Impinging electromagnetic radiation generates pairs of majority and minority carriers in a substrate. A spectrometer device for detection of electromagnetic radiation impinging on a substrate comprises means for generating, in the substrate, a majority carrier current; at least one detection region for collecting generated minority carriers, the minority carriers being directed under influence of the majority carrier current; and means for determining spectral information based on minority carriers collected at the at least one detection region.
