Classification: CPC H | IPC H

Claim 0:
1. An optical sensor (110), comprising
a substrate (120);
a photoconductive layer (112) applied to a first portion (116) of a surface (118) of the substrate (120), the photoconductive layer (112) having at least one photoconductive material (124); and
at least one electrode layer (124) applied to a second portion (126) of the surface (118) of the substrate (120), wherein the electrode layer (124), apart from a first edge portion (128) of the electrode layer (124), exhibits a thickness d0, wherein the first edge portion (128) of the electrode layer (124) is covered by an edge portion (130) of the photoconductive layer (112) in a manner that an electrode-photoconductor interface (132) is formed at a surface (134) of the electrode layer (124),
wherein the electrode-photoconductor interface (132) comprises a first segment (138), a second segment (140), and a third segment (142);
wherein a thickness d1 of the electrode layer (124) along the electrode-photoconductor interface (132) within the first segment (138) equals the thickness d0 of the electrode layer (124);
wherein a thickness d2 of the electrode layer (124) along the electrode-photoconductor interface (132) within the second segment (140) is equal to or exceeds the thickness d0 of the electrode layer (124); and
wherein a thickness d3 of the electrode layer (124) along the electrode-photoconductor interface (132) within the third segment (142) decreases continuously and monotonically along the electrode-photoconductor interface (132) within the third segment (142) towards an edge of the electrode layer (146).
