Abstract
A pixel with enhanced quantum efficiency comprises a semiconductor body that has a first surface configured as an entrance surface and a light capturing region configured for capturing light that is incident on the first surface. The pixel further comprises a structured interface, isolation layers on at least two surfaces of the semiconductor body that are perpendicular to the first surface, and a filter element that is arranged at a distance from the first surface such that light that is incident on the first surface at an angle of incidence smaller than a critical angle impinges on the filter element.
