Perovskite solar cells should be subjected to a combination of stress tests simultaneously to best predict how they will function outdoors, according to researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL). Solar cells must endure a set of harsh conditions—often with variable combinations of changing stress factors—to judge their stability, but most researchers conduct these tests indoors with a few fixed stressing conditions. While these tests provide some necessary insight, understanding which stressor applied during indoor tests provided predictive correlations with outdoor operation is critical.
