We demonstrated an ITO-free, highly transparent organic solar cell with the potential to be integrated into window panes for energy harvesting purposes. A transparent, conductive ZnO/Ag/ZnO multilayer electrode and a Ag:Ca thin film electrode were used in this transparent device as the bottom and top electrode, respectively. To further improve the transmittance of the solar cell, the thickness ...

The increasing prevalence of three-dimensional (3D) printing optical housings and mounts necessitates a better understanding the properties materials. This paper describes method for using multithickness samples 3D materials to measure transmittance spectra at wavelengths from 400 2400 nm [visible short-wave infrared (IR)]. In this method, with material thicknesses 1, 2, 3, 4 mm were positioned...

Indium tin oxide (ITO) films have been deposited onto glass substrates by ifmagnetron sputtering without insitu substrate heating. The as-deposited films have an electrical resistivity of 5x1O a-cm, visible transmittance of about 85%, and infrared (IR) reflectance of above 80% at 5 jim. The effect of sputtering parameters on the deposition rate and the electrical and optical properties of ITO f...

SnO2 nanocrystalline thinfilms were prepared by spray pyrolysis method on glass substrates at 375, 400, 425, 450 and 500oC. Structural, optical and electrical properties of these films were studied by XRD, UVVisible and Four-probe methods. The change in electrical conductivity, band gap and optical transmittance was found to be a function of the change in lattice parameters ∆a and ∆c. The sampl...

The dielectric/metal/dielectric multilayer is suitable for a transparent electrode because of its high-optical and high-electrical properties; however, it is fabricated by an expensive and inefficient multistep vacuum process. We present a WO3/Ag/WO3 (WAW) multilayer transparent anode with solution-processed WO3 for polymer light-emitting diodes (PLEDs). This WAW multilayer not only has high tr...

We have used aqueous dispersions of silver nanowires to prepare thin, flexible, transparent, conducting films. The nanowires are of length and diameter close to 6.5 μm and 85 nm, respectively. At low thickness, the films consist of networks but appear to become bulk-like for mean film thicknesses above ∼160 nm. These films can be very transparent with optical transmittance reaching as high as 9...

This study evaluated the irradiance of curing units through core and veneered hot-pressed ceramics as well as the transmittance of these materials. Discs of 0.7, 1.4 and 2 mm in thickness of Empress (EMP) and Empress Esthetic (EST), and 0.8 (n=5) and 1.1 mm (n=5) thickness of Empress 2 (E2) were obtained. For E2, two of the 0.8-mm-thick discs were covered with dentin (1.2- and 1.4-mm-thick) and...

OBJECTIVES To evaluate the effect of Fe₂O₃on the optical properties of yttria-stabilised tetragonal zirconia (Y-TZP) dental ceramic when added, and to determine the correct content required to mimic the natural dentin. METHODS Disc-shaped Y-TZP specimens (0.50 ± 0.01 mm in thickness) containing various contents of Fe₂O₃were fabricated by cold isostatic pressing and pressureless sintering, and...

We report a comprehensive study of transparent and conductive silver nanowire (Ag NW) electrodes, including a scalable fabrication process, morphologies, and optical, mechanical adhesion, and flexibility properties, and various routes to improve the performance. We utilized a synthesis specifically designed for long and thin wires for improved performance in terms of sheet resistance and optica...
