Technical Field

[0001] The utility model relates to the technical field of perovskite solar cells, and more particularly, to an evaporation device. Background Art

[0002] The preparation methods of perovskite solar cells mainly include vacuum deposition method and solution deposition method. The vacuum deposition method refers to heating an organic material in a vacuum condition to vaporize the organic material, and the vaporized organic material diffuses and deposits on a substrate and reacts with lead halide to realize the preparation of a perovskite solar cell.

[0003] However, some organic materials are prone to decomposition during the heating process, resulting in the deterioration of some organic materials (FAX, MAX, X is a halogen) required for perovskite, reducing the performance of the perovskite battery and causing waste of some organic materials. Secondly, there is a problem of dispersion during the evaporation of organic salts, that is, the vaporized organic materials surround the evaporation source rather than diffuse towards the substrate, resulting in very poor uniformity of the organic salt film deposited by the evaporation method, reducing the performance and yield rate of the perovskite battery.

[0025] Please refer to Figures 1 to 3 Figures 1 to 3 , the present utility model provides an evaporation device, including: a heating element and a heating box 20. The heating element has an on state and an off state. The heating box 20 has a heating chamber 21 for accommodating the particulate matter to be evaporated; a first power supply component 3 is disposed in the heating chamber 21, and at least a part of the first power supply component 3 contacts the particulate matter to be evaporated, so that the first power supply component 3 applies a first charge to the particulate matter to be evaporated; a detection component is used to detect the real-time charge amount of the particulate matter to be evaporated. The detection component is communicatively connected to the heating element, so that when the real-time charge amount detected by the detection component is greater than zero, the heating element switches to the on state; wherein, when the heating element is in the on state, the heating element heats the heating box 20, so that the particulate matter to be evaporated in the heating chamber 21 is transformed from a solid state to a gaseous state.

[0026] The evaporation device of the present utility model includes a heating element, a heating box 20, a first power supply component 3 and a detection component. The heating box 20 has a heating chamber 21 for accommodating the particulate matter to be evaporated. First, the first power supply component 3 applies a first charge to the particulate matter to be evaporated. When the real-time charge amount of the particulate matter to be evaporated detected by the detection component is greater than zero, then the heating element switches to the on state and starts to heat the particulate matter to be evaporated. Such a setting ensures that the particulate matter to be evaporated heated by the heating element carries a first charge. At the same time, the first charge can effectively inhibit the thermal decomposition of the particulate matter to be evaporated, thereby solving the technical problem of the low performance of the perovskite battery prepared by evaporating organic salts and improving the evaporation efficiency of the evaporation device.

[0027] Specifically, the heating box 20 is a crucible; the particulate matter to be evaporated is an organic salt, the gaseous particulate matter to be evaporated is an organic salt vapor, and the solid particulate matter to be evaporated is an organic salt solid.

[0028] In this embodiment, the evaporation device further includes a substrate 4, a back electrode plate 7, and a second power supply component. The substrate 4 is disposed above the heating box 20 in the vertical direction. The back electrode plate 7 is disposed above the substrate 4 and used to generate an electric field. The second power supply component is used to apply a second charge to the back electrode plate 7 and the substrate 4. The first charge and the second charge have opposite attributes, so that the gaseous particulate matter to be evaporated is attracted by the back electrode plate 7 and the substrate 4, so that the gaseous particulate matter to be evaporated moves in the vertical direction toward the direction close to the back electrode plate 7 and the substrate 4, so that the gaseous particulate matter to be evaporated adheres to the substrate 4.

[0029] Specifically, by applying power to the back electrode plate 7 above the substrate 4 through the second power supply component to generate an electric field, the charged gaseous particulate matter to be evaporated is driven by the electric field to move uniformly from bottom to top and finally deposited on the substrate 4, improving the uniformity of the organic salt deposition, thereby solving the technical problem of the low performance of the perovskite battery prepared by evaporating the organic salt.

[0030] Specifically, during the evaporation of FAI and MAI, which are components of the perovskite, the organic salt vapor is prone to agglomerate near the evaporation source and the crystal oscillator probe, rather than uniformly moving around the evaporation source outlet in all directions. By applying charges with different attributes to the back electrode plate 7 and the particulate matter to be evaporated, the back electrode plate 7 can attract the gaseous particulate matter to be evaporated, so that the gaseous particulate matter to be evaporated adheres to the substrate 4; by uniformly heating the organic salt solid to generate uniform organic salt vapor, under the drive of the uniform electric field, the charged organic salt vapor moves toward the back electrode plate 7 above the substrate 4 and finally adheres to the substrate 4, thereby solving the problem of the dispersion of the organic salt during the evaporation process.

[0031] Specifically, the structure of the third power supply component is the same as that of the second power supply component and the first power supply component 3.

[0032] During specific implementation, first, the first power supply component 3 applies a first charge to the particulate matter to be evaporated, and the second power supply component applies a second charge to the back electrode plate 7. When the real-time charge of the particulate matter to be evaporated detected by the detection component is greater than zero, then the heating component switches to the on state and starts to heat the particulate matter to be evaporated. The particulate matter to be evaporated changes from solid state to gaseous state, and the gaseous particulate matter to be evaporated is attracted by the back electrode plate 7 to adhere to the substrate 4.

