Abstract
The new light-emitting organic materials used in OLEDs[1,2] belong to a type of charge injection, and our team has conducted a series of fluorescence studies. The dye-sensitized solar cell is currently the most discussed technology. The equipment that converts light energy into electrical energy is certainly worth studying. Our research on nano porous anodic aluminum oxide (AAO) nanomaterials is consistent with related research, in which titanium dioxide acts as an electron transport layer and AAO acts as a template. When the two are combined, their new properties are due to the higher mechanical strength of Al2O3 nanotubes and the electronic conductivity of TiO2 nanorods, which will increase the surface area of the DSSC anode to absorb dyes and enhance the anode The structural strength of the membrane. Finally, using different dyes, we noticed an increase in the efficiency of using AAO.
Highlights
Refer to most research[3] and data analysis, we using high purity aluminum as the base material, and by means of the use of nearly 0.4°C, 0.29M (2.69wt%) solution of oxalic acid to conduct anodization for the preparation of the periodic ordered, cellular shaped porous structure of the honeycomb alumina template, the effect of anodized phosphate reaming time and voltage on the diameter of the holes is discussed
Dyesensitized refers to the phenomenon of electronic excitation by light from the transfer of the dye molecules to the semiconductor conduction band, and returned by the surrounding electron oxidation state to provide supplementary dye process
Its battery works for the nano-porous structure adsorbed organic dye molecules, the use of an organic dye layer as the main light-absorbing layer, which absorbs light energy generated excitons, when electron-hole Coulomb interaction effects still need a low conduction band Lumo energy level of its semiconductor materials, as electron-hole separation medium, the electrons injected along a wide band gap semiconductor difference of the conduction band, and transfer to the semiconductor electrode via a conductive glass are collected via the outer loop export
Summary
Refer to most research[3] and data analysis, we using high purity aluminum (purity of 99%, 3.61 cm2 size) as the base material, and by means of the use of nearly 0.4°C, 0.29M (2.69wt%) solution of oxalic acid to conduct anodization for the preparation of the periodic ordered, cellular shaped porous structure of the honeycomb alumina template, the effect of anodized phosphate reaming time and voltage on the diameter of the holes is discussed. In the process of aluminum anodized becomes alumina film, with appropriate regulation of the concentration of 29% phosphoric acid reaming time, and with the voltage parameter, there will be re-adjustment of the alumina pore size and pore spacing, and the distance of pore structure and pore spacing will become large, resulting in forming different aspect ratio of the holes, in order to create a range of different nanoscale holes, called nanostructures holes template.
