Embodiment 1

[0029] Embodiment 1: a kind of novel solar battery slice of present embodiment 1, as figure 2 As shown, it includes the substrate, the front electrode structure and the back electrode structure designed on the front and back of the substrate. The main grid line 1 and the auxiliary grid line 2 are connected to each other to form the front electrode structure of the cell. The line width of the main grid line is 1.5mm, and the line width of the auxiliary grid line is 0.05mm; The partition 3 is designed on the sub-grid lines in between, the partition is located in the middle of the sub-grid line, and the partition width is 1mm. The partition divides the sub-grid line into two symmetrical sections. The main grid line is connected, and the partition on the auxiliary grid line forms a partition line 4 parallel to the main grid line. The entire front of the cell is divided into three independent power generation areas by the partition line, and each power generation area contains onl...

Embodiment 2

[0031] Embodiment 2: a kind of novel solar battery sheet of present embodiment 2, as image 3 As shown, it includes the substrate, the front electrode structure and the back electrode structure designed on the front and back of the substrate. An auxiliary grid line, and the battery sheet is square. The other parts of this embodiment 2 are similar to the corresponding parts of the embodiment 1, and will not be repeated here.

Abstract

The invention discloses a novel solar energy battery piece which comprises a base plate, a front electrode structure arranged on the front of the base plate and a back electrode structure arranged on the back of the base plate. The front electrode structure comprises a plurality of parallel main grid lines printed on the front of the base plate and multiple vice grid lines vertically connected with the main grid lines. Partition lines are arranged on the vice grid lines between every two adjacent main grid lines in a partition mode. A batter piece which is prone to failure or poor performance as a whole due to partial cutting-out or damage in the prior art is divided into multiple isolated power generating zones. When an abnormal situation happens to one zone, the other zones can still work normally so that affection of partial abnormality on the whole battery is obviously reduced, stability and safety of the solar battery piece are improved, meanwhile, different isolated power generating zones can be respectively used and use flexibility and range of the battery piece are enhanced.

Description

[0001] technical field [0002] The invention relates to a solar cell, in particular to a novel solar cell capable of improving the stability of the solar cell and preventing the overall failure of the cell. [0003] Background technique [0004] Crystalline silicon solar cells mainly include single crystal crystalline silicon solar cells and polycrystalline crystalline silicon solar cells [0005] These two types of solar cells are semiconductor devices that can directly convert light energy into electrical energy made on the corresponding silicon wafer materials. There is no emission of other process conversion products during the photoelectric conversion process, so they are considered to be It is the most promising new type of green energy to solve human's future energy demand and reduce environmental pollution. [0006] The electricity generated by crystalline silicon solar cells needs to be collected by the positive and negative metal electrodes attached to its surfa...
