Extended Data Fig. 7: Thermal stability of the pero-Ph-Se-Cl-based devices.
From: Strain regulation retards natural operation decay of perovskite solar cells
(Device structure: FTO/SnO2/FAPbI3/BDT-DPA-F/Au). a, PCE tracking of the pero-SCs without and with Ph-Se-Cl modification under 85 °C in a N2-filled glovebox. Data from six cells are collected and presented as mean values ± standard error of the mean. b, PCE tracking of the pero-SCs without and with Ph-Se-Cl modification under the cycled thermal (12 h RT and 12 h 85 °C) working modes according to the ISOS-T-1 suggested protocol.
