Inside perovskite solar cell durability and performance testing
Accurately measuring the performance of perovskite solar cells and modules requires significant modifications to long-established testing standards used in silicon PV. Researchers are settling on methods that rely on up to several minutes of constant light exposure and other time-consuming procedures. These may be fine for the laboratory setting, but those looking to produce this technology at scale need standardized methods that can characterize cells and modules at a much faster rate.
