An example includes a method for producing a multipixel detector, the method including: providing a bottom layer including a first and a second bottom electrode, depositing an electrically insulating layer on the bottom layer, forming a first opening through the electrically insulating layer, depositing a first photon absorbing material in the first opening, forming a second opening through the electrically insulating layer, depositing a second photon absorbing material in the second opening, planarizing the deposited electrically insulating layer, the first photon absorbing material, and the second photon absorbing material to form a flat surface, and forming a common top electrode on top of the flat surface.
