Abstract

The invention discloses a laminating method of a flexible solar assembly. The laminating method comprises aligning each layer of a material in a flexible solar assembly, placing the materials on a heating plate of a lower cavity of a laminating machine, simultaneously vacuuming the upper cavity and the lower cavity of the laminating machine, gradually increasing the pressure in the upper cavity ofthe laminating machine to the highest lamination pressure, keeping the differential pressure between the highest lamination pressure in the upper cavity of the laminating machine and the pressure inthe lower cavity less than 1 atm until all layers in the solar assembly are bonded, recovering the pressure in the upper cavity of the laminating machine to the initial laminating pressure in the step1, simultaneously, gradually increasing the pressure in the lower cavity of the laminating machine to 1 atm, and opening the lower cavity of the laminating machine to obtain the laminated solar assembly. In the initial stage of the laminating process, the pressure in the upper cavity of the laminating machine is gradually increased and the final lamination pressure is lower than 1 atm so that thepower generation performance and reliability of the photovoltaic cell are improved. The laminating method has simple processes and is easy to implement.

Description

technical field [0001] The invention relates to the field of solar component manufacturing, and more specifically, relates to a lamination method of a flexible solar component. Background technique [0002] Solar energy is an inexhaustible source of energy. It is estimated that the solar energy projected to the earth in one year is equivalent to the heat generated by 137 trillion tons of standard coal, which is about one-third of the current global More than 20,000 times the energy generated by utilizing various energy sources within a year. In my country, about 2 / 3 of the regions can make better use of solar energy resources, and solar power generation is not restricted by region, and the modularization of photovoltaic systems can be realized, installed in places close to power consumption or in areas far away from the grid, which can reduce power transmission and Reduce the cost of power distribution and increase the reliability of power supply facilities. At present, thi...
