Abstract

The invention discloses a method for improving the firmness of combination of a dye-sensitized cell nanometer fibrous membrane and conductive glass. The method comprises the following steps of: (1) spin coating a thin transition layer on the conductive glass before fiber deposition, wherein the thin transition layer is made of spin-coating liquid which has the same elements and higher viscosity compared with a TiO2 precursor spinning solution; (2) adding a proper amount of surfactant triton to the spin-coating liquid and the spinning solution; and (3) processing sintered TiO2 nanometer fibrous membrane with a TiCl4 aqueous solution. Under the synergic action of the three steps above, the firm combination of the TiO2 nanometer fibrous membrane prepared by an electrostatic spinning technology and an FTO (Fluorine-doped Tin Oxide) conductive glass substrate is realized, a key technical problem of application of the electrostatic spinning technology to preparation of a photoanode of a dye-sensitized solar cell is solved, and performances and stability of a deice are improved.

Description

technical field [0001] The invention relates to the technical field of solar cell manufacturing, in particular to a method for improving the bonding fastness of nanofiber membranes of dye-sensitized cells and conductive glass. 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...
