TL;DR: In this article, a hexagonal hexagonal grating structure placed on the back of a thin (86 nm) GaAs cell was used to address the high transmission loss through such thin absorber layers, and the results of external quantum efficiency and light current-voltage measurements of thin devices without light-trapping features were found to be up to double that of the cells without lighttrapping.

Radiation effects in ultra-thin GaAs solar cells
TL;DR: In this article , the authors used time-resolved cathodoluminescence to map the introduction of radiation-induced defects with increasing proton fluence and characterize a decrease in carrier lifetime.

TL;DR: In this article, the first iteration of ultra-thin 80 nm absorber layer devices patterned by Displacement Talbot Lithography has shown promising electrical and optical performance, but their performance is limited due to their high levels of radiation.

- 14 Jun 2020
TL;DR: In this article, GaAs solar cells with an 80 nm active layer were designed, fabricated and tested under 68 MeV proton irradiation, and the results of electrical characterisation before and after proton beam exposure at two different fluences showed their tolerance to these harsh conditions.

TL;DR: In this article, the impact of high energy proton radiation, as would be encountered in highly eccentric and Europa orbits, on ultra-thin GaAs solar cells was studied, where cells were irradiated with 68 MeV protons at fluences of 2 × 1012 cm−2 and 1 × 1013cm−2.
