Abstract

The invention discloses a method for manufacturing an inner series cell photovoltaic module and a packaging structure. The inner series cell photovoltaic module includes multiple rows of battery sheet groups and packaging assemblies arranged in a row, and each row of the battery sheet groups includes a plurality of cells. The battery sheet includes a plurality of battery sections connected in series along the row direction and has a first electrode and a second electrode, and any two adjacent battery sheets in the row direction are connected by connecting the first electrode and the The welding strips of the second electrode are connected in series, the multiple rows of battery slice groups are connected in parallel through the first bus bar and the second bus bar, and the multiple rows of battery slice groups are all packaged in the package assembly. The internal series cell photovoltaic module provided by the present invention has the advantages of no need for cutting and processing of the cells to avoid cell damage, high CTM rate, low internal loss, convenient manufacture, and the like.

Description

technical field [0001] The invention relates to the technical field of packaging of heterojunction battery components, in particular to a manufacturing method of an inner-tandem cell photovoltaic module and a packaging structure. Background technique [0002] Photovoltaic module packaging methods are mainly divided into three types, full-chip, half-chip, and shingled modules. Among them, full-chip modules have been gradually marginalized due to reasons such as CTM rate and module anti-local shading ability. Half-cut and shingled components need to involve cell cutting, and shingled components need to use conductive glue and related patent restrictions make it difficult to control costs. Due to the unique structure of heterojunction cells, cutting damage control of heterojunction cells has always been a technical problem. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. F...
