Fig. 1: Diagrams of perovskite solar cell stability tests.
From: Big data driven perovskite solar cell stability analysis
a General device architecture of a perovskite solar cell. b The distribution of stability protocols used for stability data in the Perovskite Database. c Two possible efficiency decay curves of perovskite solar cells illustrating different types of burn-in behaviors followed by a slower exponential decay. (PCE stands for photoelectric conversion efficiency. T80 is the time for PCE to decay to 80% of the initial efficiency. TS80 is the time for PCE to decay to 80% of the stabilized efficiency (marked as 100%(s)).
