Design and Implementation of an Auto Bonding Manufacturing Process for Space Solar Cells

摘要

This article presents a new manufacturing process of bonding anti-irradiation cover glasses to silicon solar cells with silicone adhesive. Due to the disadvantages of traditional manual operation, a new manufacturing process was designed considering the characteristics of solar cells, cover glasses, and silicone adhesive, and was complemented by an automatic system based on an industrial robot. Experiments indicated that the new approach could ensure the thickness of adhesive layer among 100–150 μm and effectively restrain the creation of air bubbles. The automatic system was tested to have high efficiency and reliability and it was going to make volume-produce.
