Abstract

The invention discloses a method for preparing a titanium dioxide-zinc oxide nuclear shell structure nanometer fiber membrane, which is characterized in that: a light anodized membrane is a core part of a dye sensitized solar battery, physical and chemical decoration such as surface coverage is undertaken on the light anodic membrane, and development of a novel nanometer structure light anodic membrane is an important way for improving the property of the dye sensitized solar battery. A unique coaxial electrostatic spinning technique is adopted to prepare the titanium dioxide (TiO2) / zinc oxide (ZnO) nuclear shell structure nanometer membrane for a dye sensitized solar battery light anode. Due to the adoption of the technique, the formation of a standard quasi one-dimensional nanometer structure and the shell wrapping treatment for preventing the recombination of electric charges can be simultaneously realized. Crystal boundaries of the quasi one-dimensional nanometer structure is fewer, so the electronic recombination can be reduced, and short-circuit current Isc of the battery can be improved. By introducing a shell, an open-circuit voltage Voc of the battery can be increased. Correspondently, overall transformation efficiency Eta of the battery can be improved by 18 percent to 27 percent.

Description

technical field [0001] The invention relates to the technical field of solar cell manufacturing, in particular to a method for preparing a titanium dioxide-zinc oxide core-shell nanofiber film for a dye-sensitized cell. Background technique [0002] With the continuous development of society and economy, the depletion of non-renewable energy sources such as oil and coal, the survival and development of human beings are facing unprecedented challenges. Finding clean, renewable energy has become a global issue. It is estimated that the energy that the earth obtains from solar radiation every year is about 100,000 times the annual energy consumption of human beings. Therefore, the development and utilization of solar energy is a major issue in the field of new energy. Solar cells based on the pn junction principle of semiconductor silicon are currently the most mature photoelectric conversion devices. In recent years, the pace of large-scale application of silicon solar cells ...
