The principal objective of this report is to highlight new materials, state-of-the-art preparation techniques and innovative designs which are currently available to improve the efficiency of solar cell power systems aboard spacecraft. A significant improvement in energy conversion efficiency can usually be translated into a lenghtier and more cost-effective mission. Several important topics were omitted from the above discussion. The first is the effect of the Van Allen radiation on solar cells, adhesives, and coverslips. The second is the influence that levels of light intensity have on the energy conversion process in space. This promises to become an important issue as designers of space power systems begin to exploit concentrator technology for high power GaAs solar arrays. It is well-known that temperature effects on solar cell performance are modified by radiation and light intensity. A third topic that should be investigated in more detail is the effect of temperature cycling which can play an important role on satellite missions that have lengthy periods of eclipse. The space power designer should always be alert to new developments in materials science that can be adapted to improve solar cell systems aboard spacecraft.
