Light spectral portion`s light intensity determining device e.g. optical multi-channel analyzer, has structured organic photoactive semiconductor layer arranged between anode and cathode

摘要

The device has a polychromator dispersing light into the spectral portions. A laminar photodetector (21) has a structured-laminar anode (22) that is provided with partial anodes (22a) according to pixeling of the photodetector. A structured or unstructured cathode (23) corresponds to the cathode. A structured organic photoactive semiconductor layer (25) is arranged between the anode and the cathode. A light-sensitive surface of the photodetector is curved such that the spectral portions impinge in a focus on the surface. The anode or the cathode is attached to a flexible substrate (26). An independent claim is also included for a method for determining light intensity of spectral portions of light.
