Abstract
The invention discloses a perovskite solar cell and a preparation method for a thermoplastic carbon counter electrode. The perovskite solar cell comprises a photo anode and a thermoplastic carbon counter electrode formed on the photo anode. The preparation method for the thermoplastic carbon counter electrode comprises the following steps of: S1, dissolving and dispersing a conductive carbon material and a thermoplastic polymer in an organic solvent to form an uniform carbon sizing agent; S2, providing a substrate, and forming a carbon sizing agent layer on the surface of the substrate by using the carbon sizing agent; and S3, drying the carbon sizing agent layer to remove the organic solvent in the carbon sizing agent layer, thereby obtaining the thermoplastic carbon counter electrode which is of a thin film shape and is conductive. Since a finished product serving as the thermoplastic carbon counter electrode is prepared in advance and the finished product of the thermoplastic carbon counter electrode is directly hot-pressed onto the photo anode, the perovskite solar cell having good flexibility is prepared, the conversion efficiency and the stability of the perovskite solar cell are improved, and the preparation process is simple and is applicable for perovskite solar cells having various structures.
Description
Technical field
The present invention relates to perovskite technical field of solar batteries, more particularly, to a kind of perovskite solar cell and its heat
The preparation method to electrode for the plasticity carbon.
Background technology
Solar cell is the device directly luminous energy being changed into electric energy by photoelectric effect or Photochemical effects, also known as
For photovoltaic cell.Perovskite solar cell (Perovskite Solar Cells) is a class solar energy more novel at present
Battery, mainly uses similar ABX3(A=CH3NH3 +Deng；B=Pb2+, Sn2+Deng；X=Cl-, Br-, I-Deng) there is perovskite knot
The photovoltaic material of structure, to realize opto-electronic conversion, has the advantages that manufacture craft is simple, raw material sources are extensive, cheap.
The basic structure of perovskite solar cell includes substrate, transparency electrode, electron transport material, perovskite material suction
Photosphere, hole mobile material and electrode.Perovskite solar cell converts light energy into electric energy and can be divided into three main process:
(1) light-absorption layer absorbs the photon of certain energy and produces electron hole pair (exciton)；(2) exciton diffusion to material interface when send out
Raw separation of charge；(3) electronics enters external circuit along electron transport material through electrode, and hole enters along hole mobile material through electrode
External circuit, completes the conversion to electric energy for the luminous energy by load.
The parameter characterizing solar cell properties mainly has short-circuit current density, open-circuit voltage, fill factor, curve factor, opto-electronic conversion
Efficiency.The operating current of unit light-receiving area under short circuit condition for the solar cell is referred to as short-circuit current density (Jsc), now
The voltage of battery output is zero.Solar cell output voltage in the open circuit condition is referred to as open-circuit voltage (Voc), now battery
The electric current of output is zero.Fill factor, curve factor (FF) is peak power output P of unit light-receiving areamaxWith JscVocRatio, FF gets over
Greatly, the performance of solar cell is better.Photoelectric transformation efficiency is peak power output P of unit light-receiving areamaxWith incident too
Sunlight energy density PinPercentage, it is an important output characteristics of solar cell, main and device architecture, hetero-junctions
Characteristic, material character and environment etc. relevant.
In order to realize the industrialization of Ca-Ti ore type solar cell, the problem of current most critical is the steady of raising battery efficiency
Qualitative and reduce the production cost such as technique and raw material.It is one of Ca-Ti ore type solar battery structure important set to electrode
Become part, in current research, in order to realize high efficiency and the stability of battery, typically all utilize the side of vacuum evaporation
Method is fabricated to electrode noble metal gold, and this is all undoubtedly sufficiently expensive in technique and raw material.Conductive carbon material is because having
Good chemical stability, suitable fermi level and the advantage such as cheap and easy to get, have had some seminar successfully at present
By material with carbon element be used in Ca-Ti ore type solar cell on electrode, obtaining preferable effect.
It will be appreciated, however, that the carbon of current report is typically used for the perovskite of no hole transport Rotating fields to electrode
Type solar cell.When this is due to preparing this structure, typically first electron transfer layer is prepared on substrate, on the electron transport layer
Coating porous dielectric layer, then carbon pastes is coated on porous dielectric layer, finally coats extinction layer material, such light-absorption layer material
Material penetrates into electric transmission layer surface through the porous carbon layer of carbon pastes formation and porous dielectric layer, has just obtained electric transmission
The structure of layer-light-absorption layer-insulating barrier-porous carbon layer, due to being prior to perovskite light-absorption layer as carbon to the porous carbon layer of electrode
Be prepared from so that hole transmission layer cannot be added, enter obtained from be no hole transport Rotating fields Ca-Ti ore type too
Sun can battery.
Although the perovskite solar cell of preparation no hole mobile material is conducive to the reduction of battery cost, this
Embody the limitation to electrode preparation method for the current carbon.And calcium titanium is prepared using existing carbon to electrode preparation method
Ore deposit solar cell, battery efficiency is low, stability is poor and is difficult to cell flexible, therefore, develops new more general
The carbon of perovskite solar cell, to electrode preparation method, has high battery conversion efficiency and can adapt to different particular types
Ca-Ti ore type solar cell be very necessary.
