Dye-sensitized solar cells have better development prospects than silicon cells, and their main structural composition of nanoporous semiconductor films is particularly important. It is the tin dioxide film, and the effect of preparing tin oxide film on dye-sensitized solar cells under different conditions is studied. In this paper, the SnO2 powder was prepared by hydrothermal method, and the experiment was studied by controlled variable method. The properties of the obtained tin dioxide powder were characterized by SEM and three-dimensional ultra-depth microscope and XRD. The XRD diffraction peak is shown as tetragonal phase rutile type SnO2, With the increase of the concentration of tin tetrachloride solution, the coarser the particle size of the tin oxide crystal in the film, the more complicated the surface morphology, so that the specific surface area of the film is larger. At 0.1 mol/L, the surface of the film is a porous structure in the form of a loose sheet is presented. After analyzing the surface microstructure and flatness of the tin dioxide film, it can be concluded that the effect of salt concentration on the specific surface area of the film is extremely large. When the salt concentration is higher or lower, the obtained two the surface of the tin oxide film is relatively flat and has poor performance. When the salt concentration is 0.1mol/L, the surface of the obtained film has a large undulation and a large specific surface area, and the ability to adsorb the dye molecules can be predicted to be the greatest, and the photoelectric conversion efficiency is optimal in the photocatalytic process.

Thermal Oxidation Process

In this work, we studied the effect of rapid thermal oxidation process on the structural and surface morphology of silicon nanocrystal-based heterostructures. PLD technique was employed in combination with rapid thermal oxidation process to form multilayers heterostructures. Results show the dependence of the surface roughness and structure on the oxidation temperature. Best surface morphology was achieved at 723 K oxidation temperature, at which, the X-ray diffraction result ensured the formation of the Cu 2 O phase at (111) and (002) diffraction plain with uniform porous surface.

The effect of thermal oxidation temperature on the properties of MAO ceramic coating was investigated, The phase composition and surface morphology of composite oxidation coating were analyzed by XRD and SEM. The micro-hardness of composite oxidation coating were tested by micro hardness tester. The results shown that the composite oxidation coating consists of rutile, anatase Ti and HA. With the thermal oxidation temperature increasing, the micro-hardness of composite oxidation coatings were improved, but when the thermal oxidation temperature rose from 600 °C to 700 °C, the micro-hardness of coating dropped from 575 HV to 505 HV. With the thermal oxidation temperature increasing, the numbers of micro-porous on coating surface was decreased , and the composite oxidation coating became more density.
