Preliminary results and implications for solar array design will be discussed, with application to direct-drive electric propulsion and space solar power.

The cells represent a mix of promising new technologies identified by the Air Force Research Laboratory (NFRL) under the CYGNUS Space Science Technology Experiment (SSTE-4) Program. Measurements of parasitic current loss, charging/dielectric breakdown of cover-slide coatings and arcing threshold tests are performed for each individual cell. These measurements are followed by a series of experiments designed to test for catastrophic arc failure mechanisms. A special type of power supply, called a solar array simulator (SAS) with adjustable voltage and current limits on the supply's output, is employed to bias two adjacent cells at a predetermined voltage and current. The bias voltage is incrementally ramped up until a sustained arc results. Sustained arcs are precursors to catastrophic arc failure were the arc current rises to a maximum value for long timescales (often ranging between 30 to 100 microsecond times). Normal arcs by comparison, are short lived events with a timescale between 10 and 30 microseconds). Sustained arcs lead to pyrol with extreme cell damage and have been shown to cause the loss of entire array strings in solar arrays. The collected data will be used to evaluate the suitability of thin-film photovoltaic technologies for future space operations
