Abstract

The invention belongs to the technical field of a nanometer material, and in particular discloses a method of preparing a conductive carbon fiber / platinum nanometer material and an application of the conductive carbon fiber / platinum nanometer material. The conductive carbon fiber nanometer material loaded with platinum nanometer particles can be obtained by dipping the conductive carbon fiber after being preheated in an ethanol or isopropanol solution of chloroplatinic acid for overnight and sintering. The conductive carbon fiber / platinum nanometer material obtained by the preparation method acts as the electrodes of a dye-sensitized solar battery pair; and by taking the conductive carbon fiber with good electrical conductivity and high flexibility as a substrate, the shortcoming that the performance of the battery is reduced because of the deformation and resistance of a conductive film is solved. The electrode can be applied to a solid light absorption type battery; the use ratio of sunlight is improved, so that the dye-sensitized solar battery can be used in a narrow space; the preparation method of the electrode is simple; the cost is low; and the preparation method is in favor of commercial application of the dye-sensitized solar battery in a large area.

Description

technical field

[0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a preparation method of conductive carbon fiber / platinum nanometer material and its application in dye-sensitized solar cells. Background technique

[0002] Since 1991, Professor M. Gratzel produced a dye-sensitized nanoporous TiO 2 Since dye-sensitized solar cells (DSSCs) with an energy conversion efficiency of 7.1%, dye-sensitized solar cells have become academic It is a hotspot of extensive research in the world and industry. At present, dye-sensitized solar cells are developing towards flexibility and solid-state, and three-dimensional light-absorbing cells have appeared to improve the utilization rate of sunlight.

[0003] Dye-sensitized solar cells are mainly composed of dye-sensitized semiconductor porous membrane working electrodes (the most commonly used is TiO 2 ), the electrolyte containing oxidation-reduction couples (such as I 3 - / I - )...
