Primary Reference Solar Cell

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.

Primary reference solar cell.

The solar reference cell unit includes an encapsulated silicon cell mounted in a sealed aluminum housing. In general a solar cell that includes both solar and nonsolar sources of. An integrated pt 100 rtd provides cell temperature measurement. A solar cell or a photovoltaic cell is a device that converts photons from the sun solar light into electricity.

Primary reference of pv reference cells for measurement of solar irradiance at the esti laboratory. Colantonio for informative discussions on these topics. The results obtained using this calibration technique are shown with a. And bill hadley alex wolf and j a.

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 level primary reference is also the highest attainable by any pv device. Woodhouse whose prior work on iii v solar cell cost modeling we built upon. 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.

The atonometrics pv reference cell provides high accuracy outdoor solar irradiance measurements for long term pv system monitoring. Alfred hicks who created the graphics used in this report. 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.

Once we obtain a reference cell we subject it to carefully devised calibration procedures that minimize errors from the temperature dependent spectral correction. Historically reference cells calibrated in sunlight have been called primary cells and cells calibrated in solar simulators are called secondary cells. The esti reference cell set constitutes the highest level i e. We are the only laboratory certified to calibrate primary reference cells secondary reference cells secondary reference modules cells and modules.
