Description
Technical Field
The invention relates to the technical field of photovoltaics, in particular to a perovskite solar cell, a production method of the perovskite solar cell and a perovskite cell module.
Background
Perovskite solar cells have received much attention because of their advantages of high photoelectric conversion efficiency and low cost.
In the prior art, the perovskite material is easy to degrade under the water-oxygen environment condition, and phase defects, interface defects and ion migration in the perovskite material easily cause poor stability of the perovskite solar cell. Therefore, the following methods are generally required to improve the stability of perovskite solar cells: one method is to use device encapsulation to prevent water oxygen from invading the interior of the perovskite solar cell, and the other method is to use passivation agents to reduce the internal defects of the perovskite material.
However, the device packaging can only prevent the cell finished product from being invaded by water and oxygen, and the water vapor absorbed in the cell preparation process cannot be avoided, while the common passivation reagent can reduce the internal defects of the perovskite material, but contains hydrophilic groups, so that the resistance to humidity is limited, and the perovskite solar cell with higher stability is not easy to obtain.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a schematic structural diagram of a perovskite solar cell of the present invention is shown, and as shown in fig. 1, the perovskite solar cell may specifically include: a substrate 10, and a conductive layer 11, a first carrier transport layer 12, a perovskite absorption layer 13, a first fluorinated organic compound layer 14, a second carrier transport layer 15, and an electrode 16 formed in this order on the substrate 10; among them, the fluorinated organic compound forming the first fluorinated organic compound layer 14 includes a polar group.
The fluorinated organic compound may have the structure:
wherein S can be a linear or branched saturated alkyl group or an unsaturated alkyl group, n is the number of carbon atoms included in S, n is an integer of 1 to 20, E is a polar group, the polar group includes at least one of a nitrogen atom, an oxygen atom, a sulfur atom and a phosphorus atom, and F is a hydrophobic fluoro group.
In practical applications, since the polar group E contains at least one of nitrogen atom, oxygen atom, sulfur atom and phosphorus atom, the polar group E can be used to interact with lead and/or halogen ions and the like in the perovskite absorption layer 13, so as to limit the migration of the ions, passivate the interface defects of the perovskite absorption layer 13, and further improve the stability of the perovskite solar cell. And the fluoro group F has the advantage of hydrophobicity, so that the perovskite absorption layer 13 can be protected, external water vapor is prevented from invading the perovskite absorption layer 13, and the stability of the perovskite solar cell is improved.
Alternatively, the polar group E may be selected from: at least one of amino, sulfydryl, hydroxyl, sulfonic acid group, sulfonamide, carboxylic acid, aldehyde group, ester group, amide group, phosphate group, hypophosphite group and corresponding salt compounds thereof, so that the polar group E can well interact with ions in the perovskite absorption layer 13, the migration of the ions is limited, and the interface defects of the perovskite absorption layer 13 are passivated. The fluoro group F may be selected from: at least one of fluoroalkyl group, fluorophenyl group and fluorinated naphthyl group, so that the first fluorinated organic compound layer 14 has better hydrophobicity.
Alternatively, the fluoro-organic compound may be selected from: at least one of fluoro thiol, fluoro sulfonamide, fluoro aliphatic amine, fluoro aliphatic ammonium salt, fluoro aromatic amine, and fluoro aromatic ammonium salt, so that the first fluoro organic compound layer 14 has a good hydrophobic property, can restrict ion migration in the perovskite absorption layer 13, and can passivate interfacial defects of the perovskite absorption layer 13.
In particular, the substrate 10 may serve as a support host for the perovskite solar cell, which may be grown on the substrate 10.
In some embodiments of the invention, the perovskite solar cell is a single cell, in which case the matrix 10 may be a substrate, which may be selected from: at least one of glass, polyethylene terephthalate and polyimide.
