Abstract
This work shows the effect of sequential and combined space-based stressors on the stability of perovskite solar cells (PSCs). Specifically, PSCs were exposed to simulated Low Earth Orbit (LEO) conditions, incorporating proton (p+) irradiation, light soaking, and thermal cycling. Upon observing the changes in power conversion efficiency (PCE), mobile ion behavior, and structural changes of the perovskite layer, PSCs show a tolerance to p+ irradiation, a healing with light soaking, and a slight degradation due to thermal cycling. We observe an anti-correlation between mobile ion concentration (No) and PCE, where a decrease in PCE leads to an increase in No and vice versa. Under simulated LEO conditions with combined space-based stressors of temperature and light cycling of PSCs, we showcase the role of the hole transport layer (HTL) configuration on the power output of PSCs while in simulated orbit. We demonstrate an improvement in the performance of the bilayer HTL PSC up to 5 orbital cycles, along with higher power output and less variation with temperature when compared to SAM-only and NiOX-only PSCs.
