a IPCE spectra, b J–V curves, and c transmittance spectra of STC and FP-STC devices. d Photograph of corresponding devices. The thickness of each layer was re-adjusted to maximize visible light transmission. The top MAM layer consists of 30 nm outer MoO3, 8 nm Ag interlayer, and 10 nm inner MoO3. The PbS thickness is 120 nm. DBR-C, which mainly reflects NIR, consists of 5 pairs of 160 nm SiO2 and 96 nm TiO2
