent electrode for use in cost-efficient flexible OSCs.

TL;DR: In this paper, the authors used asymmetric interdigitated electrodes to produce fluid flow of an ionic solution and achieved velocities in excess of 450μm/s at 2.2 V rms.
Abstract: Arrays of asymmetric interdigitated electrodes were used to produce fluid flow of an ionic solution. The electrodes were made of transparent (transmission ∼80%) indium tin oxide (ITO) and were powered by AC voltages of less than 5 V rms . We experimentally confirm predictions that the velocity of the fluid increases with the decreasing dimensions of the electrodes and we achieved velocities in excess of 450 μm/s at 2.2 V rms . Plug flow for the different electrode dimensions was obtained by placing one array at the bottom of a solution and the other at the top, leaving a gap of 280 μm. The experimental observations fit well with theory.
