  • Intensity measurement and temperature measurement with the ability to normalize the data points to Standard Test Conditions (STC) or other user specified conditions.
  • Most powerful and advanced I-V curve software, including powerful curve fitting algorithms, with three (3) different curve fitting models and seventeen (17) different weight function models.
  • Ability to determine Thermal Coefficients of various cell parameters.
  • Virtual cell sorting according to user defined classifications.

Various models of the available Cell Testers are listed here. Customer needs to specify the solar cell size (area of illumination) and the maximum short circuit current (I_sc) capability of the solar cell. Any of the Solar Simulator models listed herein can be integrated with any of the listed I-V Measurement systems with Standard IV Measurement software or Advance IV Measurement software. We can also provide custom chucks, usually at no extra charge.
