This work reports on the engineering and fabrication of transparent, conductive, flexible films made as a composite bacterial cellulose microfibers (BMF), polymer (either PVA or PEO), silver nanowires (AgNWs) viable cost-effective replacements to commercial indium-tin oxide (ITO) fluorine-doped tin (FTO) transparent conductors. The studies conducted indicate that optical mechanical properties B...

The improvement of the physical properties of Indium Tin Oxide (ITO) layers is quite advantageous in photovoltaic applications. In this study the ITO film is deposited by RF sputtering onto p-type crystalline silicon (c-Si) with (100) orientation, multicrystalline silicon (mc-Si), and glass substrates coated with ZnO and annealed in vacuum furnace at 400°C. Electrical, optical, structural a...

Single-walled carbon nanotubes (SWNTs), synthesized using the arc-discharge method and the direct-injection-pyrolytic synthesis (DIPS) method, were dispersed in a tetrahydrofuran solution containing propylamine and used to prepare transparent and conductive thin films on PET films using an airbrush technique. The SWNTs were analyzed using vis-near infrared absorption spectroscopy, Raman spectro...

A new single step direct-write photomask process has been proposed by using Bi/In bimetallic thermal resist which turns almost transparent with high energy laser exposure. The Bi over In metallic films, each layer ~40 nm thick, were DCsputtered onto quartz mask plate substrates in a single pump-down chamber. Before laser exposure the Bi/In had 2.91 Optical Density. Bi/In is a bimetallic thermal...

This work shows a simple, single-stage, scalable method for the continuous production of high-quality carbon nanotube-polymer transparent conductive films from carbon feedstock. Besides the ease of scalability, a particular advantage of this process is that the concentration of nanotubes in the films, and thus transparency and conductivity, can be adjusted by changing simple process parameters....

The fabrication of flexible transparent conducting films (TCFs) is important for the development of the next-generation flexible devices. In this study, we used double-walled carbon nanotubes (DWCNTs) as the starting material and described a fabrication method of flexible TCFs. We have determined in a quantitative way that the key factors are the length and the dispersion states of the DWCNTs a...

As we all know, transparent and conductive Al:ZnO (AZO) films are being considered for manufacturing transparent electrodes in flat panel displays, solar cells and organic light emitting diodes due to their high electro optical quality, high material availability and low material cost for large area applications. In this experiment, AZO thin films were prepared on glass substrate by Magnetron S...

Transparent conductive oxide (TCO) thin films are cornerstones in many optoelectronic applications including displays, photovoltaics and touchscreens. In these devices, with simultaneous high optical transparency electrical conductivity needed. Ideally, heat generated during normal device operation must ideally be compensated for to achieve optimum functionality. One possible way address the th...
