Patent ID: 7053457

Claim:
An optoelectronic component for conversion of electromagnetic radiation to an intensity-dependent photocurrent comprising a substrate with a microelectronic circuit, on whose surface a first layer which makes electrical contact with this and is composed of intrinsically conductive amorphous silicon or of its alloys is arranged, with at least one further optically active layer being arranged upstream in the light incidence direction of the first layer wherein the first layer is produced from intrinsically conductive amorphous silicon by alloying it with carbon in a concentration of 2 to 15% by atomic weight, such that the band gap of the semiconductor material in the first layer is at least 1.8 eV, wherein the optoelectronic component converts electromagnetic radiation into the photocurrent in response to receiving the electromagnetic radiation by the first layer, and converts a greater proportion of electromagnetic radiation having wavelengths less than about 680 nm when received by the first layer than electromagnetic radiation having wavelengths greater than about 680 nm when received by the first layer.
