Half-slice-laminated solar assembly and preparation method thereof

Abstract

The invention provides a half-slice-laminated solar assembly and a preparation method thereof. The method comprises the following steps: S1) slicing a battery piece to obtained a sliced battery, and carrying out insulation treatment on the cutting edge by utilizing laser; S2) placing a solder strip on the sliced battery and welding the sliced battery and the solder strip together; S3) repeating the process of the S2) to obtain a plurality of sliced batteries having solder strips, and arranging and welding the plurality of sliced batteries in an overlapping manner in sequence through the solderstrips to obtain a battery string; S4) repeating the step S3) to obtain a plurality of battery strings, and arranging the plurality of battery strings according to the assembly layout to obtain a battery string assembly; S5) laying a first adhesive film layer on tempered glass, and placing the battery string assembly on the upper surface of the first adhesive film layer; S6) laying a second adhesive film layer on the upper surface of the battery string assembly, and then, placing a backboard material layer on the second adhesive film layer to obtain a laminated assembly; and S7) carrying outlamination processing on the laminated assembly, and then, carrying out package processing. The method has the advantages of simple process and firm and stable welding and the like.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic modules, in particular to a half-chip laminated solar module and a preparation method thereof. Background technique [0002] A solar module is a semiconductor device that converts solar energy into electrical energy. At present, the mainstream products in the photovoltaic industry are conventional modules, which have the advantages of mature product process routes and simple process flows, but they often lead to rigid and conservative sizes, and the designs are often stereotyped and rigid, unable to break the existing size constraints and design specifications. The effective area utilization rate and conversion rate of the components manufactured by the prior art process are relatively low, and further improvement is needed. Contents of the invention [0003] The object of the present invention is to address the above problems and provide a half-sheet laminated solar module that can increa...
