Overview
Photon Detection Efficiency (PDE) is a measure of how effectively a Silicon Photomultiplier (SiPM) detects incident photons. It is the product of three separate factors.

Pro Tips
Quantum Efficiency (QE) represents the probability that a photon generates an electron-hole pair.
Fill Factor (FF) is the ratio of active area to the total device area.
Collection (or Avalanche) Efficiency (CE) is the probability that a carrier triggers a breakdown.

Fun Facts
"SiPMs are widely used in medical imaging (PET scans) and LiDAR systems."
"PDE is wavelength-dependent, typically peaking in the blue or near-UV range for modern devices."
"Wait, modern SiPMs can achieve PDE values over 50%."
