PV Measurements System


PV Measurements offers to combine a Spectral Response/QE/IPCE system with an I-V system into one compact measurement system. Depending upon the configuration required for your devices,it may share a test fixture.This reduces overall system cost.



Product's Feature

Short-circuit current density uniformity
Optional:
Automatic mapping feature
Dual optical light control
Variety of sample states
Full solar spectrum coverage from 300nm-2000nm
Suitable for all kinds of solar cell QE measurement
AC/DC Pre-Amp Dual Measurement Modes
  AC mode QE/IPCE measurement is useful for measuring fast response solar cells for example:  amorphous silicon,   monocrystalline silicon, microcrystalline silicon, polycrystalline silicon, CdTe, CIGS, GaAs.
  DC mode with dark sample chamber is used for slow response solar cells such as DSSC, organics solar cell.
  Both modes of measurement in the one instrument provide a versatile solar cell analysis tool for a wide range of applications.
Automatic operation, calibration and test report generation
