Technique: Quantum Efficiency/ IPCE Measurement System
Acquisition year: 2017
Responsible: Konstantinos Rogdakis /     

Description: QE-R quantum efficiency system is a PV cell tester which can provide cell’s QE (quantum efficiency), PV-EQE (external quantum efficiency), IPCE (incident photon-to-electron conversion efficiency), SR (spectral response), IQE (internal quantum efficiency), Reflectance. Two independent lock-in amplifiers, which monitor the optical power and measure the device signal simultaneously.
