Abstract

The invention relates to a method for preparing a platinum electrode of the dye sensitized solar cell, belonging to the technical field of dye sensitized solar cells and comprising the following steps: 1) a glass substrate or a flexible substrate is soaked and cleaned in an ultrasonic cleaning machine; 2) heated and stirred in water bath, ethyl cellulose is slowly added into terpineol liquid according to the mass percentage to form an organic carrier; 3) analytically pure chloroplatinic acid is dissolved in the terpineol liquid in advance and then is added into the organic carrier and stirred evenly to prepare chloroplatinic acid slurry, the percentage of the chloroplatinic acid in the chloroplatinic acid slurry ranges from 0.1% to 1.0%; 4) a screen printing process is adopted and the prepared slurry is evenly coated on the clean conductive glass substrate or flexible substrate; and 5) after sintering, a uniform platinum electrode of large area is formed on the conductive glass substrate or flexible substrate. The method can improve the photoelectric conversion efficiency of the cell and the prepared cell has relatively good repeatability.

Description

technical field [0001] The invention belongs to the research field of dye-sensitized solar cells, and in particular relates to a method for preparing platinum electrodes of dye-sensitized solar cells. Background technique [0002] 1991 Ecole Polytechnique de Lausanne, Switzerland The professor applied nanotechnology to dye-sensitized solar cells and achieved remarkable results. Therefore, the research on dye-sensitized solar cells has also received extensive international attention and attention. [0003] Dye-sensitized solar cells are mainly composed of nanoporous semiconductor thin film photoanode, dye sensitizer, electrolyte and counter electrode. Since the counter electrode plays the role of transporting electrons and photocatalysis, the electron transport speed and photocatalytic effect of the electrode play an important role in improving the photoelectric conversion efficiency of the battery. [0004] At present, some counter electrodes of dye-sensitized solar cells...