[0033] Optionally, the first charge is a positive charge and the second charge is a negative charge; or the first charge is a negative charge and the second charge is a positive charge.

[0034] In this embodiment, the evaporation device further includes a conductive wire 2. The first power supply component 3 includes a plurality of first power supply elements, which are arranged at intervals in the vertical direction. One end of the conductive wire 2 is connected to an external power supply, and the other end of the conductive wire 2 is electrically connected to the uppermost first power supply element. Any two adjacent first power supply elements are electrically connected. When the heating element is in the off state, at least one first power supply element is immersed in the solid particulate matter to be evaporated.

[0035] Specifically, the conductive wire 2 is used to electrically connect the external power supply and the first power supply element to make the first power supply element energized. By setting any two adjacent first power supply elements to be electrically connected and at least one first power supply element being immersed in the solid particulate matter to be evaporated, it is ensured that the first power supply element can smoothly apply the first charge to the solid particulate matter to be evaporated, ensuring that the solid particulate matter to be evaporated carries the first charge.

[0036] In this embodiment, each first power supply element includes a first power supply section 31, a second power supply section 32, a third power supply section 33, and a fourth power supply section 34 that are connected to each other. Both the first power supply section 31 and the third power supply section 33 extend along a first preset direction, both the second power supply section 32 and the fourth power supply section 34 extend along a second preset direction, and the first power supply section 31 and the third power supply section 33 are arranged at intervals in the second preset direction between the second power supply section 32 and the fourth power supply section 34.

[0037] Specifically, arranging a plurality of first power supply elements at intervals in the vertical direction can prevent the amount of electric charge applied by the first power supply component 3 to the particulate matter to be evaporated from being small. When there are more particulate matters to be evaporated, some of the particulate matters to be evaporated cannot be applied with the first charge, resulting in some of the organic salt vapors carrying the first charge moving towards the back electrode plate under the action of the uniform electric field and finally adhering to the substrate 4, while some of the organic salt vapors are still uncharged and there is still a problem of uneven deposition due to dispersion. With a plurality of first power supply elements, the organic salt solid is fully charged, and then uniform charged organic salt vapor is produced, which is uniformly deposited on the substrate 4 under the action of the electric field, so that the organic salt is uniformly deposited on the substrate 4. At the same time, making the organic salt solid fully charged can prevent some uncharged organic salt solids from being thermally decomposed and deteriorated, thereby improving the evaporation efficiency of the evaporation device.

[0038] In this embodiment, the first power supply component 3 further includes a third power supply component. The third power supply component includes a fifth power supply section 35, a sixth power supply section 36, a seventh power supply section 37, and an eighth power supply section 38 that are connected to each other. Both the fifth power supply section 35 and the seventh power supply section 37 extend along a second preset direction. Both the sixth power supply section 36 and the eighth power supply section 38 extend along the vertical direction. The fifth power supply section 35 and the seventh power supply section 37 are arranged at intervals along the vertical direction between the sixth power supply section 36 and the eighth power supply section 38. Among them, the first preset direction, the second preset direction, and the vertical direction are set perpendicular to each other in pairs. Both ends of the fifth power supply section 35 are electrically connected to the first power supply section 31 and the third power supply section 33 of the first power supply component located at the uppermost position respectively. Both ends of the seventh power supply section 37 are electrically connected to the first power supply section 31 and the third power supply section 33 of the first power supply component located at the lowermost position respectively. The first power supply section 31 of each first power supply component is electrically connected to the sixth power supply section 36, and the third power supply section 33 of each first power supply component is electrically connected to the eighth power supply section 38, so that any two adjacent first power supply components are electrically connected.

[0039] In this embodiment, the first power supply component 3 further includes a fourth power supply component. The fourth power supply component includes a ninth power supply section 39, a tenth power supply section 40, an eleventh power supply section, and a twelfth power supply section 42 that are connected to each other. Both the ninth power supply section 39 and the eleventh power supply section extend along the first preset direction. Both the tenth power supply section 40 and the twelfth power supply section 42 extend along the vertical direction. The ninth power supply section 39 and the eleventh power supply section are arranged at intervals along the vertical direction between the tenth power supply section 40 and the twelfth power supply section 42. Both ends of the ninth power supply section 39 are electrically connected to the second power supply section 32 and the fourth power supply section 34 of the first power supply component located at the uppermost position respectively. Both ends of the eleventh power supply section are electrically connected to the second power supply section 32 and the fourth power supply section 34 of the first power supply component located at the lowermost position respectively. The second power supply section 32 of each first power supply component is electrically connected to the tenth power supply section 40, and the fourth power supply section 34 of each first power supply component is electrically connected to the twelfth power supply section 42, so that any two adjacent first power supply components are electrically connected.

