Experiment Title: Investigation of Critical Surface Degradation Effects on Coating and Solar Cells Developed in Germany
Original Principal Investigator(s): Preuss, Dr. Ludwig - Invest. Role: Original, Preuss, Dr. Ludwig - Invest. Role: Present,
Experiment Description:Various coating developed in Germany (i.e., second-surface mirrors with interference filters with and without conductive layers, conductive layers on solar-cell covers, and selective absorber coatings) have been qualified by accelerated tests under simulated space environment conditions. Experiments with coatings and solar cells have shown, however, that the thermo-optical behavior can differ considerably when performed on the ground and in space because of the great difficulty in simulating the space environment. Thus, thermal control coatings, solar cells and micrometeoroid capture cells developed under government contract were flown on LDEF Experiment S1002 to investigate both the behavior of these components under space conditions and to collect micrometeoroids and debris.
