AI Technical Summary
Technical Problem
Due to the presence of gaps around the cell modules, incident light cannot be effectively absorbed, and the intensity of glaze plating on the back plate in the prior art is not high.
Method used
By providing a first reflective structure on the periphery of the three edges of the cell, and hot melting or softening on the carrier film to fix the reflective structure, a coated cell is formed, and a photovoltaic cell string and an array are then constructed.
Benefits of technology
Effectively utilize incident light to increase power generation power, avoid the problem of reducing strength caused by glaze plating on the back plate, and solve the possible offset and parallel series problems of battery strings during lamination.

Abstract
The invention provides a preparation method of a photovoltaic cell string, a preparation method of a cell string array and a cell module, relates to the technical field of photovoltaics, and aims to solve the technical problem that the strength of a cell module with a glazed backboard is not high when light rays among pieces are utilized. The method comprises the following steps: providing a battery piece, two bearing films and a first reflective structure; placing a first welding strip, a battery piece and a first reflective structure on a bearing film; wherein the battery piece and the first reflective structure are both located above the first welding strip, and the first reflective structure surrounds the periphery of three edges of the battery piece; the orthographic projections of the battery piece and the first reflective structure on the surface of the bearing film are located in the surface of the bearing film or coincide with the surface of the bearing film; sequentially placing a second welding strip and another bearing film above the battery piece and the first light reflecting structure to form an assembly; heating the assembly to form a film-coated battery piece; and repeatedly executing the target operation until the plurality of film-coated battery pieces are electrically connected to form a target battery string. The battery assembly prepared by the method is high in strength.
