A semiconductor component for detecting electromagnetic radiation includes a contact between a metal and a semiconductor. The semiconductor has at least one metal-chalcogenide compound semiconductor as an optical absorbing material or is configured completely from said semiconductor. This allows a cost-effective component to be produced which reacts to electromagnetic radiation in a specifically defined manner. The semiconductor component can be used in an electronic component and a sensor system. A method is also described for producing a semiconductor component by bringing a substrate into contact with a solution, in which a precursor of metal-chalcogenide compound semiconductor is dissolved and/or suspended.
