Embodiment Construction

[0035] 1. Cleaning of conductive glass: Use distilled water, absolute ethanol, and acetone to ultrasonically clean the cut conductive glass for 30 minutes in sequence, and dry it for later use.

[0036]2. Platinum grid electrode: drip chloroplatinic acid solution with a syringe at 5 μl / s on the side of the cleaned FTO (100mm×120mm) conductive glass, put it in a muffle furnace and heat it at 400°C for 30min, take it out for use Anhydrous ethanol clear.

[0037] 3. TiO 2 Preparation of slurry: The slurry was mixed with P25, absolute ethanol, OP emulsifier, acetylacetone, and PEG2000 in a ratio of 20:1:1:4, stirred on a magnetic stirrer for 1 hour, and left to stand for 10 minutes for later use.

[0038] 4. Electrostatic spraying of TiO2 film: TiO2 2 The slurry is sucked into a 10ml syringe and installed on the syringe pump. Set the flow rate to 0.5ml / min. Turn on the CCD industrial camera and adjust the high-voltage DC stabilized current power supply. When the jet mode change...

Abstract

The invention provides a device and a method for rapidly manufacturing a large-area dye-sensitized solar cell and relates to optimization of a dye-sensitized solar cell manufacturing process in the field of new energy. One key problem to be solved in dye-sensitized cell research is as follows: industrial production and large-scale application are seriously restricted due to the fact that the photoelectric conversion efficiency and the cell stability are obviously different due to different manufacturing methods. The invention provides a method for manufacturing a dye-sensitized thin-film cell by utilizing a spray deposition method based on the electrostatic atomization principle, namely directly stacking, assembling and forming thin-film cell modules on various substrate materials by utilizing an electrostatic spraying technology and combining a method of automatically controlling simulated printing by a computer, and obtaining high-quality large-area dye-sensitized thin-film cell by virtue of optimizing related process parameters. The device and the method can be used for overcoming the defects of grid line breakage, short circuit, wavy reticulate patterns and the like caused by a process of manufacturing an electrode film by virtue of a silk screen printing method, and the defect of too compact and uneven magneto-controlled sputter coating.

Description

technical field [0001] The invention relates to a method for quickly preparing large-area dye-sensitized solar cells, in particular to an automatic spray-plating processing platform that combines electrostatic spraying technology and servo motor drive equipment, and uses it to rapidly prepare large-area dye-sensitized solar cells . Background technique [0002] Since 1991, the Gratzel research group of the Swiss Institute of Advanced Technology in Lausanne developed a nanocrystalline dye-sensitized solar cell, which broke through the photoelectric conversion efficiency of 7%. Dye-Sensitized Solar Cells (DSSC for short) has attracted the attention of scholars and experts from various countries, and its research has developed particularly rapidly in recent years. In 2011, the Gratzel research group increased the photoelectric conversion efficiency of solar cells to 12.3%. This performance is now comparable to that of silicon-based solar panels. However, due to the reasons of ...
