AK-110 Micro Silicon Reference Cell

To calibrate solar simulator strength for u-si cells accurately use the AK-110 Micro Silicon Reference Cell. Additionally, the AK-110 Micro Silicon Reference Cell is designed for use with the AK-100 a-si reference cell. For tandem type cells, the AK-110 can also be used as a standalone.

Ongoing interest in renewable energy is keeping solar cells, otherwise known as photovoltaic cells, in the spotlight. To exceed expectations and continuously improve solar cells, including the cells characteristics and performance, companies are required to evaluate their solar products in environments that allow for standardized testing. Reference photovoltaic cells that have a calibrated short circuit current are used to change the strength of specific solar simulators that are used to conduct and record measurements.

Amongst available Filtered PV Reference Cells, Konica Minolta Sensing has the most concise and dependable industry instruments (according to JIS C8904). Although it can be used as a standalone reference, the AK-110 Micro Silicon Reference Cell can also be used with an AK-100. Individually or in conjunction with another AK series instrument, the AK-110 is for tandem type (a-si/u-si) cells. These reference cells are delivered with calibration that is traceable to AIST or NREL upon request. Additionally, all Reference PV Cells in the AK series are ready to be used as soon as they are removed from the box. Use with a test recording of short circuit current (lsc) and a PT-100 temperature sensor.

Crystalline SI Solar Cell Product Description

AK-110 Micro Silicon Reference Cell

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.
