AK-300 Dye-Sensitized Reference Cell

Solar simulator intensity is accurately calibrated for dye-sensitized (DSC) category cells using the AK-300 Dye-Sensitized Reference Cell.

Companies that fulfill a goal to improve solar cell performance and characteristics, can find themselves well positioned as the focus on renewable energy and photovoltaic cells increases. To improve the performance of solar cells, companies test the products during evaluations conducted under standing testing conditions. To ensure accurate measurements are realized, it is important to use reference photovoltaic cells that are accompanied by a calibrated short circuit current as this is adjust the solar simulator intensity for measurement usage.

Konica Minolta Sensing designs Filtered PV Reference Cells have best constancy and accuracy as in accordance with JIS C8904. Used for DCS/DSSC type cells, the AK-300 has the option of being used as a standalone reference. As with all AK series PV reference cells, theAK-300 can be used out of its box along with a temperature sensor (PT-100) and a test report of a short circuit current (lsc). Delivery choices include calibration traceable to AIST.

Spectral mismatch error of less than 1%

By employing the high-accuracy optical filter technology cultivated for our color-measuring instruments, we have succeeded in greatly reducing spectral mismatch, which had been a major problem with conventional cells. Spectral mismatch can be suppressed to 1% or less, even when evaluating solar cell performance using JIS C-8942 Class C solar simulators.

Improved durability against solar simulator light

Standard reference cells using optical filters typically have low durability against exposure to solar simulator light.  This causes changes in characteristics due to the effects of light exposure (solarization) making accurate measurements difficult. AK series Reference PV Cells have a high durability against exposure to light, greatly reducing solarization and ensuring stability.

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.
