An optical sensor, a detector comprising an optical sensor for optically detecting at least one object, and a method for manufacturing the optical sensor. An optical sensor (110) includes a substrate (120), a photoconductive layer (112) having at least one photoconductive material (114), and at least one electrode layer (124). Except for a first edge portion (128) of the electrode layerThe electrode layer exhibits a thickness d 0 . A first edge portion (128) of the electrode layer is covered by an edge portion (130) of the photoconductive layer (112) in such a way that an electrode-photoconductor interface (132) is formed at a surface (134) of the electrode layer. The electrode-photoconductor interface (132) includes first, second, and third segments (138, 140, 142). A thickness d of the electrode layer within the first segment (138) 1 Is equal to the thickness d 0 The thickness d of the electrode layer within the second segment (140) 2 Equal to or exceeding the thickness d 0 And the thickness d of the electrode layer in the third section (142) 3 Continuously and monotonically decreases within the third segment towards an edge (146) of the electrode layer. The optical sensor (110) exhibits a linear current-voltage characteristic according to ohm's law. |
