a, PV parameters of devices with different passivating agents (15 devices for each type). b, c, Representative J–V (b) and EQE (c) curves of CF3-PA devices with absorber layer thicknesses of 750, 900 and 1,200 nm. d, e, J–V (d) and EQE (e) curves of the best CF3-PA device (with 1.2-μm-thick absorber). The inset in d shows the PCE distribution of 237 CF3-PA devices, showing an average PCE of 20.8 ± 0.5%.
