Abstract

The invention discloses a preparation method of a transparent carbon electrode in a dye sensitization solar battery. According to the method, triton X-100 is used as carbon sources for preparing precursor solution, the precursor solution is coated on a conducting substrate in a suspended way at high speed, then, the conducting substrate is sintered for 0.5h in 500 DEG C argon gas protection atmosphere, and the required electrode is obtained. The method has the advantages that the cost is low, the operation is simple, the process is controllable, and the like. The transparent carbon electrode prepared under the optimum condition has high light transmission performance, high mechanical stability and considerable electrochemical catalysis performance, meanwhile, the defects of non-transparency and poor mechanical performance of the traditional carbon electrode are overcome, and the method can be used for preparing the front and back side light inlet transparent dye sensitization solar batteries, so the light utilization rate is improved, and the production cost of the batteries is further reduced.

Description

technical field [0001] The invention relates to a preparation method of a transparent carbon electrode in a dye-sensitized solar cell, belonging to the technical field of photovoltaic devices. Background technique [0002] Dye-sensitized solar cells are a new generation of solar cells developed by imitating the principle of photosynthesis. Compared with traditional solar cells, their main advantages are: low cost, relatively simple process technology, and good plasticity. It is non-toxic, non-polluting, and has broad application prospects. Dye-sensitized solar cells are usually composed of a titanium dioxide photoanode with dye attached, an electrolyte containing a redox couple, and a counter electrode loaded with metal platinum. The traditional platinum counter electrode is expensive and not suitable for large-scale production of cells. Therefore, it is cheap to develop And the non-platinum counter electrode with simple preparation process has become the only way for the i...

Problems solved by technology

[0004] So far, carbon electrodes are considered to be the most likely to replace platinum electrodes in the actual production of dye-sensitized solar cells. However, in order to obtain good catalytic performance, ordinary carbon electrodes usually need a certain thickness, about ten to dozens Micron, so it is difficult to achieve transparency, and the preparation process of many carbon electrodes for dye-sensitized solar cells reported so far, such as carbon nanotubes, graphene, porous carbon, etc., is complicated and the production cost is not low. Transparent carbon electrodes are also an important topic in the application field of dye-sensitized solar cells
