Example Embodiment
[0064](Example 1)
[0065]The all-black solar photovoltaic module of this embodiment includes a light-transmitting layer, a first EVA adhesive film layer, a cell array, a second EVA adhesive film layer, and a back sheet in order from top to bottom. seeFigure 2 to Figure 4The square battery array includes a plurality of battery slices 1 arranged in a matrix, and each column of battery slices 1 is connected in sequence to form a battery string by interconnecting strip welding tape 2. There are six battery strings in the battery array. A gap is provided between the two battery slices 1 in the middle of each battery string. The interconnecting strip welding strip 2 in the gap is connected by a first bus bar 3, and the first bus bar 3 is connected with a second bus bar 4 that is perpendicular to the first bus bar 3 in the horizontal direction and penetrates the back plate. The interconnection strips 2 at the ends of the battery string are connected by the third bus bar 5. In order to obtain...
Example Embodiment
[0077](Example 2)
[0078]This embodiment is basically the same as Embodiment 1, except that the angle between the end of the second bus bar 4 that is inclined to the back plate and the back plate is 14°.
Example Embodiment
[0079](Example 3)
[0080]This embodiment is basically the same as Embodiment 1, except that the angle between the end of the second bus bar 4 inclined to the back plate and the back plate is 16°.
