Primary Reference Solar Cell

The world pv scale standard is recognized as an international standard for calibrating reference cells used in the characterization of solar cells and modules.

Primary reference solar cell.

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. The results obtained using this calibration technique are shown with a.

The atonometrics pv reference cell provides high accuracy outdoor solar irradiance measurements for long term pv system monitoring. Woodhouse whose prior work on iii v solar cell cost modeling we built upon. 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.

We are the only laboratory certified to calibrate primary reference cells secondary reference cells secondary reference modules cells and modules. Alfred hicks who created the graphics used in this report. Once we obtain a reference cell we subject it to carefully devised calibration procedures that minimize errors from the temperature dependent spectral correction. In general a solar cell that includes both solar and nonsolar sources of.

1 power source switch circuit for primary battery or series solar cell 2 voltage reference circuit for internal block 3 interrupt request control function for power gating switch control. Primary reference of pv reference cells for measurement of solar irradiance at the esti laboratory. Colantonio for informative discussions on these topics. A primary reference solar cell calibration technique recently established at the korea institute of energy research in korea is introduced.

The esti reference cell set constitutes the highest level i e. 1 power source switch circuit for primary battery and energy harvesting device 2 voltage reference circuit for internal block. Historically for space applications primary reference cell calibrations have relied on measurements under spectral conditions as close to air mass 0 as possible with locations such as high. 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.
