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.

■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
