4 FAQs about High-Temperature Resistant Photovoltaic Containers for Research Stations

What is a high-intensity solar array?

High-intensity solar array: A secondary solar array (Fig. 14.7) was then incorporated to power the mission at the high-intensity portion of the mission, operating inside 0.25 AU. Since at this distance the intensity was high, the secondary solar array could be much smaller. This power supply used high-efficiency triple-junction solar cells

Why do solar arrays need a high temperature range?

Extending the temperature range of operation for solar arrays is highly desirable for extending the range of operation of space missions to the near-Sun environment [5e7]; interestingly, high temperatures help prevent arcing of solar arrays .

Should a high-bandgap solar cell be used for high-temperature operation?

For high-temperature operation, as discussed before, a high-bandgap solar cell ma-terial would be preferred, but the blue-deficient spectrum puts a limit on the availability of short-wavelength photons.

Why do photovoltaic cells operate at a higher intensity?

Since the fractional loss of Voc with temperature de-creases in magnitude as bandgap increases , photovoltaic cells from wide-bandgap materials can operate at higher intensity (so higher temperatures) than cells from narrow-bandgap materials [5e7].
