Embodiment 1

[0029] A method for preparing a supported catalyst, comprising the steps of mixing 0.6 mmol of Co(NO 3 ) 2 ·6H 2 O was dissolved in 20ml of distilled water, 0.6mmol of Cr(NO 3 ) 3 ·9H 2 O was dissolved in 20ml of distilled water; Co(NO 3 ) 2 Solution, Cr(NO 3 ) 3 The solution was mixed with 16.7 mmol of carbon nanotubes, immersed in the dark for 12 h, dried at 60 °C after dipping, and calcined at 500 °C for 3 h under nitrogen protection after drying.

Embodiment 2

[0031] The difference from Example 1 is:

[0032] 0.4 mmol of Co(NO 3 ) 2 ·6H 2 O was dissolved in 20ml of distilled water, 0.6mmol of Cr(NO 3 ) 3 ·9H 2 O was dissolved in 20 ml of distilled water.

Embodiment 3

[0034] The difference from Example 1 is:

[0035] 0.6 mmol of Co(NO 3 ) 2 ·6H 2 O was dissolved in 20ml of distilled water, 0.4mmol of Cr(NO 3 ) 3 ·9H 2 O was dissolved in 20 ml of distilled water.

Abstract

The invention relates to a supported catalyst preparing method and application of a supported catalyst on an electrode on a dye-sensitized solar cell and belongs to the technical field of solar cells. The preparing method includes the following steps that metal salt I, metal salt II and a carbon source are steeped, dried and roasted in water according to the molar ratio of 1: (0.1-10): (10-100). The supported catalyst preparing method and application of the supported catalyst on the electrode on the dye-sensitized solar cell have the advantages that under same conditions, the photoelectric conversion efficiency is 9.26%, while the photoelectric conversion efficiency of Pt in the prior art on an electrode is 8.36%. Thus, the photoelectric conversion efficiency is improved by 1.11 times in comparison with the prior art.

Description

technical field [0001] The invention relates to a preparation method of a supported catalyst and its application on the counter electrode of a dye-sensitized solar cell, belonging to the technical field of solar cells. Background technique [0002] Under the general trend of the increasingly rapid development of society, the utilization of high-efficiency and environmentally friendly energy has become a topic that attracts much attention. Dye-sensitized solar cells have the characteristics of high theoretical conversion efficiency, simple fabrication process, abundant material sources, strong plasticity, no pollution and high transparency, which open up a new way for large-scale, low-cost and high-efficiency utilization of solar energy. Currently, the commonly used counter electrode of dye-sensitized solar cells is a conductive glass loaded with the noble metal platinum (Pt). However, the price of platinum counter electrodes is high, the reserves are very limited, and the r...
