Quantum efficiency measurement system (QEX10)Ampliar
PVMeasurements QEX10 is a turn-key solution for measuring quantum efficiency/incident photon conversion efficiency of photovoltaic cells. It measures spectral response of solar cells in a range of 300-1100 nm, calculating short circuit current using reference spectrum AM1.5. Aside from external quantum efficiency (EQE), the tool also allows one to measure internal quantum efficiency (IQE) of non-textured solar cells with the equipped diffusion reflectance meter. In addition, the system offers a DC mode measurement capability and a voltage bias capability of up to ±2.5 V.