In other embodiments of the present invention, the perovskite solar cell is a tandem cell, such as a perovskite-crystalline silicon tandem cell, a perovskite-perovskite tandem cell, a perovskite-copper indium gallium selenide cell, and the like, in which case the substrate 10 may be a bottom cell, which may include at least one of a crystalline silicon cell, a perovskite cell, and a copper indium gallium selenide cell. For example, in the case where the laminate battery is a perovskite-crystalline silicon laminate battery, the underlying battery may be a crystalline silicon battery. As another example, where the laminate battery is a perovskite-perovskite laminate battery, the base battery may be a perovskite battery.
Specifically, the conductive layer 11 may be a transparent conductive layer formed on the substrate 10 by using an atmospheric pressure chemical vapor deposition process, and the conductive layer 11 may play a role in assisting carrier transmission, and may transmit light, so as to further improve the photoelectric conversion efficiency.
Illustratively, the material of the conductive layer 11 may be selected from: the thickness of the conductive layer 11 may be 50-1000nm, and the specific material and thickness of the conductive layer 11 in the embodiment of the present invention are not limited.
In the embodiment of the present invention, the first carrier transport layer 12 may be used to realize transport of the first carrier, and the second carrier transport layer 15 may be used to realize transport of the second carrier. The first carrier may be selected from one of an electron or a hole, and the second carrier may be selected from the other of an electron or a hole. That is, when the first carrier is an electron, the second carrier must be a hole; when the second carrier is an electron, then the first carrier must be a hole.
The first carrier transport layer 12 and the second carrier transport layer 15 are specifically an electron transport layer or a hole transport layer, and need to be determined according to the type of the perovskite solar cell. In the case where the perovskite solar cell is a formal perovskite solar cell, the first carrier transport layer 12 is an electron transport layer, and the second carrier transport layer 15 is a hole transport layer. In the case where the perovskite solar cell is a trans-perovskite solar cell, the first carrier transport layer 12 is a hole transport layer, and the second carrier transport layer 15 is an electron transport layer.
In some embodiments of the present invention, the material of the electron transport layer may be selected from: at least one of titanium oxide and tin oxide, and the thickness of the electron transport layer can be 5-100 nm. The hole transport layer can be selected from: at least one of 2,2',7,7' -tetrakis [ N, N-bis (4-methoxyphenyl) amino ] -9,9' -spirobifluorene (Spiro-OMeTAD), poly [ bis (4-phenyl) (2,4, 6-trimethylphenyl) amine ] (PTAA), copper iodide (CuI), and the thickness of the hole transport layer may be in a range of 10 to 150 nm.
In practical applications, the perovskite absorption layer 13 may serve as a light absorption layer. Specifically, the perovskite absorption layer 13 first absorbs photons to generate electron-hole pairs when irradiated with sunlight. These carriers either become free carriers or form excitons due to differences in exciton binding energy of the perovskite material. Furthermore, because these perovskite materials tend to have a lower probability of carrier recombination and higher carrier mobility, the diffusion distance and lifetime of carriers are longer. These non-recombined electrons and holes are then collected by the electron transport layer and the hole transport layer, respectively, i.e. electrons are transported from the perovskite absorption layer 13 to the electron transport layer and finally collected by the conductive layer 11; holes are transported from the perovskite absorption layer 13 to the hole transport layer and finally collected by the electrode 16. Finally, a photocurrent is generated by a circuit connecting the conductive layer 11 and the electrode 16, completing photoelectric conversion.
In particular, the perovskite absorption layer 13 may be made of a perovskite material having the chemical formula ABZmY3-mWherein the monovalent cation a may be selected from: CH (CH)3NH3、C4H9NH3、NH2＝CHNH2At least one of Cs; the divalent metal ion B can be at least one selected from Pb and Sn; z is halogen elements such as Cl, Br or I, Y is halogen elements such as Cl, Br or I, and Z and Y are not the same element at the same time; m is 1, 2 or 3. In order to achieve better absorption of sunlight, the thickness of the perovskite absorption layer 13 may range from 200-1500 nm.
