Abstract

The invention discloses a solar energy cell series structure. The solar energy cell series structure includes two adjacent cells, wherein the two cells are connected in series through a conductive connection member, the conductive connection member extends from a front side of one of the cells to a back side of the other cell, edge lines of opposite ends of the two cells are arranged up and down,and the edge lines of the opposite ends of the two cells are aligned up and down. The solar energy cell series structure is advantaged in that the edge lines of the opposite ends of the two adjacent cells are aligned up and down, density of the cells can be maximized in the horizontal direction, the edge lines of the opposite ends of the adjacent two cells are aligned up and down, that is, the adjacent two cells are not blocked from each other, a problem that one of the adjacent two cells blocks the other cell due to use of the imbricate technology can be avoided, and waste of the cell area isavoided.

Description

technical field [0001] The invention relates to a series structure of solar cells. Background technique [0002] Solar cell modules (also called solar panels, photovoltaic modules) are the core part of the solar power generation system. The solar battery module includes a battery string, and the battery string is composed of a plurality of solar battery slices laid in series in sequence. There are two main connection methods of existing battery strings: tiling and shingling. [0003] In the tiling method, there is a certain distance between two adjacent cells in the horizontal direction (with a conductive connector in between), so the density of cell laying is not maximized. [0004] In the shingling method, one of the two adjacent cells will block the other cell, which will cause a waste of cell area. Contents of the invention [0005] In order to solve the defects in the prior art, the present invention provides a series structure of solar cells, which includes two ad...
