“…It has been suggested that the cause of radiation-induced loss is the creation of oxygen vacancies and the reduction of SiO 2 to SiO x , which absorbs UV wavelengths [12]. In another investigation, contamination with UVabsorbing species that were created in the radiation chamber was supported by the restoration of transmission after cleaning the sample [13]. To test the contamination hypothesis for our samples, we scanned, cleaned, and rescanned the samples five years after the proton exposures.…”

“…Another work involving 60 keV protons concluded through modeling that the effects observed could be explained by the creation of SiO from SiO 2 by oxygen atom displacement and vacancy creation in the ∼600 nm limit of penetration depth [12]. A recent paper described the effects of a contaminant layer reacted by solar UV on mirror coatings on MISSE-7 [13,14].…”

“…On ISS in LEO, AR and ESD coatings on solar cell covers are continually exposed to solar UV, electron and proton radiation, temperature extremes, and atomic oxygen. Table 1 lists the radiation concentrations modeled for various orbits and includes atomic oxygen and UV exposure experienced during the MISSE-7 mission exposure [13].…”

Specific coating processes and materials were investigated in the quest to develop multilayer coatings with greater tolerance to space radiation exposure. Ultraviolet reflection (UVR) and wide-band antireflection (AR) multilayer coatings were deposited on solar cell covers and test substrates and subsequently exposed to simulated space environments and also flown on the Materials International Space Station Experiment-7 (MISSE-7) to determine their space environment stability. Functional solar cells integrated with these coatings underwent simulated UV and MISSE-7 low earth orbit flight exposure. The effects of UV, proton, and atomic oxygen exposure on coatings and on assembled solar cells as related to the implemented deposition processes and material compositions were small. The UVR/AR coatings protected flexible polymer substrate materials that are intended for future flexible multijunction cell arrays to be deployed from rolls. Progress was made toward developing stable and protective coatings for extended space-mission applications. Test results are presented.

Recent growth in space systems has seen increasing capabilities packed into smaller and lighter Earth observation and deep space mission spacecraft. Phase-change materials (PCMs) are nonvolatile, reconfigurable, fast-switching, and have recently shown a high degree of space radiation tolerance, thereby making them an attractive materials platform for spaceborne photonics applications. They promise robust, lightweight, and energy-efficient reconfigurable optical systems whose functions can be dynamically defined on-demand and on-orbit to deliver enhanced science or mission support in harsh environments on lean power budgets. This comment aims to discuss the recent advances in rapidly growing PCM research and its potential to transition from conventional terrestrial optoelectronics materials platforms to versatile spaceborne photonic materials platforms for current and next-generation space and science missions. Materials International Space Station Experiment-14 (MISSE-14) mission-flown PCMs outside of the International Space Station (ISS) and key results and NASA examples are highlighted to provide strong evidence of the applicability of spaceborne photonics.