Specifically, the electrode 16 may be used to collect holes and conduct electricity, and the electrode 16 may be formed by printing, deposition, or the like. The electrode 16 may be a metal electrode, which may be selected from: at least one of a copper electrode, a silver electrode, or a gold electrode to make the electrode 16 conductive. The thickness of the electrode 16 may range from 10-400 nm. The specific material and thickness of the electrode 16 in the embodiment of the present invention may not be limited.
In the embodiment of the present invention, the first fluorinated organic compound layer 14 may be provided between the perovskite absorption layer 13 and the second carrier transport layer 15, and the fluorinated organic compound forming the first fluorinated organic compound layer 15 may include a polar group including at least one of a nitrogen atom, an oxygen atom, a sulfur atom, and a phosphorus atom.
Specifically, the fluorinated organic compound may be an elemental organic compound in which hydrogen bonded to a carbon atom in an organic compound molecule is substituted with fluorine. Compounds in which all carbon-hydrogen bonds in the molecule are converted to carbon-fluorine bonds are referred to as perfluorinated organic compounds, and partially substituted compounds are referred to as monofluorinated or polyfluorinated organic compounds. Because the fluorinated organic compound contains hydrophobic fluorinated groups, the first fluorinated organic compound layer 14 can protect the perovskite absorption layer 13 by utilizing the advantage of high hydrophobicity of the fluorinated organic compound, prevent external water vapor from invading the perovskite absorption layer 13, and improve the stability of the perovskite solar cell.
Alternatively, the fluoro-organic compound may be selected from: at least one of perfluorinated organic compounds, polyfluoro organic compounds, and monofluorinated organic compounds, so that the first fluorinated organic compound layer 14 has hydrophobic properties.
It is understood that since the hydrophobic perfluoro organic compound and the hydrophobic polyfluoro organic compound have more fluoro groups and the hydrophobic property is more excellent, the hydrophobic perfluoro organic compound or the hydrophobic polyfluoro organic compound may be preferably used to form the first fluoro organic compound layer 14 in a specific application.
In the embodiment of the present invention, the fluorinated organic compound may include a polar group, and the polar group may be selected from: at least one of amino, mercapto and sulfonamide. In a specific application, the polar group can be used for interacting with lead and/or halogen ions and the like in the perovskite absorption layer 13, limiting the migration of the ions, passivating the interface defects of the perovskite absorption layer 13 and further improving the stability of the perovskite solar cell.
Alternatively, the thickness of the first fluoroorganic compound layer 14 is 1-50 nm. For example, in the case where the fluorinated organic compound layer is dense, the thickness of the first fluorinated organic compound layer 14 may be only a few molecular layers, that is, the thickness of the first fluorinated organic compound layer 14 may be only about a few nanometers, so that the thickness of the first fluorinated organic compound layer 14 is thin.
Referring to fig. 2, there is shown a schematic structural view of another perovskite solar cell of the present invention, which may further include, as shown in fig. 2: a second fluorinated organic compound layer 17, the second fluorinated organic compound layer 17 being disposed between the perovskite absorption layer 13 and the first carrier transport layer 12.
Specifically, the fluoro organic compound forming the second fluoro organic compound layer has a structure of:
wherein S may be a linear or branched hydrocarbon group, n is the number of carbon atoms included in S, n is an integer of 1 to 20, E is a polar group including at least one of a nitrogen atom, an oxygen atom, a sulfur atom and a phosphorus atom, and F is a hydrophobic fluoro group.
In the embodiment of the invention, the second fluorinated organic compound layer 17 can protect the perovskite absorption layer 13 by utilizing the advantage of high hydrophobicity of the fluorinated organic compound, so that external water vapor is prevented from invading the perovskite absorption layer 13 from the side close to the substrate 10, and the stability of the perovskite solar cell is improved. Moreover, the polar group in the second fluorinated organic compound layer 17 can be used for interacting with the ions in the perovskite absorption layer 13 to limit the migration of the ions, and can also passivate the interface defects of the perovskite absorption layer 13, thereby further improving the stability of the perovskite solar cell.
