DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

As shown in Figures 4 and 5, the present invention provides a solar panel based on an artistic pattern, including a plurality of solar cells arranged to form a panel, a pattern is provided on the front of the panel, a part of the pattern is distributed on each solar cell, and all the arranged solar cells fully display the designed pattern. The solar cells are connected to a junction box.

As shown in FIG1 , in this embodiment, a grid structure is formed on the solar cell, the grid structure includes transverse fine grid lines and longitudinal fine grid lines, and the longitudinal fine grid lines are intermittently connected to the transverse fine grid lines. The upper and lower ends of the solar cell are respectively provided with main grid lines for welding.

The present invention also provides a method for designing a solar panel based on an artistic pattern, comprising the following steps:

Step 1: Design a grid-structured front electrode screen for a single solar cell. As shown in Figure 1, the screen uses 90 to 110 horizontal fine grid lines, 20 to 40 vertical fine grid lines that intermittently connect the horizontal fine grid lines, and the horizontal fine grid lines or/and the vertical fine grid lines have a width of 30um to 45um. In order to derive current, five main grid lines with a length of 4mm to 9mm and a width of 0.5mm to 0.8mm are left at the upper and lower ends of the solar cell to facilitate component welding.

Step 2: Arrange the screen designed in step 1 according to the size of the component board, set the distribution of solar cells and the spacing between the cells. As shown in Figure 2, in this embodiment, the panels are arranged into 6*10 pieces according to the specifications of the component board, and the spacing between the solar cells is set. As shown in Figure 3, if the solar cells are 3mm apart from each other, and the total distance between the left and right sides of the screen and the solar cells is 1.95mm, then the left and right gap of the screen is 4.95mm; similarly, if the solar cells are 1.5mm apart from top to bottom, and the total distance between the top and bottom of the screen and the solar cells is 1.95mm, then the top and bottom gap of the screen is 3.45mm.

Step 3: Place the pattern to be designed under the solar cells arranged in step 2, as shown in Figure 4. Before placement, pre-process the pattern to be designed, set the pattern background color to black, and then insert the pattern under the arranged solar cells, adjust the pattern size and position so that the details of the pattern are located inside the solar cells.

As shown in FIG5 , the intersection of the thin grid lines of the solar cell and the pattern outline lines is thickened. The original line width of the thin grid lines is 30um to 45um, and the line width after thickening is 80um to 120um. After processing, the whole board pattern is formed.

Step 4: The whole panel pattern of step 3 is divided into individual solar cell units to form a solar cell positive electrode screen with a pattern structure, as shown in FIG6 and FIG7.

Step 5: During the production of solar cells, the positive electrode screen of the solar cell with a pattern structure is screen-printed. After printing, the back of the solar cell is numbered according to the position of the single pattern in the whole board pattern.

Step 6: Arrange the printed solar cells, specifically, arrange them in order according to the numbers of the solar cells, and then form a solar panel with an artistic pattern after welding, lamination, and adding a junction box.

The present invention adds artistic pattern forms to the traditional solar cell front electrode design process, and forms a complete artistic pattern by splicing the patterns on the cells into a component panel. Under the requirement of ensuring the power generation characteristics of the solar cell component panel, different artistic patterns can be designed according to different application scenarios of the solar cell component panel, which is more in line with the needs of modern construction and decoration. The pattern can be changed according to people's needs and has good flexibility. The designed pattern is formed on the electrode. After being packaged by the component, it is not affected by the external environmental temperature and humidity, and the pattern is durable.

The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
