QE-R: IPCE Measurement

QE–R quantum efficiency system is a PV cell tester that provides cell’s EQE, IPCE, IQE and spectral response data accurately and rapidly. The quantum efficiency spectra provided by QE–R quantum efficiency system is commonly used by PV researchers to illustrate and study the device design, device performance, process improving, material bandgap, impurity, or traps. Due to its high repeatability and accuracy, the QE–R quantum efficiency system is also used by metrology engineers for spectral mismatch calculation and uncertainty evaluation of PV conversion efficiency.
