Surface Coatings for Solar Application

Preparation and characterization of ZnO nanoparticles coated paper and its antibacterial activity study

“…[1][2][3][4][5][6][7][8][9] Thin films or nanoscale coating of ZnO nanoparticles on suitable substrates is also important for its potential applications as substrates for functional coatings, printing, UV inks, e-print, optical communications (securitypapers), protection, barriers, portable energy, sensors, photocatalytic wallpaper with antibacterial activity etc. 8,[10][11][12][14][15][16][17][18][19][20][21][22][23][24] Various methods like chemical, thermal, spin coating, spray pyrolysis, pulsed laser deposition etc. have been developed to coat ZnO nanoparticles in form of thin films on solid supports such as metal, metal oxides, glass or thermally stable substrates.…”

“…have been developed to coat ZnO nanoparticles in form of thin films on solid supports such as metal, metal oxides, glass or thermally stable substrates. [17][18][19][23][24][25][26] However, coatings of ZnO nanoparticles on thermolabile surfaces are scarce 27 and coating on paper is yet to be reported. Coatings with biomolecules, oil, pigments (calcium carbonate, clay, talc, silicates, TiO 2 , etc.…”

Effects of the Coating Process on Nanoscale Y2O3:Eu3+ Powders

“…Coated powders are used in many different areas. Nowadays, the coating process is an important technology in industry for the production of pigments having special optical properties or other physical properties. , Because of the large specific surface, the characteristics of nanoscale materials are apparently determined by the appearance structure. Many defects exist in the surface of nanoscale particles.…”

Global optimization of silicon photovoltaic cell front coatings

“…While single-layer front coating designs are well known, multiple layers could conceivably allow higher admittance over a broader bandwidth. Thus, the problem of optimizing multilayer coatings for solar cells has been a topic of great interest for some time [5][6][7][8][9][10][11][12][13][14], but the full range of possible designs had not been explored, especially for thin absorbers and/or multiple coatings. Here, we attack this problem with global optimization to find the best possible multilayer film designs in several regimes and quantify the degree of improvement which can be achieved in each case.…”
