Embodiment Construction

[0016] In the battery preparation process, diatomite powder and titanium dioxide powder are mixed according to a certain ratio, and a photoanode with excellent photoelectric performance is prepared on a conductive substrate. The counter electrode is made of conductive glass with high light transmittance, which can reduce the reflection of visible light and improve the utilization rate of sunlight.

[0017] The photoanode adopts the method of preparing diatomite-doped titanium dioxide film layer on the conductive substrate. The counter electrode is made of conductive glass with high light transmission function, and the counter electrode has the function of increasing the transmittance of visible light and reducing the reflection of visible light. The doping amount of diatomite in the photoanodic titanium dioxide coating is 5%-50%, and the coating thickness is 0.5-3μm.

[0018] Such as figure 1 The process flow is shown as:

Abstract

A method for producing a dye-sensitized solar cell is characterized in that: during the cell production process, diatomite powder and titanium dioxide powder are mixed according to a certain ratio, a photo anode is produced on an electric conduction basal body, and the photo anode adopts a diatomite doping titanium dioxide coating produced on the electric conduction basal body; and a counter electrode adopts high light transmission electric conduction glass, the doping amount of diatomite in the titanium dioxide coating of the photo anode is 5%-50%, and the thickness of the coating is 0.5-3mum. The novel dye-sensitized solar cell adopts diatomite doping titanium dioxide materials to produce the photo anode, the photoelectricity conversion efficiency of the dye-sensitized solar cell can be effectively improved, and the electron recombination is restricted. The novel dye-sensitized solar cell which is obtained through the method has the advantages of low production cost, high solar utilization rate, strong adaptability to environment and the like, and can simultaneously bear high solar radiation, so the efficiency of the cell is prevented from being reduced to influence the service life during the use.

Description

technical field [0001] The invention relates to the production field of inorganic non-metallic materials, in particular to the preparation of a high-performance photoelectric conversion functional material, that is, a preparation method of a dye-sensitized solar cell. Background technique [0002] Utilization of solar energy is one of the key research fields in the development and utilization of renewable green energy. Many countries have invested a lot of money in the research and development of solar photovoltaic cells. At present, photovoltaic cells made of monocrystalline silicon or polycrystalline silicon materials still occupy a major share of the market. However, due to the high cost of silicon materials, countries around the world generally adopt the method of providing subsidized electricity prices to promote the marketization of photovoltaic power generation. It can be said that high cost has become a huge obstacle restricting the further development of photovolta...
