Abstract
The application discloses a back contact lamination solar cell string and a manufacturing method thereof, and a lamination solar cell module. The back contact lamination solar cell string comprises aplurality of mutually series-connected back contact solar cell pieces which are stacked in order, the positive pole and the negative pole of each back contact solar cell piece are both arranged at theback surface of the back contact solar cell piece, the edges of one sides of the back contact solar cell pieces are provided with a plurality of through holes, every two adjacent back contact solar cell pieces have an overlapping region, the through holes of the back contact solar cell pieces located at the lower portion are located at the overlapping regions, through electrodes are formed in thethrough holes, every two adjacent back contact solar cell pieces are connected in series through the through electrodes, the electrodes of the back contact solar cell pieces are electrically connected with the through electrodes, and a conductive wire is at least partially inlaid in a thermoplastic polymer film. The arrangement of the plurality of back contact solar cell pieces is achieved.
Description
technical field [0001] The present invention generally relates to the field of photovoltaics, specifically to the field of back-contact solar cell components, and in particular to a back-contact stacked solar cell string, a manufacturing method, and a stacked solar cell component. Background technique [0002] Stacked module (also called shingled module) technology is a new type of module design scheme. The battery sheets are superimposed and arranged, and connected into a battery string through conductive glue, solder paste and other materials, and then after series-parallel typesetting, the layers Pressed into components. By improving the interconnection structure design of the cells, more cells can be arranged in a limited area, improving the utilization of the space area and the power generation of the components. [0003] At present, back-contact solar cells (such as IBC, MWT, and EWT solar cells) have received widespread attention. Since there are no busbars on the fr...
