QUANTUM EFFICIENCY SYSTEMSOFTWAREs
QE characterization Software
FYTRONIX IPCE CHARACTERIZATION SYSTEM includes
This system analyze quantum efficiency (EQE) characteristics of solar cells,
Quantum efficiency (QE) – also referred to as Incident Photon to Charge Carrier Efficiency (IPCE) - indicates the ratio of the number of photons incident on a solar cell to the number of generated charge carriers.
