Abstract
The disclosure refers to a photosensitive pixel structure that includes a substrate layer and an interface layer. The interface layer is provided at least partially on a first surface of the substrate layer and the interface layer at least partially includes a first material layer and the interface layer at least partially includes a second material layer covering the first material layer such that the first material layer is at least partially sandwiched between the second material layer and the substrate. The second material layer has a thickness chosen from a range of 200 nm-600 nm, 300 nm-500 nm, or 320 nm-450 nm. The disclosure further refers to an array and an implant that includes a pixel structure and a method for providing a pixel structure.
