Spectral selective photodetectors over different wavelength ranges are critical for applications in imaging, environmental monitoring, optical communications, and the Internet-of-things (IoT). The present available commercial photodetectors have a broadband photoresponse and require different external optical filters to block the undesired light. However, the use of the external optical filters has technical limitations for use in curved or flexible large area photodetectors, as the function of the optical filters depends critically on the difference in the interference of the optical path in optical filters. The understanding of the dynamics of the charge carriers is critical for the development of the high-performance filter-free spectral selective organic photodetectors (OPDs). This chapter presents the generation, transport, and collection of charge carriers in OPDs and strategies for achieving spectral selective photodetection using broadband light-absorbing photoactive materials.
