In this paper, two-step sequential spin-dip and spin-spin coating, as well as one-step spin coating, methods are used to fabricate methylammonium lead mixed-halide perovskites to study the effect of process parameters, including the choice of the solvent, annealing temperature, spin velocity, and dipping time on the characteristics of the perovskite film. Our results show that using a mixture o...

Adhesion and homogeneity of the coating-substrate were analyzed on basis establishment coating mineralogy. Substrate raw materials used kaolin clay a calcined alumina 4 µm; series higher density ceramic coatings deposited using aluminas 0.5 µm µm, silica fume, talc. The dip technique was applied to all substrates later sintered at 1300 ºC. Shrinkage mixtures substrate separately evaluated. X-ra...

Rising temperatures significantly affect the PV module, decreasing its voltage and lowering output power. Furthermore, temperature rises have been linked to several module failures or degradation modes. The purpose of this study analyzes polyvinyl alcohol PVA on crystalline silicon solar cells as a thermal insulation thin film. films were prepared by dip-coating technique with thickness 1.15μm....

In this work we study the classical Landau–Levich problem of dip-coating. While in the clean interface case and in the limit of low capillary numbers it admits an asymptotic solution, its full study has not been conducted. With the help of an efficient numerical algorithm, based on a boundary-integral formulation and the appropriate set of interfacial and inflow boundary conditions, we first st...

Uniform nanostructure coating of TiO2 was prepared on 316L stainless steel by sol-gel method using Tetra-n-Butyle Titanat (TBT) as alkoxide material. 316L specimens were coated with the mentioned sol by dip coating method. The influences of preparation condition, pH of sol on TiO2 nanostructure coating were investigated. Their structural properties were examined at var...

In this work, Poly(ethyleneterephthalate) (PET) substrate was treated using KOH solution and was modified using hybrid O-I coating containing PCL )polycaprolactone( as organic phase and TEOS )tetraethoxysilane( as inorganic phase. The coating was prepared through a sol-gel process and applied on the surface by dip coater. Then, electrically conducting polythiophene (PTh) nanoparticles were depo...

The effect of titanium dioxide addition on bonding strength of CaO-P2O5 -Na 2O-TiO2glass-ceramic system was investigated as a coating on titanium substrate. Thus, different amounts of TiO2 (2, 3.5 and 5mol %) were added to the base glass batch composition. The prepared glaze slips were applied on the substrate by dip coating method, dried and then heat treated at various temperatures. After tha...

In a comparison between a bare diindenoperylene (DIP) film and a DIP film spin-coated with a layer of gold nanoparticles, we have investigated the influence of plasmon resonances in the gold particles on spectroscopic properties of the molecular film. Under off-resonant excitation with a laser at 633 nm, the bare DIP film showed only weak photoluminescence (PL) and Raman signals, but after spin...
