A detector device for detection of electromagnetic radiation impinging on a substrate and generating pairs of majority and minority charge carriers in the substrate, comprises at least one minority charge detection structure for, in a first mode, injecting a majority current so as to create an electric field for directing minority charge carriers towards the at least one minority charge detection structure for detecting minority charge carriers generated in the substrate; two or more minority charge removal structures per minority charge detection structure for, in a second mode, injecting a majority current so as to create an electric field, for draining minority charge carriers towards the two or more minority charge removal structures, away from the associated charge detection structure; and at least one substrate majority charge current sink for extracting the injected majority current.
