Problems solved by technology

[0005] When Korean Kang et al. solved this problem, they first deposited a thin layer of insulating layer on the stainless steel substrate, and then deposited a layer of transparent conductive oxide. Although they obtained better performance, this increased the production cost of the battery. , and did not take advantage of the better electrical conductivity of the stainless steel substrate
Taiwan's Chih-Ming Chen et al. adopted low

Abstract

The invention discloses a method for preparing a dye sensitized solar cell with a stainless steel substrate, which includes the following steps: (1) placing the stainless steel substrate in pickle liquor for pickling treatment, (2) placing the stainless steel substrate after pickling in passivation solution for passivation treatment, (3) plating platinum on the surface of the passivated stainless steel substrate, and (4) assembling the platinum-plated stainless steel substrate serving as a counter electrode, an photoanode and electrolyte together to form the dye sensitized solar cell. By means of the method, the stainless steel substrate is performed with pickling and passivation treatment, the counter electrode used as the dye sensitized solar cell is sintered and plated with platinum at high temperature, a layer of stable oxidation film is formed on the stainless steel surface after passivation, and the layer of stable oxidation film effectively relieves oxidation corrosion on the stainless steel substrate during high-temperature platinum plating. Simultaneously, the layer of stable oxidation film prevents iodine-containing electrolyte from corroding the stainless steel substrate after the battery is formed through packaging, further pollution on the electrolyte caused by corrosion products is reduced, and long-period stability of the dye sensitized solar cell with the stainless steel substrate is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a method for manufacturing a dye-sensitized solar cell with a stainless steel substrate. Background technique [0002] The low production cost and simple preparation process make dye-sensitized solar cells (DSSCs) have attracted widespread attention since their inception. A dye-sensitized solar cell usually consists of a working electrode (usually a dye-sensitized semiconductor oxide film gathered on a glass plate with a transparent conductive film), an electrolyte (containing a redox pair, usually an I3- / I- pair) and a pair Electrodes (usually platinum electrodes), the biggest difference from traditional solar cells is that the absorption of light and the transmission of photogenerated carriers are completed by different substances. [0003] The substrate is one of the essential components for the normal operation of dye-sensitized cells. The general requiremen...
