a Schematic cross-sectional view and b absorption profile of the dual-mode narrowband OPD, comprising a layer configuration of glass/ITO/ZnO (10 nm)/PM6:IT-4F (1:1) (3.5 µm)/MoO3 (5 nm)/PTB7-Th:COTIC-4Cl:Y6 (1:1.05:0.45) (670 nm)/ZnO (10 nm)/Ag. c EQE spectra measured for the OPD operated under forward biases of 1.0 and 2.0 V, showing a narrowband spectral response in the NIR-I range, with a peak wavelength of 814 nm, and the ones measured for the OPD operated under reverse biases of −1.0 and −2.0 V, showing a narrowband spectral response in the NIR-II range, with a peak wavelength of 1108 nm.
