Study on quality control in the bonding processing of space solar cell

The solar cell is widely used for space power. The characteristic of anti-irradiation is one of the important differences between ordinary solar cells and space solar cells. In order to ensure a space solar cell works reliably in the space environment, it is necessary to bond the anti-irradiation cover-glass to the space solar cell active surface using a kind of adhesive, and it is vital to have a reasonable coating thickness. Combining robotics and adhesive-coating technology, this paper gives an automatic bonding system for space solar cells, which can precisely control the coating thickness and realize bonding automation in non-vacuum conditions. Moreover, on the basis of the theory of non-Newtonian fluids, the paper presents a model for this system and deduces the formula for the coating thickness of space solar cells. Experiments have been performed to validate this model.
