a Schematic illustrations of the device structure (middle), as-cast (top) and annealed (bottom) ZnO/BHJ/MoO3 interfaces under forward bias in dark. b Schematic diagrams illustrating the working mechanism of the dual-mode OPD operated in PV (reverse bias) and PM (forward bias) modes. c J–V curves of as-cast and dual-mode devices in dark and under illumination (850 nm, 0.737 mW cm−2). d EQE spectra and e D* spectra of as-cast and dual-mode devices operated in PV (−2 V) and PM (+2 V) modes.
