Research Institution
The USAF is seeking to replace UV-susceptible adhesive that bonds the solar cell to a cover glass for enhancing conversion efficiency and to improve durability. Adhesives used for space solar modules need to meet many critical requirements including adhesion strength, optical transparency, thermal stability, and resistance against a broad range of radiation present in space environments including UV. In addition, system compatibility requirements need to be met with regards to optical matching with adjacent layers. With these critical requirements, the choices are limited and the technical challenges to be met for processing and performance at affordable costs are significant. This Phase I effort will explore an entirely new adhesive concept based on an extremely thin, highly transparent, inorganic adhesive that looks promising to meet many of the requirements. The material exhibits excellent thermal and chemical stability/inertness which is essential for this application while offering an easy to apply and rapid processing method for transitioning the technology to production. Phase I will be conducted in close collaboration with an industrial partner engaged in developing and manufacturing solar modules for space and other applications. Phase I work plan will include development of adhesive and testing of primary property requirements.
