With the current increasing focus on renewable energy, solar cells (photovoltaic cells) are in the spotlight. As companies strive to improve the performance and characteristics of solar cells, it is necessary to perform evaluation of each product under standard test conditions. For accurate measurements, it is necessary to utilize a reference photovoltaic cell with a calibrated short-circuit current to adjust the intensity of the solar simulator to be used for measurements. The AK-200 can be used as a standalone reference for c-si cells. All AK series Reference PV Cells come ready to use right out of the box with a PT-100 temperature sensor and a test report of short circuit current (Isc). They can also be delivered with calibration traceable to NREL or AIST.

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.
