Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a perovskite battery module and a manufacturing method thereof. Background Art

[0002] At present, in the production process of traditional perovskite battery components, three laser scribings, P1, P2 and P3, are generally required to form a perovskite battery layer structure with multiple sub-batteries connected in series. Among them, the P1 laser scribing is mainly used to cut the transparent conductive layer on the transparent substrate, which has no effect on the perovskite battery layer, while the P2 and P3 laser scribings are mainly used to cut the perovskite battery layer to form multiple sub-battery structures. Therefore, the P2 and P3 laser scribings will damage the perovskite light-absorbing layer, and the side of the perovskite light-absorbing layer at the laser scribing is exposed to the air, which will reduce the stability of the perovskite battery component.

[0003] At the same time, the packaging process of the perovskite battery module is: the transparent substrate coated with the perovskite battery layer, the packaging layer (packaging film), and the packaging glass (backplane) are laid out and placed in a laminator for vacuum lamination for 15 to 20 minutes. However, during the lamination process, the packaging film will melt and flow into the P3 laser-scribed lanes connecting adjacent sub-cells. The packaging film will react with the organic / inorganic layer in the P3 laser-scribed lanes during high temperature and cooling, which will further cause the perovskite battery layer to experience electrical performance degradation, decreased stability, and affect the service life of the battery module. Summary of the invention

The width of the second insulating gate 4 in the first direction is set to 100-1000nm;

[0055] A plurality of electrical connection gates 5 are arranged on each transparent conductive block 23 along the second direction and are located between the second spacing groove 22 and the second insulating gate 4.

[0059] and a back plate, which is stacked on the packaging layer;

[0061] Example 2

[0062] This embodiment 2 provides a method for manufacturing a perovskite battery assembly, which is used to manufacture the perovskite battery assembly of embodiment 1. The method comprises the following steps:

[0063] S1, providing a transparent substrate 1, and defining a first direction and a second direction thereon;

[0064] S2, preparing a transparent conductive layer 2 on the transparent substrate 1, and then performing P1 laser scribing three times along the first direction to form three first spacing grooves 21, and then performing P1 laser scribing twice along the second direction to form two second spacing grooves 22, and using the first spacing grooves 21 and the second spacing grooves 22 formed by these laser scribing to cut the transparent conductive layer 2, so that the transparent conductive layer 2 with an original whole layer structure can be divided into 12 transparent conductive blocks 23;

[0065] S3, cleaning and drying the transparent substrate 1 after the P1 laser scribing, and then using the designed mask to mask the area corresponding to the electrical connection grid 5, the sub-cell 63, the back electrode 7 and the bus bar 8, and then preparing four first insulating grids 3 on each transparent conductive block 23 along the first direction and preparing the first insulating grid 3 in the first spacing groove 21, and then preparing one second insulating grid 4 on each transparent conductive block 23 along the second direction and preparing the second insulating grid 4 in the second spacing groove 22; specifically, any one or two methods of thermal evaporation, deposition, printing or coating can be used to prepare the first insulating grid 3 and the second insulating grid 4 respectively using metal oxide, nitride or fluoride as the material;

[0066] S4, after the first insulating gate 3 and the second insulating gate 4 are prepared, they enclose a deposition area, the bottom of which is the transparent conductive block 23, and then the first transmission layer 64, the perovskite absorption layer 65 and the second transmission layer 66 are prepared in sequence in the deposition area by coating or deposition, and after the preparation is completed, 60 sub-cells 63 can be obtained;

[0067] At this time, every five sub-batteries 63 are connected in parallel through a transparent conductive block 23 to form a sub-battery unit 62, and a total of 12 sub-battery units 62 can be formed; in the second direction, the sub-battery units 62 are isolated by the first insulating grid 3 arranged in the first spacing groove 21;

[0068] S5, continue to prepare the electrical connection grid 5 on each transparent conductive block 23 (i.e., print silver paste on the surface of the transparent conductive block 23), and perform annealing to obtain the electrical connection grid 5;

[0069] S6, preparing a back electrode 7 on each sub-cell 63 by evaporation or deposition, and making the back electrode 7 form electrical contact with the electrical connection grid 5;

[0070] At this time, in the first direction, three sub-battery units 62 are connected in series through the electrical connection grid 5 to form a battery group 61, and a total of four battery groups 61 can be formed, that is, the back electrode 7 in each sub-battery unit 62 extends to the electrical connection grid 5 of the adjacent sub-battery unit 62 to form a series connection;

[0071] S7, welding the bus bar 8, and connecting the four battery groups 61 in parallel through the bus bar 8 to form a perovskite battery layer 6;

[0072] S8, stacking the encapsulation layer and the back plate on the back electrode 7 in sequence, and then entering into a laminator for lamination to obtain a perovskite battery assembly.

[0073] Example 3

[0074] The difference between Example 3 and Example 1 is that the perovskite battery layer 6 in Example 3 is formed by four battery groups 61 connected in series through a bus bar 8, such as Figure 5 As shown, the rest is the same as Example 1.

[0075] In the manufacturing process of conventional perovskite battery components, three laser scribings, P1, P2 and P3, are generally required. The P1 laser scribing is consistent with the P1 laser scribing in Example 2. The P2 laser scribing in the conventional manufacturing process is performed after the first transmission layer 64, the perovskite absorption layer 65 and the second transmission layer 66 are prepared, and is used to cut the first transmission layer 64, the perovskite absorption layer 65 and the second transmission layer 66. The P3 laser scribing is performed after the back electrode 7 is prepared, and is used to simultaneously cut the back electrode 7, the first transmission layer 64, the perovskite absorption layer 65 and the second transmission layer 66 (the directions of the P2 laser scribing and the P3 laser scribing are perpendicular). Since the P2 and P3 laser scribings are required in the manufacturing process of conventional perovskite battery components, and the laser scribing will damage the perovskite battery layer, it will lead to problems such as attenuation of electrical performance, decreased stability and shortened service life of the perovskite battery components.

[0076] The present invention optimizes the structure of the perovskite battery module, and the first insulating gate 3 and the second insulating gate 4 play the same role as the P2 and P3 laser scribing. Therefore, the battery module of the present invention does not need to use the P2 and P3 laser scribing process. It not only avoids the thermal effects caused by the P2 and P3 laser scribing that damage the perovskite battery layer and cause performance degradation, reduced stability and shortened service life, but also reduces the cost of laser scribing, thereby reducing the production cost of the battery module.

[0077] The above preferred embodiments of the present invention are only used to explain the present invention, and are not used to limit the present invention. Any obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