It will be appreciated that, because of the good water resistance of the substrate 10, in a particular application, it is preferable to provide the first fluorinated organic compound layer 14 on the side of the perovskite absorption layer 13 remote from the substrate 10 to prevent external moisture from entering the perovskite absorption layer 13 on the side remote from the substrate 10. Of course, the second fluorinated organic compound layer 17 is provided on the side of the perovskite absorption layer 13 close to the substrate 10, so that external moisture can be better prevented from entering the perovskite absorption layer 13, and furthermore, ion migration in the perovskite absorption layer 13 can be better limited and interface defects of the perovskite absorption layer 13 can be passivated.
Alternatively, in the perovskite solar cell according to the embodiment of the present invention, the first fluorinated organic compound layer 14 and/or the second fluorinated organic compound layer 17 may be disposed, that is, the fluorinated organic compound layer may be disposed on one side or both sides of the perovskite absorption layer 13, which is not limited in the embodiment of the present invention.
In some alternative embodiments of the invention, the perovskite absorption layer 13 may comprise only perovskite material, and in other alternative embodiments of the invention, the perovskite absorption layer 13 may comprise: a perovskite material and a doped fluorinated organic compound 130. That is, the fluorinated organic compound 130 containing a polar group is doped in the perovskite material, and the perovskite absorption layer 13 is formed using the doped material.
Specifically, the fluorinated organic compound has the advantage of high hydrophobicity, and the polar group in the fluorinated organic compound can be used for passivating the perovskite material and the internal grain boundary defects, so that after the fluorinated organic compound is doped with the perovskite material, the perovskite absorption layer 13 can have high hydrophobicity, the grain boundary defects in the perovskite absorption layer 13 can be passivated, and the stability of the perovskite solar cell is improved.
It is understood that, in practical applications, in the case that the perovskite absorption layer 13 includes a perovskite material and a doped fluorinated organic compound, since the perovskite absorption layer 13 itself has a better hydrophobic property, internal grain boundary defects can also be passivated, and the stability of the perovskite absorption layer 13 is better, the fluorinated organic compound layer on one side or both sides of the perovskite absorption layer 13 can be eliminated according to practical situations, so as to simplify the structure of the perovskite solar cell, so as to obtain the perovskite solar cell shown in fig. 3 or fig. 4.
Optionally, in case the perovskite material is doped with the organic fluoro compound, the ratio of the molar mass of the fluoro organic compound to the molar mass of the monovalent cation a is between 0.5 and 40, so that a better doping effect of the perovskite absorption layer 13 is obtained.
Illustratively, the molar doping ratio of the fluorinated organic compound is: x% ═ MThe fluoro compound/MAWherein, the value of x can be 0.5-40.
For example, in the case where the perovskite material is made of Formamidinium Iodide (FAI), Methylammonium bromide (MABr), and Methylammonium chloride (MACl), MACan be MFAI、MMABrAnd MMAClAnd (4) summing.
In summary, the perovskite solar cell according to the embodiment of the invention has at least the following advantages:
in the embodiment of the present invention, since the first fluorinated organic compound layer is provided between the perovskite absorption layer and the second carrier transport layer, the fluorinated organic compound forming the first fluorinated organic compound layer includes a polar group. On one hand, the first fluorinated organic compound layer can protect the perovskite absorption layer by utilizing the advantage of high hydrophobicity of the fluorinated organic compound, prevent external water vapor from invading the perovskite absorption layer, and improve the stability of the perovskite solar cell. On the other hand, as the fluorinated organic compound comprises a polar group, nitrogen atoms, oxygen atoms, sulfur atoms and phosphorus atoms in the polar group can be used for interacting with ions in the perovskite absorption layer, so that the migration of the ions is limited, the interface defects of the perovskite absorption layer can be passivated, and the stability of the perovskite solar cell is further improved.
