AK-200 Crystalline Silicon Reference Cell

Solar cells, also called photovoltaic cells, are highlighted more as the focus on renewable energy increases. To provide best performing solar cells, companies are evaluating the performance of products under common testing conditions. Users can get accurate measurements from the products if they use AK-200 crystalline silicon reference cells that have a calibrated short circuit current. These reference cells are used to adjust solar simulator intensity when used for measurements. AK-200 Crystalline Silicon reference cells are used as standalones for c-si cells. Any reference PV cell in the AK series is ready to be used with a PT-100 temperature sensor and the short circuit current test report as soon as its removed from the box. Delivery options include calibration that’s traceable to AIST or traceable to NREL.


AK-200 Crystalline Silicon Reference Cell


Improved reflection characteristics

Error in short-circuit current (Isc) due to multiple reflection is greatly reduced. Improvements in the optical structure suppress multiple reflections and reduce the 1.3% error of conventional products to 0.0%.

Maintain standard test condition of 25°C

A PT-100 temperature sensor is integrated into the package of the AK series cells, and can be connected to a temperature-controlled stage for reference PV cells to easily achieve and maintain the standard test condition (STC) of 25°C.

Calibration Certificate

A calibration certificate traceable to the National Renewable Energy Lab in the United States or Japan’s National Institute of Advanced Industrial Science and Technology is available as an optional accessory

Software for calculation of spectral mismatch

Every AK series cell includes our Spectral Mismatch Software.  The software can be used to determine the spectral mismatch between the AK Series PV Cell and any manufactured solar cell.  The software is available for download as a trial from our website.
