Fig. 5

a Energy-level diagram of the IS-OPVs. b J–V curves of the IS-OPVs prior to stretching. c External quantum efficiency (EQE) spectra of the IS-OPVs with Ter-D18:Y6 and PM6:Y6 active layers. d Normalised power conversion efficiencies (PCEs) of the IS-OPVs under tensile strain. e Stretchability of the IS-OPVs compared with that of previously reported systems, expressed as the initial device performance versus the strain at which 80% of the initial PCE (PCE80%) is retained. The PCE80% values for previously reported devices were estimated by interpolation. f Normalised PCE of the IS-OPV with the Ter-D18:Y6 active system under repetitive stretch–release cycles at 10% and 20% tensile strains. The error bars in the plots indicate standard deviations (based on three devices).
