While the latter is able to provide full i v characteristics of a solar cell it is not considered a primary calibration as its accuracy relies on the reference solar cell used to set the standard irradiance conditions and spectral mismatch correction applied due to the non perfect matching of the solar simulator spectrum to the am1 5 reference.
Historically reference cells calibrated in sunlight have been called primary cells and cells calibrated in solar simulators are called secondary cells.
An integrated pt 100 rtd provides cell temperature measurement.
The level primary reference is also the highest attainable by any pv device.

To comply with the wpvs standard and the requirements of iec 60904 2 reference cells must meet a wide range of optical electrical thermal and mechanical criteria and be calibrated and.
This calibration technique is an indoor method that uses a highly collimated continuous type solar simulator and absolute cavity radiometer traceable to the world radiometric reference.

Primary reference of pv reference cells for measurement of solar irradiance at the esti laboratory.
The world pv scale standard is recognized as an international standard for calibrating reference cells used in the characterization of solar cells and modules.
The atonometrics pv reference cell provides high accuracy outdoor solar irradiance measurements for long term pv system monitoring.
Once we obtain a reference cell we subject it to carefully devised calibration procedures that minimize errors from the temperature dependent spectral correction.
