III-V solar battery packaging part and manufacturing method thereof

Abstract

The invention relates to an III-V solar battery packaging part and a manufacturing method thereof. The manufacturing method of the III-V solar battery packaging part comprises the following steps of: providing a solar battery with a first side and a second side which are opposite; forming a first insulating layer on the first side of the solar battery and a second insulating layer on the second side of the solar battery; forming a light-transmitting layer on the first insulating layer and a protecting layer on the second insulating layer; and pressing the light-transmitting layer and the protecting layer to enable the first insulating layer to be bonded with the light-transmitting layer and the solar battery and the second insulating layer to be bonded with the protecting layer and the solar battery, thus, the flexible solar battery packaging part is formed by utilizing the flexibility of the insulating layers, the light-transmitting layer and the protecting layer. The invention also provides a solar battery packaging part.

Description

technical field [0001] The invention relates to a battery package and a method for making the same, in particular to a solar battery package and a method for making the same. Background technique [0002] At present, the purpose of packaging solar cells is mainly to protect the solar cells and the connecting wires, so that the cells and wires are not damaged by moisture in the air, erosion of other compounds, and dust, so as to improve conversion efficiency and prolong the life of the package. service life. The electricity generation of solar cells is to use light to hit the active surface of the battery, so that free electrons are separated to generate current; among them, materials with high light transmittance are easy to allow light to pass through, so the light transmittance of packaging materials is extremely important. [0003] figure 1 is a schematic diagram of a known solar cell package 1 . The manufacturing method is to firstly fix the solar cells 10 on the subs...

AI Technical Summary

Problems solved by technology

[0004] However, it is known that the solar cell package 1 has a substrate 11, which makes it too heavy and too thick, and cannot be bent or has a poor curvature, so that it cannot meet the needs of miniaturization, and can only be used as a flat product. and cannot be used for curved products

[0005] Furthermore, after long-term use of the epoxy resin-based encapsulation material 12, its surface tends to turn yellow and darken, which affects the light transmittance, resulting in poor conversion efficiency of the solar cell 10.
