Abstract

The invention discloses a high-strength glass cover sheet for a solar cell circuit and a manufacturing method thereof. The high-strength glass cover sheet for a solar cell circuit comprises a glass cover sheet body, rough surfaces symmetrically arranged on the upper and lower surfaces of the glass cover sheet body and bright surfaces symmetrically arranged on the upper and lower surfaces of the glass cover sheet body. The surface roughness of the rough surface is greater than 10 mum; the surface roughness of the bright surface is less than 5 nm. The invention can improve the surface slow reflection, reduce the light transmittance, improve the surface roughness, and improve the interface connection strength with the connection structure through the local hairing. Local brightness can reducethe edge defects, reduce the edge stress concentration, achieve high stiffness, and maintain good performance in high temperature strengthening treatment. The invention can reduce the transmittance of the glass cover, increase the reflection, reduce the temperature of the solar cell circuit, improve the power generation performance of the solar cell space and prolong the life of the solar cell array.

Description

technical field [0001] The invention relates to the technical field of space solar battery arrays, in particular to a high-strength glass cover sheet for solar battery circuits and a manufacturing method thereof. Background technique [0002] A solar cell is a semiconductor device that uses the photovoltaic effect to directly convert light energy into electrical energy. When the aircraft is flying in space, it will be irradiated by high-energy particles or rays. The glass cover is encapsulated on the surface of the solar cell to protect the cell and reduce the damage to the solar cell from adverse radiation. There are two types of cover glass for semi-rigid solar cell circuits. One is the cover glass for surface protection, which mainly protects the solar cell, reduces adverse radiation damage, and prolongs its life in the space radiation environment; the other is the cover glass for surface protection. The main function of the solar cell is to protect the battery and conne...
