Property progress.Since perovskite material absorptivity is high, band gap is controllable, bipolarity (can transmit electronics but also transporting holes), expands
The advantages that scattered length is longer and carrier mobility is high, makes perovskite material possess preferable photoelectric properties, perovskite solar energy
High power conversion efficiency may be implemented in battery.But power converts high perovskite solar battery in high-purity at present
It is prepared in glove box, and using expensive hole transmission layer and noble metal electrode, the problems such as preparation cost is high, stability is poor is not
Conducive to industrialization large-scale production.
Chinese patent CN105870335A discloses a kind of simple perovskite solar battery of preparation process, with mesoporous branch
Based on frame structure devices, device architecture is simplified, the expensive noble metal electrode of carbon electrode replacement changes in certain degree
It has been apt to the performance of perovskite solar battery.But mesoporous shelf layer and carbon electrode will successively pass through silk-screen printing, calcining preparation
It after porous film electrode, is put into glove box, perovskite precursor liquid is added dropwise, after penetrating into mesoporous layer, solvent flashing, crystallization,
Complete preparation.Later stage of preparation uses glove box, and preparation process is not all of to be completed under natural air.
Chinese patent CN106601833A disclose a kind of inexpensive high stability solar battery suitable for production and its
Preparation method.Although perovskite solar battery power conversion efficiency has been more than 16% or more, vacuum thermal evaporation, spray are used
The methods of apply, deposit, last vacuum evaporation metal electrode, there are device preparation cost height and preparation process condition to require high, behaviour
Make the problems such as complicated.Although foregoing invention patent gradually constantly promotes perovskite solar battery to industrialization, calcium titanium
Mine solar battery is to oxygen, moisture sensitivity, and defect is easier to be formed, and causes perovskite solar cell stability poor.It seeks
Looking for stable perovskite preparation method of solar battery is the target of the field concerted effort.
Chinese patent CN106328813A discloses a kind of high stability and mixes caesium Ca-Ti ore type solar battery and its preparation
Method.The patent application improves device stability by the doping of cation to a certain extent, but introduces expensive 2,
2', 7,7'- tetra- [N, N- bis- (4- methoxyphenyl) amino] -9,9'- spiral shell two fluorenes (Spiro-MeOTAD) base hole transmission layer.It causes
It is high to make device cost, and stability is still very low.
It can be seen that its crystallinity and stabilization can be enhanced, while adjusting calcium by perovskite material cation doping
Titanium ore material forbidden bandwidth, may finally improve perovskite solar battery power conversion efficiency and stability, therefore, for upper
The deficiencies in the prior art are stated, the present invention provides one kind under natural air, the high stability perovskite sun based on carbon electrode
It can battery and its simple liquid phase preparation process at low cost.
Summary of the invention
It is an object of the invention to overcome perovskite solar battery preparation aspect the deficiencies in the prior art, device is proposed
Structure optimization does not use expensive material, using the perovskite of simple liquid phase method preparation high stability under the conditions of natural air
The scheme of solar battery.Perovskite solar battery prepared by the present invention has power conversion efficiency high, in natural air item
