Fig. 1

The electrostatic surface potential contour of NFA a L8-BO and b T9SBO-F. The scale bar is from −1.28 (red) to 1.28 eV (blue), D means Debye. c Chemical structure of T9SBO-F. d εr of the organic films. e J–V curve and f external quantum efficiency (EQE) spectra of the devices. The ratio shown in the Figures is PM6:L8-BO:T9SBO-F mass ratio. Source data are provided as a Source Data file.
