EQE spectra of 1.73 eV wide bandgap and 1.23 eV narrow bandgap sub-cells in a tandem device. a For a PCBM/SALD-SnO2/PEDOT:PSS, ICL. c For a C60/SALD-SnO2/PEDOT:PSS ICL. d For a C60/SALD-SnO2/Au/PEDOT:PSS ICL. The Jsc was obtained by integrating with the AM1.5G spectrum. b Fast dark and light J–V scans of tandem cells with different ICLs (measured with 6.76 mm2 aperture area). Source data are provided as a Source Data file.
