Apparatuses for radiation detection including absorber tiles with a semiconductor material or a perovskite material disposed between the absorber tiles and methods of manufacturing the same

A detector for electromagnetic radiation comprising:

• a first pixelated electrode layer, the first pixelated electrode layer comprising a plurality of electrode pixels;
• a first layer comprising a plurality of tiles, the plurality of tiles comprising a material configured to absorb and convert the electromagnetic radiation, wherein the first layer comprises gaps between the tiles, wherein the gaps are filled with at least one of at least a first semiconductor or at least a first perovskite and the plurality of tiles comprise at least a second perovskite, the second perovskite being the material configured to absorb and convert the electromagnetic radiation;
• a second electrode layer;
• and
• a second layer between the first, pixelated electrode layer and the first layer, wherein the second layer is an adhesion promoting layer, the second layer comprises at least one of a second semiconductor, a conductor or a third perovskite.
