6 FAQs about [Space Debris Solar Cells]

How does space debris impact a solar cell?

The discharge can make noticeable mechanical damage on the surface of solar cells. Space debris impact with spacecraft at an average velocity of ~10 km/s and thus induce high-density plasma [ 1, 2 ]. The characters of high-velocity impact inducing plasma have been studied in Lee's experiment .

How does space-debris impact a solar array?

Does space debris impact a solar array?

Thus, the solar array with a larger area and higher voltage is more sensitive to space debris impact inducing discharge. Mengu Cho's work suggested that the impact of space debris larger than 1 mm can induce sustain arc and secondary discharge on high voltage solar array , , .

Can solar arrays be impacted by meteoroids or space debris?

As solar arrays have the largest exposed to the space area, their probability to be impacted by meteoroids or space debris is high. From the inspection of the retrieved HST array, for instance, the whole wing suffered between 5000 and 6000 micrometeoroid impacts in its 4-year life.

What happens when a solar cell is discharged?

During the discharge, the voltage between the solar cells decreases. The voltages after different discharges vary from −36 V to −17.6 V, which indicates that the minimum voltage for maintaining the discharge is 17.6 V. When the voltage difference between the solar cells is 36 V, no discharge is triggered.

How are solar cells insulated?

Between the solar cells and solar panel, a layer of polyimide film is pasted to insulate the solar cell electrodes and conductive substrate. The cover glasses that are used to provide protection for the cells against radiation and microparticles impact damage are made usually of cerium-doped glass 0.01 cm thick.
