a Time variation of ESR spectra of ZnO/PC61BM layered film. b Fitting analysis for the ZnO/PC61BM signal in low magnetic fields at around 321.5 mT (Signal 2 and Signal 3). c Time variation of ESR spectra of ZnO thin film in high magnetic fields at around 327.5 mT (Signal 4). These samples were measured with the same conditions used for the cells.
