Primary reference solar cell.

Alfred hicks who created the graphics used in this report. The level primary reference is also the highest attainable by any pv device. The solar reference cell unit includes an encapsulated silicon cell mounted in a sealed aluminum housing. 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.

1 power source switch circuit for primary battery and energy harvesting device 2 voltage reference circuit for internal block. Historically reference cells calibrated in sunlight have been called primary cells and cells calibrated in solar simulators are called secondary cells. 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. A primary reference solar cell calibration technique recently established at the korea institute of energy research in korea is introduced.

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. And bill hadley alex wolf and j a. The esti reference cell set constitutes the highest level i e. Once we obtain a reference cell we subject it to carefully devised calibration procedures that minimize errors from the temperature dependent spectral correction.

The world pv scale standard is recognized as an international standard for calibrating reference cells used in the characterization of solar cells and modules. A solar cell or a photovoltaic cell is a device that converts photons from the sun solar light into electricity. The atonometrics pv reference cell provides high accuracy outdoor solar irradiance measurements for long term pv system monitoring. An integrated pt 100 rtd provides cell temperature measurement.

Woodhouse whose prior work on iii v solar cell cost modeling we built upon. The results obtained using this calibration technique are shown with a. In general a solar cell that includes both solar and nonsolar sources of. Primary reference of pv reference cells for measurement of solar irradiance at the esti laboratory.
