Researchers studying solar cell longevity use mathematical models to predict operational lifespans under normal conditions. The Arrhenius equation provides the standard data on the relatively short lifespans of solar cells at elevated temperatures, the equation extrapolates the lifespan of the same cells if they were to operate in milder conditions, where direct testing would require impractically long observation periods.
