Description
Technical Field
The invention belongs to the technical field of photovoltaic devices, and particularly relates to mesoporous titanium dioxide slurry and application thereof in preparing a printable mesoscopic perovskite solar cell electron transport layer at a low temperature.
Background
Perovskite solar cells have been rapidly developed in recent decades, and the energy conversion efficiency has been improved from 3.8% to 26.1% in the short decades, wherein printable mesoscopic perovskite solar cells have been paid attention to by many researchers due to their excellent stability, and the printable mesoscopic perovskite solar cells are sequentially conductive glass (FTO), dense titania layers, mesoporous zirconia layers and mesoporous carbon from top to bottom, wherein the mesoporous titania layers are used as electron transport layers, which are critical for the printable mesoscopic perovskite solar cells, however, the preparation process of the mesoporous titania layers requires high temperature sintering at least 500 ℃, the high temperature sintering process requires about 3 hours, and the time consuming preparation of mesoporous titania using the high temperature sintering method is extremely disadvantageous for commercial production.
Disclosure of Invention
In order to solve the technical problems, the invention provides mesoporous titanium dioxide slurry and application thereof in preparing a printable mesoscopic perovskite solar cell electron transport layer at low temperature.
In order to achieve the above purpose, the present invention provides the following technical solutions:
a mesoporous titanium dioxide slurry contains rutile phase titanium dioxide nano particles in raw materials. Because anatase titanium dioxide has a larger forbidden bandwidth, the anatase titanium dioxide is commonly used in the preparation of solar cells in the prior art, and the rutile titanium dioxide has good electronic conductivity, high transparency and good stability, so that the mesoporous titanium dioxide slurry is prepared by using rutile titanium dioxide nanoparticles.
Preferably, in the mesoporous titanium dioxide slurry, the particle size of the rutile phase titanium dioxide nano-particles is 20-30nm. The mesoporous channel narrow perovskite solution formed when the particle size of the rutile phase titanium dioxide nano-particles is smaller than 20nm is not easy to fill, and the reduction of the filling amount of the perovskite solution due to the reduction of the porosity of the titanium dioxide film formed when the particle size of the rutile phase titanium dioxide nano-particles is larger than 30nm can reduce the energy conversion efficiency of the device.
Preferably, the raw materials of the mesoporous titanium dioxide slurry further comprise a pore-forming agent and a solvent.
Preferably, the mass ratio of the rutile phase titanium dioxide nano-particles to the pore-forming agent is (6-8) to (1.5-1.8).
Preferably, the pore-forming agent comprises at least one of polyethylene glycol, polyacrylic acid, polystyrene, polyacrylonitrile and polymethyl methacrylate, and the pore-forming agents are low-temperature pore-forming agents; the pore formers can be removed at 300 ℃ to form a mesoporous structure, and the pore formers have the function of occupying space and can be removed in the final titanium dioxide film, so that the performance of the device is basically not influenced.
The solvent includes at least one of n-butanol, terpineol, ethylene glycol, and isopropanol.
Preferably, the raw material of the mesoporous titanium dioxide slurry further comprises a binder. The binder helps to improve the strength of the slurry after drying, and prevents cracking and collapse of the slurry during drying and calcination, thereby ensuring that the final sintered body has sufficient strength. The addition of a proper binder can ensure that the titanium dioxide film has enough strength and can ensure the integrity of the mesopores so as to ensure the filling of devices.
In the invention, when the pore-forming agent has the function of the binder, the pore-forming agent also plays the role of the binder; when the pore-forming agent does not have a binding effect, a binder is added. An optional binder is polyvinyl alcohol.

The invention preparesIn the process of the electron transport layer, the film is solidified at 80 ℃ and the pore-forming agent is removed at 300 ℃, so that the rutile phase titanium dioxide nano-particles can complete phase change without sintering at 500 ℃.
