AK-130 Triple Junction Reference Cell (Middle)

This instrument accurately calibrates the intensity of a solar simulator used for the middle part of triple junction cells. The AK-130 Triple Junction Reference Cell (for middle) is ready for use individually. You also have the option of using the AK-130 for triple junction type cells with the AK-140 (for bottom) and AK-120 (for top).

Renewable energy has increasingly gained importance, placing solar based cells like photovoltaic cells, at the forefront. To continue to offer best solar cell performance and qualities, companies are finding it necessary to perform tests on products. Precise measurements are derived from using photovoltaic reference cells that have currents that are calibrated with a short circuit to adjust a solar simulators intensity for measurement usage.

Regarding accuracy and constancy (in compliance with JIS C8904), the industries best characteristics are found in Konica Minolta Sensing’s Reference Cells (Filtered PV). Deliverable with calibration traceable to AIST, Konica’s AK series PV cells have a PT-100 temperature sensor. They also have a test report of short circuit current (lsc) and are capable of being used as soon as they are taken out of their box. Both the AK-120 and the AK-140 can be used with the AK-130 for triple junction cells; AK-130 also available for use as an individual reference.

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.
