Abstract

The invention relates to an opto-electronic sensor component comprising the following: a first semiconducting layer of predetermined conductivity type and a second layer of different semiconductor or metal conductivity type; a transition region between the two layers; at least one surface region through which the electromagnetic radiation to be detected can pass into the transition region (radiation-side surface region); and an electrode for each layer to connect both layers to an electrical circuit. The electrodes of the two layers are mounted on a surface of the component opposite a radiation-side surface region. This simplifies connection of the sensor component to an electrical circuit mounted on a circuit board or the like.
