Preparation method of solar double glass module

Abstract

The invention discloses a method for manufacturing a solar double-glass assembly. The method includes the following steps that (1) a PVB adhesive film, a solar battery string, a PVB adhesive film and surface layer tempered glass are sequentially laid on bottom layer tempered glass, so that the solar double-glass assembly is formed; (2) whether hidden cracking pieces exist in solar battery pieces of the double-glass assembly in the first step is checked, and the hidden cracking pieces are removed; (3) the double-glass assembly is placed in a laminating machine under the -1 barometric pressure, the process is kept for 30-40 minutes, then an upper chamber of the laminating machine is placed at the pressure of -0.5 MPA, a lower chamber is placed at the pressure of -1 MPA, the process is kept for 20-30 minutes, afterwards, the temperature rises to be 140+ / -5 DEG C, and at the pressure of -0.5 MPA to -0.6 MPA, the process is kept for 20-30 minutes; (4) whether hidden cracking pieces exist in the solar battery pieces of the laminated double-glass assembly is checked, and the hidden cracking pieces are removed; (5) the double-glass assembly is fixed, the double-glass assembly is placed in an autoclave, and after a dehumidifier is used for dehumidifying, under the conditions of 20-150 DEG C and 0-1.3 MPA, the process is kept for 2-4 hours.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to a preparation method of a solar double-glass component used for a curtain wall. Background technique [0002] As an inexhaustible and inexhaustible green energy, solar energy has attracted widespread attention from the whole society in today's energy shortage. With the advancement of solar cell technology and the reduction of material costs, photovoltaic power generation technology has entered maturity, and solar photovoltaic products have gradually developed from special specialized uses to market-oriented consumer products, and their application range has expanded to various fields. Conventional solar modules are made through welding, laying, and lamination processes. The existing lamination process is to place the double-glass modules after laying in a laminator, and after a certain period of time under the set temperature and pressure Finish. For double-glass compone...

Problems solved by technology

For double-glass components used in glass curtain walls, the lamination time in the prior art generally takes more than 3 hours, and the performance indicators of the produced components can meet the requirements of curtain wall construction. This lamination method not only has low production efficiency, but also Moreover, since the starting temperature and the end point temperature are basically the same, the cell damage rate in the module is relatively high. At the same time, it is difficult to overcome the problems of water mark defects, air bubbles and cell displacement in the module.
