Sequential Atmospheric Pressure Plasma-Assisted Laser Ablation of Photovoltaic Cover Glass for Improved Contour Accuracy
In this paper, we present sequential atmospheric pressure plasma-assisted laser ablation of photovoltaic cover glass. First, glass samples were plasma pre-treated using a hydrogenous plasma process gas in order to accomplish a modification of the near-surface glass network by a chemical reduction and the implantation of hydrogen. As a result, the transmission at a wavelength of 355 nm was reduc...
متن کاملPlasma-Assisted Deposition at Atmospheric Pressure
In plasma-assisted deposition methods the activation energy necessary for the initiation of chemical reactions is transferred via charged particles. Due to this fact in many cases the process temperature can be kept small, if gas discharges at pressures below 1 hPa are used. On the other hand low pressure requires a great deal of vacuum equipment. Processes at atmospheric pressure are more favo...
متن کاملModification of Glass Surface by Atmospheric Pressure Plasma
A Diffuse Coplanar Surface Barrier Discharge (DCSBS) operating in air at atmospheric pressure has been used to induce changes in the surface properties of glass. The contact angles of water drop on the surface of glass, which were measured by drop shape analysis, decreased markably with plasma treatment for 1 s. With the increasing of the plasma treatment time, the contact angles of the samples...
متن کاملLaser-assisted plasma coating at atmospheric pressure: production of yttria-stabilized zirconia thermal barriers
A laser-assisted plasma-coating technique at atmospheric pressure (LAPCAP) has been investigated. The electron temperature, electron density and gas temperature of the atmospheric-pressure plasma have been measured using optical emission spectroscopy (OES). LAPCAP utilizes laser ablation of 3 mol% yttria-stabilized zirconia into an atmospheric helium/nitrogen plasma to deposit thermal barrier c...
متن کاملInfrared laser ablation atmospheric pressure photoionization mass spectrometry.
In this paper we introduce laser ablation atmospheric pressure photoionization (LAAPPI), a novel atmospheric pressure ion source for mass spectrometry. In LAAPPI the analytes are ablated from water-rich solid samples or from aqueous solutions with an infrared (IR) laser running at 2.94 μm wavelength. Approximately 12 mm above the sample surface, the ablation plume is intercepted with an orthogo...
