Quantum Efficiency

The PVE300 is an essential tool in the photovoltaic research and production line quality processes, employed in the accurate determination of solar cell spectral response and efficiency. The system features full compatibility with all types of photovoltaic devices, materials and architectures, including: Si, CdTe, CIGS, CIS, Ge, dye-sensitised, organic/polymer, tandem, quantum well, quantum dots, chalcogenides and perovskites solar cells. The system works with a tunable light source based on xenon-quartz tungsten halogen dual source/single monochromator over a wide range of operation (300-2500nm) for: • Direct determination of device spectral response. • Direct determination of device external quantum efficiency (EQE/IPCE, %) • Direct determination of total reflectance, R and transmittance, T, to convert EQE to internal quantum efficiency (IQE, %).
