Abstract :
Attempts at Teflon bonding have always failed due to the mismatch of thermal coefficients of expansion. With the advent of the Pilkington CMZ and CMG coverglasses where the coefficients have been exactly matched to the solar cell material, the bonding process has been developed so that the advantages and disadvantages of Teflon bonding may be evaluated for use in the space environment. One important advantage is that Teflon lends incorporation of a device which limits the build up of electrical potential on the coverglass. Concepts for ESD protection and automated production assembly processes are given along with flight test results and environmental test programmes