[0040] Specifically, the third power supply component and the fourth power supply component are used to connect any two adjacent first power supply components, ensuring that any two adjacent first power supply components are electrically connected, and ensuring that the first power supply component can smoothly apply the first charge to the particulate matter to be evaporated.

[0041] In this embodiment, the evaporation device further includes a first circuit, a controller, and a switch. Both ends of the first circuit are respectively connected to the heating element and an external power supply. The switch is arranged on the first circuit. The controller is communicatively connected to the detection component, and the controller is communicatively connected to the switch, so that the controller controls the opening and closing of the switch to control the on-off of the first circuit, and controls the heating element to switch between the on state and the off state.

[0042] Specifically, through communication connection between the controller and the switch, the detection component feeds back the detection result to the controller. Before the first power-on component 3 starts to work, the switch is open, the first circuit is disconnected, and the heating component is powered off and in the off state. The controller determines that the real-time charge of the particulate matter to be evaporated is equal to zero. Then the first power-on component 3 starts to work. When the controller determines that the real-time charge of the particulate matter to be evaporated is greater than zero, the controller controls the switch to close, so that the first circuit is connected, and the heating component is powered on and switched to the on state.

[0043] Optionally, the heating component is an electric furnace or an electric hot plate.

[0044] In this embodiment, the heating box 20 includes a bottom wall 22 and four side walls 23. The four side walls 23 surround the bottom wall 22. The bottom wall 22 and the four side walls 23 together enclose a heating cavity 21. Each side wall 23 extends in the vertical direction. The heating component is arranged below the bottom wall 22 to heat the bottom wall 22 when the heating component is in the on state.

[0045] Specifically, the bottom wall 22 and the four side walls 23 together enclose the heating cavity 21 to accommodate the particulate matter to be evaporated; when the heating component is in the on state, the bottom wall 22 is used to transfer the heat from the heating component to the particulate matter to be evaporated, so that the particulate matter to be evaporated is smoothly converted from solid state to gaseous state.

[0046] In this embodiment, the evaporation device further includes a separation membrane 5. A plurality of through holes 6 are arranged at intervals on the separation membrane 5. The separation membrane 5 is detachably arranged on one side of the substrate 4 close to the heating box 20. The third power-on component is electrically connected to the separation membrane 5. The third power-on component is used to apply a first charge to the separation membrane 5 so that the gaseous particulate matter to be evaporated adheres to the substrate 4 through the through holes 6.

[0047] Specifically, when the particulate matter to be evaporated is an organic substance, the separation membrane 5 is removed, and the gaseous particulate matter to be evaporated directly contacts the substrate 4; when the particulate matter to be evaporated is a metal, the separation membrane 5 is arranged on one side of the substrate 4 close to the heating box 20, so that the gaseous particulate matter to be evaporated adheres to the substrate 4 through the through holes 6. Since the plurality of through holes 6 are linearly arranged on the separation membrane 5, the gaseous particulate matter to be evaporated is linearly arranged on the substrate 4 to form a wire electrode. By applying a first charge to the separation membrane 5 through the third power-on component, the separation membrane 5 and the gaseous particulate matter to be evaporated repel each other, avoiding the gaseous particulate matter to be evaporated from adhering to the separation membrane 5, thereby reducing the metal layer deposited on the separation membrane 5, and further reducing the cleaning and replacement frequency of the separation membrane 5, and reducing the use cost of the evaporation device.

[0048] In this embodiment, the detection component is an electroscope. Such a setting ensures the detection reliability of the detection component for the charge of the particulate matter to be evaporated.

[0049] Optionally, there are multiple detection components, which respectively detect the to-be-evaporated particulate matters at different positions in the heating chamber 21. When the real-time charge amounts detected by each detection component are all greater than zero, the heating component switches to the on state. Such a setting can prevent some to-be-evaporated particles from being heated without carrying the first charge.

[0050] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0051] The evaporation device of the present utility model includes a heating component, a heating box 20, a first power supply component 3, a detection component, a substrate 4, a back electrode plate 7, and a second power supply component. The heating box 20 has a heating chamber 21 for accommodating the to-be-evaporated particulate matters. First, the first power supply component 3 applies a first charge to the to-be-evaporated particulate matters. When the real-time charge amount of the to-be-evaporated particulate matters detected by the detection component is greater than zero, then the heating component switches to the on state and starts to heat the to-be-evaporated particles. Such a setting ensures that the to-be-evaporated particulate matters heated by the heating component carry the first charge. By applying power to the back electrode plate 7 above the substrate 4 through the second power supply component to generate an electric field, the organic salt vapor carrying the first charge is driven by the electric field to move uniformly towards the back electrode plate 7 and finally adheres to the substrate 4, solving the problem of uneven deposition of organic salts due to diffusivity during the evaporation process. At the same time, the first charge can effectively inhibit the thermal decomposition of the to-be-evaporated particulate matters, solving the problem that some organic materials are prone to deterioration during the heating process, and further solving the technical problem of the low performance of perovskite batteries prepared by evaporating organic salts, thereby improving the evaporation efficiency of the evaporation device.
