The loss of spatial resolution in conventional RGB-IR sensors causes aliasing, because IR pixels are segmented within the provided effective pixel area [1,2]. 3-D stacking of photodiode arrays has been reported as another strategy for RGB-IR capture [3]; however, the need for bonding accuracy limits pixel size. Silicon’s weak IR light absorptivity also results in relatively lower IR sensitivity on the part of these image sensors. In contrast, organic photoconductive films (OPFs) have the advantage of allowing
