900nm), long exciton diffusion length (100~1000nm) and long carrier lifetime, receive extensively in photovoltaic or photoelectric field
General concern.Traditional hybrid inorganic-organic perovskite material is made of single zwitterion, such as MAPbI3、FAPbC13、
CsPbI3Deng.But one-component perovskite material cannot reach business application requirement, such as MAPbI3(it is more than 160 DEG C) in high temperature
Easily hair reaction is decomposed, CsPbI3High temperatures, and invalid FAPbI is easily generated under room temperature3Huang Xiang.Therefore, zwitterion is mixed
High-performance perovskite material for design thermostabilization and stable structure provides thinking.Such as FAPbI3It is added on a small quantity in perovskite
MA+Be conducive to the black phase FA of inductive formation ambient-temp-stablexMA1-xPbI3(0 ＜ x ＜ 1) perovskite；Cs+Doped with conducive to inhibition
FAxCs1-xPbI3(0 ＜ x ＜ 1) is yellow mutually to be generated, and prepares stable perovskite material.Currently, high performance calcium titanium ore device, is adopted
With mixing zwitterion perovskite material.And perovskite thin film is largely prepared using spin-coating method or vacuum evaporation, is unfavorable for big
The preparation of area and flexible device, is also unfavorable for business promotion.Therefore, it is system by selecting suitable technique and material prescription
Standby high quality large area, flexibility, high yield and the key for promoting perovskite photodetector functionization, also become development calcium titanium
The key technology of mine photodetector practical application.
Roll-to-roll printing technology is a kind of high yield and scale film preparing technology, is widely used in organic solar electricity
The preparation of pond and optical thin film produces, and compatible with various printing technologies, has apparent commercial application foreground.Therefore, it rolls up
Possibility is provided to prepare large area and flexible perovskite thin film to volume printing technology.
Invention content
Problem to be solved by this invention is to overcome the shortcomings of to mention in background technology and defect, provides a kind of photoelectricity and visits
Survey excellent performance, the flexible perovskite photodetector that can prepare on a large scale, further correspondingly provide a kind of technical process it is simple, at
The preparation method of this low above-mentioned flexible perovskite photodetector.
In order to solve the above technical problems, technical solution proposed by the present invention is：
A kind of flexible perovskite photodetector and preparation method of printing, by flexible substrates, mixing zwitterion calcium titanium
Mine light-absorption layer and electrode composition；The perovskite light-absorption layer is the preparation using roll-to-roll printing technology；The mixing negative and positive
The structural formula of ion perovskite is ABX3, wherein A is MA+、FA+And Cs+One or more of, B Pb2+Or Sn2+In one kind
Or several, X I-、Cl-Or Br-One or more of；The perovskite light-absorption layer is located on flexible substrates；The electrode
On perovskite light-absorption layer.
The flexible substrates are polyethylene terephthalate or polyethylene naphthalate or polyimides or paper.
The roll-to-roll printing technology includes roll-to-roll gravure application, roll-to-roll micro- gravure application, volume pair

The present invention is prepared for height to mix zwitterion perovskite material as active layer using roll-to-roll printing technology
The perovskite thin film of quality.The emerging light absorbing material of perovskite material all has in ultraviolet, visible light, near infrared region
Preferable optical absorption characteristics disclosure satisfy that the requirement of photodetection.And the perovskite material of one-component cannot meet practical application
Needs.Therefore, the present invention utilizes material advantage complementarity principle, and mixing zwitterion calcium titanium is prepared using roll-to-roll printing technology
Mine material film, and it is applied to flexible optoelectronic detector.Zwitterion perovskite material is mixed compared with one-component perovskite material to have
There are better structure and thermal stability, can preferably meet application need for a business.In addition, roll-to-roll printing technology is a kind of high
Yield and scale film preparing technology, are adapted to the preparation of large area, flexible perovskite thin film, and the realization for the present invention provides
Basis.
The technical concept total as one, another aspect of the present invention provide a kind of above-mentioned flexible perovskite photodetector
And preparation method, include the following steps：Flexible base is first pre-processed, then prepares BX using roll-to-roll printing precursor solution2
Layer, after heat drying, then roll-to-roll printing coats AX solution, and reaction in-situ generates mixing zwitterion perovskite thin film, heating
Electrode is prepared after drying.
The pretreatment include cleaning treatment, gas purge, sided corona treatment, UV ozone gas disposal, at heating
One or more of reason.It is studied repeatedly by us, it is pre- using one or more of cleaning treatment and gas purge
Handle flexible substrates, be conducive to prepare free from admixture, the low defect density of states and high quality perovskite thin film；And use sided corona treatment
Or one or more of UV ozone gas disposal or heat treatment, the wellability for being conducive to substrate is promoted, to improve pioneer
Liquid solution is sprawled substrate surface, finally obtains the perovskite thin film of high adhesion strength, surfacing, high quality.
The rate of the roll-to-roll printing is between 0.2m/min~100m/min.
The precursor is the solution of the ingredient containing AX.It is studied according to us, spin-coating method prepares perovskite with mode of printing
Film has two different dry mechanism.For spin-coating method, solvent is volatilized in spin coating process with faster speed, and is printed
Mode is then volatilized in a manner of slower.Therefore, in the dry printing process of slow curing, BX2It can be migrated so as to cause mistake
The crystal grain of crystallization is spent, and then leads to coarse and discontinuous BX2Film.We have discovered that a small amount of AX is incorporated into precursor
The perovskite thin film of high quality can be effectively prepared in solution.This is because AX is incorporated into precursor solvent, calcium is formd
Titanium ore interphase, to prevent BX2Migration.Also, since perovskite interphase is with regard to unstable, and finally will directly simultaneously
Perovskite material is promptly converted into without forming other by-products.Therefore, AX is as additive, to realizing that roll-to-roll printing is made
The perovskite thin film of standby large area and high quality is most important.
The mixing zwitterion perovskite thin film can be applied to photodetector, solar cell, thin film transistor (TFT),
Photo luminescent devices.
Compared with the prior art, the advantages of the present invention are as follows：The flexible perovskite photodetector of the present invention, using volume pair
Volume technology prepares mixing zwitterion perovskite thin film, and large area and fexible film are more suitable for compared with spin-coating method and vacuum vapour deposition
With the preparation of device；It is more suitable for continuous and prepare with scale film and device compared with ink-jet printing technology；Compared with knife coating and screen printing
Brush is more easy to obtain the perovskite thin film of high quality.On the whole, photodetector of the invention, while there is large area and flexibility
Distinguishing feature, substantially improve the large-scale production ability of perovskite photodetector, to improve perovskite photodetector
Functionization is of great significance.
