Optical properties of nanostructured TiO2 thin films and their application as antireflection coatings on infrared detectors.
Oblique-angle deposited titanium dioxide (TiO(2)) nanorods have attracted much attention as good antireflection (AR) coating material due to their low n profile. Therefore, it is necessary to better understand the optical properties of these nanorods. TiO(2) nanorods grown on glass and Si substrates were characterized in the visible (0.4-0.8 μm) and infrared (2-12 μm) regions to extract their c...
متن کاملThe influence of void space on antireflection coatings of silica nanoparticle self-assembled films
This study investigates the deposition by ionic self-assembly of alternating silica nanoparticle and poly allyamine hydrochloride layers with the goal to create a single-material antireflection coating. The condition that the optical thickness of the film be equal to /4 can be satisfied by depositing the requisite number of bilayers to obtain minimum reflectivity at the chosen wavelength. The s...
متن کاملTunable antireflection from conformal Al-doped ZnO films on nanofaceted Si templates
UNLABELLED Photon harvesting by reducing reflection loss is the basis of photovoltaic devices. Here, we show the efficacy of Al-doped ZnO (AZO) overlayer on ion beam-synthesized nanofaceted silicon for suppressing reflection loss. In particular, we demonstrate thickness-dependent tunable antireflection (AR) from conformally grown AZO layer, showing a systematic shift in the reflection minima fr...
متن کاملAmorphous Silicon Compound Films for Surface Passivation and Antireflection Coating of Crystalline Silicon Solar Cells
This chapter gives an overview of the theoretical bases of surface passivation and antireflection coating and describes the methods and equipment used to characterize the layers created in this work. While surface passivation is quantified by the effective surface recombination velocity Seff , this parameter cannot be measured directly. Instead, the lifetime measurements by QSSPC and ”PCD carri...
متن کاملNon-Vacuum Processed Polymer Composite Antireflection Coating Films for Silicon Solar Cells
A non-vacuum processing method for preparing polymer-based ZrO2/TiO2 multilayer structure antireflection coating (ARC) films for crystalline silicon solar cells by spin coating is introduced. Initially, ZrO2, TiO2 and surface deactivated-TiO2 (SD-TiO2) based films were examined separately and the effect of photocatalytic properties of TiO2 film on the reflectivity on silicon surface was investi...
