Frontiers in Photosensor Materials and Designs for New Image Sensor Applications

Certain applications of image sensors require capabilities that are beyond the technology of current image sensors, such as automated color-based quality inspection systems operating under varying levels of illumination. This paper serves to provide a brief overview of image sensor technologies involving the use of alternative photosensor materials (organic semiconductors and perovskites) being developed to meet these needs. The discussion around such developments is typically confined to chemistry and physics “silos”; by publishing in this special edition, the authors hope to bridge the knowledge gap between scientists developing new photosensor materials and engineers developing image sensors for new machine vision systems.
