Product information:
       The PVE300 system is a monolithic,turnkey solution for photovoltaic material and device characterization;a key component in research, or as part of a production-line quality process.
       Flexible in use, and compatible with all types of photovoltaic devices, from silicon to 3rd generation devices, the PVE300 permits the quick and accurate determination of solar cell spectral response from which EQE (IPCE) can be determined, and, with the addition of determination of cell transmittance and reflectance, IQE, over a range up to 250-2.5μm.
