Description:

Colloidal quantum dots are increasingly employed in display systems for their unbeatable light output quality. At the same time, their light absorbing qualities are highly appreciated in photodetector and sensor systems, especially in the infrared wavelength spectrum beyond the silicon cut-off at 1100 nm. In this paper, we introduce Pb-free absorbers in thin-film photodetector stacks with external quantum efficiencies above 30% in the short-wave infrared (SWIR) range. These devices are integrated in high-resolution and high pixel density image sensors enabling augmented vision.
