Encapsulating process of solar cell module

Abstract

The invention relates to an encapsulating process of a solar cell module, solving the technical problem that the solar cell module is prone to crush because of hard extrusion in the encapsulating process. The invention adopts the technical scheme that the encapsulating process comprises the following steps of: carrying out composite treatment on a substrate, an insulation photographic film and anencapsulating substrate which are prepared for finishing a solar cell layer to form the solar cell module; then, forming and treating the solar cell module, installing a junction box, realizing the external environmental atmosphere of the solar cell module by the aid of a high-pressure kettle in the forming and treating processes, realizing the internal environmental atmosphere of the solar cell module by the aid of a matched vacuumizing system; and further setting the process conditions by the aid of a temperature and pressure intensity control system, wherein the solar cell module synchronously finishes the heating, pressing and forming processes in the kettle. The invention has the advantages that the problem that the cell module is prone to cause a high chipping rate because of hard extrusion is solved, the cell module is encapsulated at scale, and the encapsulating efficiency is increased.

Description

technical field [0001] The invention relates to a packaging process for solar cell components, which is applied to the field of solar cell panel manufacturing, in particular to a package that can effectively avoid hard damage to solar cell panels caused by rolling pressure and reduce the fragmentation rate of solar cells during the packaging process craft. Background technique [0002] With the continuous development of human beings, energy consumption is increasing, while the total amount of traditional energy is decreasing. Solar energy is most likely to replace traditional energy sources, and when using solar cells to generate electricity, the packaging process directly affects the battery life. [0003] Taking amorphous silicon thin-film solar cells as an example, the preparation process of solar cells includes sequentially preparing a conductive film layer, a photovoltaic absorber layer, and a back electrode layer on a cleaned substrate, and then cutting the back elect...
