Study on Quality Control in the Bonding Processing of Space Solar Cell

摘要

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