Description
Technical field
The present invention relates to technical field of solar batteries more particularly to a kind of solar battery compacted zone slurry and its systems
Preparation Method.
Background technique
Currently, solar battery is widely used because of its environmentally protective characteristic with the application of heliotechnics.Dye
Expect sensitization solar battery and perovskite solar energy energy battery since its manufacture craft is simple, production cost is low, environmental-friendly, light
Photoelectric transformation efficiency is high, the advantages that having a wide range of application has obtained domestic and international extensive and in-depth research.Wherein, it is manufactured in actual processing
In the process, a key factor for restricting dye-sensitized solar cells and the promotion of perovskite solar battery efficiency is photoproduction electricity
The reverse transmission of the reverse transmission of the compound and light induced electron of son, light induced electron makes battery generate backward current, backward current
It is exported in the presence of the electric current for greatly reducing battery.It can but introduce compacted zone between conductive substrates and mesoporous titanium dioxide layer
Effective anti-conductive substrates are directly contacted with electrolyte or perovskite material, are avoided the generation of backward current, are strengthened simultaneously
The connection of TiO 2 porous layer and substrate is conducive to the raising of incident photon-to-electron conversion efficiency.Compacted zone in the prior art is usually adopted
With titanium dioxide dense film, and the preparation of titanium dioxide dense film is all based on the side such as spin-coating method, czochralski method, infusion process
Method, these methods are complicated for operation, technology stability is poor, discontinuous, are not suitable for preparation and the production line of large-area compact film
Continuous productive process, be unfavorable for the industrialization of dye-sensitized solar cells and perovskite solar battery.How a kind of energy is designed
Enough be suitble to large area film preparation and streamline operation, improve reliability and production efficiency compacted zone be the invention solves
The technical issues of.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of solar battery compacted zone slurry and its preparation side
Method realizes that solar battery compacted zone is suitble to large area film to prepare with slurry, and streamline operation, raising reliability and life
Produce efficiency.
Technical solution provided by the invention is a kind of solar battery compacted zone slurry, in parts by weight by following
Group is grouped as: 0.1 ~ 10 part of titanium source, 1 ~ 40 part of viscosity modifier, 0.1 ~ 4 part of auxiliary agent, 20 ~ 95 parts of solvent.
Further, the titanium source is made of the titania powder and/or titanium compound of 1nm ~ 10nm；Wherein, described
Titanium compound is tetraisopropyl titanate, titanium acetylacetone and/or titanium tetrachloride.
Further, the viscosity modifier is cellulose, cellulose derivative, cellulosate and/or polyethers.
Further, the solvent is water, alcohol compound and/or terpenoid.
Further, the auxiliary agent includes levelling agent, defoaming agent, dispersing agent or thixotropic agent.
The present invention also provides a kind of preparation method of solar battery compacted zone slurry, the solar battery compacted zone
Above-mentioned solar battery compacted zone slurry is used with the formula of slurry；Preparation method includes:
Step 1, viscosity modifier are added in solvent, are then uniformly mixed it by mechanical stirring or ultrasonic disperse, most
After form clear solution；
Step 2 disperses titania powder to be made into the colloidal sol that mass concentration is 0.1%-2% in a solvent；
Step 2 gained colloidal sol is added in the resulting clear solution of step 1 by step 3, and mass ratio is (1-5): 10, and
It is uniformly mixed by mechanical stirring and forms mixed solution；
Step 3 gained mixed solution is removed solvent by rotary evaporation by step 4, and rotating evaporation temperature is 35 DEG C -60
DEG C, the time is -2 hours 30 minutes, eventually forms mixed liquor；
Auxiliary agent is separately added into step 4 gained mixed liquor by step 5, is mixed finally by mechanical stirring or ultrasonic disperse
Uniformly, solar battery compacted zone slurry is obtained.
Solar battery compacted zone slurry provided by the invention and preparation method thereof is glued by using viscosity additive
It spends adjustable, is suitable for the techniques such as silk-screen printing, slot coated and blade coating, the various auxiliary agents of addition, the stabilization of adjustable slurry
Property, printing when thixotropy, film forming when mobility, the defoaming after film forming, to obtain surfacing, fine and close compacted zone
Film is conducive to the large-scale production of solar battery, densification that is low in cost, being suitable for production solar energy in large area battery
Layer, and simple process is controllable, streamline operation, improves reliability and production efficiency.Wherein, using the titanium dioxide of 1-10nm
Titanium powder adjusts film forming thickness, uses titanium compound for binding material, pass through the works such as silk-screen printing, blade coating as framework material
On various substrates by slurry coating by high temperature sintering, titanium dioxide that is fine and close, being firmly combined with substrate can be obtained in skill
Film.By different coating methods and coating number, the titanium dioxide dense layer film of available different-thickness is being improved
While the consistency of the binding force and film layer of titanium deoxid film and substrate, it is thus also avoided that introduce other inorganic impurities, it can
Mobility when thixotropy when stability, printing to adjust slurry, film forming, the defoaming after film forming, to obtain surface
Smooth, fine and close titanium deoxid film.
