Solar cell coverglasses for satellites in the intermediate Earth orbit

Abstract

Satellites in an earth orbit where high levels of radiation are experienced require greater protection for their solar cell arrays than is normal. This may be provided by the use of thicker coverglasses to minimise solar cell degradation. This paper describes the development by Pilkingtons of a new glass CMO, which has a high transmission in the visible spectrum ,is radiation stable to high fluences, incorporates a UV 'cut-off ' filter and is capable of being manufactured economically in large volume. It has a high emissivity and is durable. The results of an evaluation are given and compared with high purity fused silica.

Space environmental testing of flexible coverglass alternatives based on siloxanes

“…In these glasses cerium absorbs the high energy UV photons (wavelengths shorter than 350 nm), thereby protecting underlying layers. At the same time it prevents damage to the glass into which it is incorporated [17]. A similar effect was expected for the CeeMBS samples, but the degradation measured is larger than for MBS samples (cf.…”

Flexible shielding layers for solar cells in space applications

“…This gives rise to absorption bands, since the trapped electrons form color centers ultimately leading to reduced transmission in the glass. The damage is prevented by Ce(IV) ions absorbing the displaced electrons, while Ce(III) ions eliminate the holes by electron donation …”

Are Metal Halide Perovskite Solar Cells Ready for Space Applications?

“…Commercially available quartz glass or cesium-doped glass substrate (CMX, CMG, and CMO glass) also known as superstrate has excellent radiation stability and low absorption. 84 They can be used for PSCs for space applications. Likewise, the materials for metal electrodes like Au, Ag, or Al have been widely used for space PVs without concern regarding their radiation stability.…”

“…In most of the reports testing radiation stability of PSCs, darkening of the conductive glass substrates is often observed, leading to reduced J sc . , This is ascribed to the collision of high-energy particles on soda lime glass, producing structural defects within the glass and forming new absorption bands.

They can be used for PSCs for space applications.…”
