a, JV curves of PM6:BTP-eC9 large area and modules made up of one to five single cell devices (2.4 cm2) connected in series for a total area of 12 cm2. Inset: photograph of a five-cell large-area module. b, Outdoor stability of PM6:BTP-eC9 large-area device. c, JV curves of OPV devices based on state-of-the-art blends: P3HT:O-IDTBR (inverted), PTB7-Th:IEICO-4F (inverted), PM6:IT-4F (inverted), PM6:PY-IT (normal) and PM6:(PY-IT:BTP-eC9) fabricated through blade coating in ambient conditions from Eu:Tet inks. d, Molecular structures and images of polymer OLEDs fabricated from Eu-based inks. e, JV and luminance curves of Super Yellow devices fabricated from different solvents. f, Current efficiency versus current density of Super Yellow OLED devices. g,h, Output curves (g) and transfer (h) curves of O-IDTBR-based OFET devices from CF and Eu inks. VD–S and ID–S are the drain–source voltage and current, respectively. VG–S is the gate voltage and μ is the charge mobility. Sqrt refers to the square root. CB refers to chlorobenzene. i, Comparison of mobility of devices fabricated from CF and Eu in the linear and saturation regimes represented as box plots (sample minimum, 25th percentile, median, 75th percentile and maximum) for n = 12.
