Abstract

The invention provides a solar cell module preparation method and a solar cell module. The method comprises the steps: laying a lower-layer adhesive film above a backboard; laying battery sheets and conductive strips on the lower-layer adhesive film, wherein the two adjacent battery sheets are connected in series through the conductive strip; sequentially laying an upper-layer adhesive film and acover plate above the battery sheets from bottom to top to form a battery string assembly; preheating the battery string assembly so as to pre-bond the conductive strip on the back surface of the battery sheet and the lower-layer adhesive film and pre-bond the conductive strip on the front surface of the battery sheet and the upper-layer adhesive film; and carrying out lamination curing molding onthe cell string assembly to form the solar cell assembly. According to the invention, by using a low-temperature preheating mode, the pre-fixation of the conductive strips, the upper-layer adhesive film and the lower-layer adhesive film is realized, the use of an existing welding strip is canceled, and a high-temperature welding process between the welding strip and the battery sheet is also canceled, so that the forming process steps of the solar battery assembly are simplified, the forming difficulty is reduced, and the production cost is saved.

Description

technical field [0001] The present application relates to the technical field of photovoltaic power generation, and in particular to a method for preparing a solar cell assembly and the solar cell assembly. Background technique [0002] As an environmentally friendly energy source, solar cells are widely used in various fields. In the preparation process of existing solar cell modules, before entering the lamination equipment, it is generally necessary to use ribbons to weld multiple solar cells into battery strings at a high temperature of 200°C to 400°C, and the high-temperature welding of ribbons requires special welding equipment to achieve. Among them, the purchase of welding equipment will lead to an increase in production costs, and also increase the complexity of the solar cell module preparation process. Contents of the invention [0003] The purpose of this application is to provide a method for preparing a solar cell module and the solar cell module, so as to ...
