Diagram

Diagram demonstrating the relationship between the photosensitive area and the electronic component of a detector element (del).

The equation for the fill factor is included, which describes the percentage of the del that is photosensitive 1. This determines the efficiency of light collection of the del 1.

The electronic component of the del is the limiting factor determining how small the del can be, whilst maintaining a sufficient fill factor 1.
