Embodiment 1

[0021] An assembly for optimizing the internal circuit of the present invention includes encapsulating glass 1, EVA2, battery sheet 3, EVA2, and backplane 4 from top to bottom, wherein the battery sheets 3 are connected in series through welding ribbons 7, and each welding ribbon 7. Connect the front of one cell 3 and the back of the next cell 3 in turn. The welding ribbon 7 on the front of the battery 3 is from the starting point 5 of the front welding ribbon to the end point 6 of the front welding ribbon. The width of the welding ribbon 7 gradually becomes wider; the battery sheet 3 The ribbon 7 on the back is from the starting point 8 of the ribbon on the back to the end point 9 of the ribbon on the back, and the width of the ribbon 7 gradually becomes wider. The position of the edge of sheet 3.

[0022] The width of the welding ribbon 7 between two adjacent battery sheets 3 connected in series remains unchanged.

[0023] The size of the module is 1640*992mm, the size of t...

Abstract

The invention discloses an assembly whose inner circuit is optimized, which, from top to bottom, sequentially comprises packaging glass, EVA, cells, EVA and a back plate, wherein the cells are serially connected via welding ribbons; each welding ribbon is sequentially connected onto the front surface of one cell and the back surface of the next cell; and from the welding ribbon starting point to the front-surface welding ribbon ending point on each cell, the welding ribbon becomes wider or thicker gradually. The inner circuit is optimized, the current bearing ability of the assembly is improved, the inner loss of the assembly is reduced, a narrow welding ribbon part exists, the shading area of the assembly is reduced, and power output of the assembly is improved from the electrical aspect and from the optical aspect.

Description

technical field [0001] The invention relates to the technical field of solar battery components, in particular to a component for optimizing internal circuits. Background technique [0002] As a new energy source, photovoltaic is playing an increasingly important role in the energy field, and in the long run, it is also an excellent choice to replace traditional energy sources. At present, photovoltaic products are pursuing high conversion efficiency, that is, generating as much electricity as possible under the same area. The operating current of a 156*156mm crystalline silicon solar cell is about 8A, and the crystalline silicon solar cell modules are generally connected in series. Due to its higher current value, losses on the internal circuitry of the component are also higher. How to optimize the internal circuit of the battery pack to reduce loss is a problem to be solved in the present invention. Contents of the invention [0003] The object of the present inventi...
