Radiation sensitive detector

A method, comprising:

• receiving light in a volume of a back side of a photo-converter;
• producing a photo-current signal indicative of the light using a photodiode of the photo-converter;
• and
• outputting a signal indicative of the photo-current with read-out electronics located on a front side of the photo-converter;
• wherein the front side is located opposite the back side, and wherein a charge barrier resides between the volume and the read-out electronics and closer to the read-out electronics.

A radiation sensitive detector element, comprising:

• a light receiving region, located on a back side of the detector element, that receives light;
• a photodiode, disposed within the detector element, that produces a photo-current indicative of the light;
• and
• read-out electronics, located on a front side of the detector element so that the photodiode is between the light receiving region and the read-out electronics, that process the photo-current and generate a signal indicative thereof;
• wherein the photodiode and the read-out electronics are formed in a common substrate.
