PHYSICAL MECHANISM OF SOLAR CELL SHUNTING UNDER HIGH VELOCITY IMPACT OF SOLID PARTICLES

LETIN, V. A. / NADIRADZE, A. B. / NOVIKOV, L. S.

Abstract The mechanism of spacecraft solar array (SA) degradation caused by shunting of individual elements under impact of high-velocity solid particles has been analyzed. It was shown that the shunting effect appears as a result of irreversible structural changes in the semiconductor structure and it may be observed at an impact of rather large (over 50–100 μm), high-velocity (over 5–7 km·s–1) particles. A shunting model is presented, and critical impact parameters at which the effect manifests itself are identified.
