Primary reference solar cell.

In general a solar cell that includes both solar and nonsolar sources of. The level primary reference is also the highest attainable by any pv device. Once we obtain a reference cell we subject it to carefully devised calibration procedures that minimize errors from the temperature dependent spectral correction. A solar cell or a photovoltaic cell is a device that converts photons from the sun solar light into electricity.

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. The esti reference cell set constitutes the highest level i e. The results obtained using this calibration technique are shown with a.

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. 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. Alfred hicks who created the graphics used in this report.

The solar reference cell unit includes an encapsulated silicon cell mounted in a sealed aluminum housing. A primary reference solar cell calibration technique recently established at the korea institute of energy research in korea is introduced. We are the only laboratory certified to calibrate primary reference cells secondary reference cells secondary reference modules cells and modules. 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.
