Abstract

The invention discloses a lap joint method of cell strings, comprising the following steps: multiple cells which are horizontally arranged and have upward backs are sequentially arranged in the left-right direction; the cells are sucked up synchronously, then the cells are rotated by a certain angle, the rotation directions of the cells are that first side lines face upwards and second side linesface downwards, and the cells are inclined at a small angle; the distance between two adjacent cells is reduced, so that front edge electrodes are positioned right above the external sections of adjacent connecting pieces; and all the cells are synchronously placed on a certain plane, so that the front edge electrodes are pressed on the external sections of the connecting pieces located under thefront edge electrodes, and lap joint of the cell strings is completed. According to the invention, multiple cells can be synchronously in lap joint, and the lap joint efficiency of cell strings can beimproved.

Description

technical field

[0001] The application belongs to the field of solar photovoltaic cells, and in particular relates to a method for overlapping battery strings. Background technique

[0002] The battery string is an important module in the solar cell module. The battery string is composed of battery slices connected in series, and two adjacent battery slices in the battery string are connected in series through connectors, and the commonly used connectors are generally welding ribbons.

[0003] At present, the overlapping of battery strings is generally to cut off the welding ribbon piece by piece and overlap the battery pieces one by one. To the outer side of the battery piece, and then overlap the next battery piece on the small section of the welding ribbon, and repeat this until the whole battery string is overlapped. Obviously, the way of overlapping cells one by one is inefficient. Contents of the invention

[0004] The purpose of the present invention is to provid...
