Novel solar energy battery piece

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...
