Low-intensity–low-temperature stability assessment of perovskite solar cells operating on simulated Martian surface conditions

Abstract

Immigration to Mars, which is expected to be mainly powered by photovoltaics, is one of the greatest dreams of humanity. However, the extreme temperature difference and high-energy cosmic radiation on...

Low-intensity low-temperature analysis of perovskite solar cells for deep space applications

“…Our study confirms temperature-dependent and intensity-dependent trends from previous studies 2,33,44 utilizing two distinct cell architectures from ANU and Caelux, while also performing radiation tests on the same cells to contribute to the limited literature on low-energy proton radiation tests for PSCs. 4,16 With the resulting large data set of measured PSC efficiencies, we predict how the ANU PSCs would perform relative to SOA cells in the context of a space mission to Jupiter (5.5 AU, −140 °C from Table 1).…”

“…Sun et al performed a LILT study on a triple-cation PSC device fabricated using a p-i-n architecture, which looked at simulated Martian surface conditions. 2 Their work showed long-term stability of PSCs operating in Martian surface conditions and noted that device performance was actually improved slightly after a simulated Martian day. 2 Sun et al also confirmed that low-temperature induced phase transitions could contribute to the self-elimination of intrinsic defect states, improving the device efficiency.…”

“…Previous LILT studies 1,2 looking at different PSC device structures have observed similar performance trends with respect to temperature and light intensity as we report here. Brown et al demonstrated temperature-dependent EQE and LILT J – V measurements in Mars, Jupiter, and Saturn environments for a triple-cation PSC device fabricated using an n–i–p architecture, meaning that the cell is illuminated from the electron transport layer (ETL) side.…”
