摘要

Perovskite solar cells (PSCs), have exhibited potential value for revolutionizingphotovoltaic technology for space applications, and they have passed a seriesof tests in a simulated space environment. Nevertheless, the simulated spaceenvironment on land is definitely distinguished from the real-space conditions,and the results cannot completely represent the real operating state ofPSCs in space. Herein, PSCs mounted on a high-altitude balloon are launchedinto near-space and the current–voltage characteristics are measured in situthroughout the 19-h flight, during which the PSCs are exposed directly tonear-space and experience wide temperature variation, vacuum, and strongirradiation. Thus, the diurnal performance evolution of PSCs is obtained forthe first time and a possible variation mechanism is identified. The PSCspresent expected stability and a champion power density of ≈12 mW cm~(?2)at noon, which is demonstrated as the highest result achieved in near-spacefor PSCs. Additionally, despite a complex degradation process, the PSCs stilldeliver a high energy density comparable to that of silicon solar cells. Finally,the challenges facing the space application of PSCs are discussed. This workhighlights the feasibility of PSCs in near space and provides direction forfurther exploration.
