Fig. 4: Stability of the pero-Ph-Se-Cl-based devices.
From: Strain regulation retards natural operation decay of perovskite solar cells
a, Current–voltage curves of the pero-SCs. b, Stability of the pero-SCs based on FAPbI3/PEAI/spiro-OMeTAD in the cycling mode. c, Stability of the pero-SCs based on FAPbI3/BDT-DPA-F in the cycling working. The temperature of the device fluctuated from about 85 °C under illumination to room temperature in the dark. d, Stability statistical graphs of the pero-SCs based on FAPbI3, FA0.92MA0.08PbI3 and Cs0.05FA0.7MA0.25PbI2.6Br0.4 working in the continuous mode (108 h) and the cycling mode (9 day/night cycles, illumination 108 h). Error bars represent the standard deviation of 10 devices for each condition.
