a J–V curves for the DIO processed and TCB processed OSCs based on PM1:BTP-eC9. b J–V curves for the DIO processed and TCB processed OSCs based on PM6:BTP-eC9. c EQEEL of OSCs at various injected current densities. d Detailed energy loss in the DIO-processed and TCB-processed OSCs based on PM1:BTP-eC9. e Detailed VOC loss in the DIO processed and TCB processed OSCs based on PM6:BTP-eC9. f Comparison of PCE versus ∆E3 in reported OSCs with over 18% efficiency. g Light stability tests for PM6:BTP-eC9 based OSCs with different treatments, all OSCs were encapsulated and stored under continuous illumination equivalent to 1 sun in air. Source data are provided as a Source Data file.
