Cells Tester A-1417 - Class AAA (Lumartix SA)

Description

Cell Tester A-1417, class AAA 1'400 x 1'700 mm

Numerous of our realizations were built upon customers' requirements.

To save time, we recommend to directly request the quotation from the manufacturer website.

Our Cells Tester equipment consist in arrays of Lumixo light engines. The complete machine is then built for the targeted illuminated area specified by the customer.

This model accepts up to 80 silicon wafer cells 6'' (array of 8 x 10 positions)

Thanks to our Lumixo light engines, the illuminated area of these machines benefits from a continuous and stable irradiation. Our standard systems typically meet the Class AAA required for most of the testing standards specifications.

All our machines are constructed to give an easy access to the illuminating chamber. Furthermore, they come with a network interface to allow remote control of the installation.

I-V System Basic

Our I-V System Basic is built around the well-known Keithley 2401 Source meter. This proven instrument has all it takes to measure I-V curves (both dark and illuminated) on solar cells. The available current range has a minimum of 10 pA and a maximum of 1A, where the voltage ranges from 1μV to 20V. Unlike the more expensive Keithley sourcemeters that interface by USB, this instrument can only be controlled by a GPIB interface. In our basic I-V System we include a GPIB/USB interface for computer connection of the sourcemeter.

When measuring solar cells, it is very important to use a thermostated sample holder, to avoid measurement due to thermal drift of the sample.

Another important parameter for solar cell metrology is the temperature. A high precision, class A Pt100 temperature sensor including computer interface (USB) is provided with this basic IV-System.

Please note that the Tracer I-V Curve Software is required to operate the I-V System Basic.

Key features

I-V System professional

Our I-V System Pro is built around the well-known Kepco Bop bi-polar power supply and 3 Agilent DMMs to realize high quality data acquisition on current, voltage and reference cell. These proven instruments have all it takes to measure IV-curves (both dark and illuminated) on solar cells and modules.

The current range is ±4A, where the voltage range is ±100V. Other ranges are available on request. When measuring solar cells, it is very important to use a thermostated sample holder, to avoid measurement due to thermal drift of the sample.

I-V Measurement Software

A powerful software named Tracer, controlling the electronic load, allows a user-friendly operation, going from simple current-voltage (I-V) plot tracing to more advanced device characterization. It seems logical for this measurement to use a standard power supply, because a power supply is normally used to provide a variable voltage and current. Unfortunately, this would not work for solar cells.

A solar cell generates current, so you will need to have a power supply that sinks this generated current instead of provide it. This can be done with a so called bi-polar power supply (or electronic load). This is a power supply that can sink and source current at both positive and negative voltages. There are many instruments on the market that can be used a such a bi-polar power supply. Some of them are just bi-polar power supplies while others integrate measurement and control capabilities as well.

Tracer will let you define and setup a system based on different instruments to measure your I-V curves. You can add multiplexers to automatically measure multiple cells by using one single measurement system, implement contact checking and measure monitoring solar cells.

Some examples of the supported hardware:

- Keithley 2400 series

- Keithley 2600 series

- HACKL Electronic Loads

- Kepco BOB

- B&K Electronic Loads

- Toellner loads info

- EKO MP-180 Curve Tracer

- National Instruments Data Acquisition

- MODBUS / Ethernet controlled instruments

Of course Tracer natively supports the control of all Keithley 2400 and 2600 series SourceMeters. These instruments have proven their strength over time for the measurement of solar cells. They range from 0.1fA – 20 Amperes.

Tracer is developed with the latest Microsoft.NET Technology, which resulted in a modern ‘Microsoft Office' look and feel. A stable operation on the Microsoft Windows platform is guaranteed (Vista or higher).

Other popular platforms like Linux and MacOS will be supported in the future.

Solar cell probes

The High Resolution Solar Cell Probe is a precise probing unit enabling accurate current/voltage measurements on solar cells.

The High Resolution Probe is designed primarily for probing targets of approximately at least 13 microns in size at a 80 TPI resolution (320 μm per 360° turn). It is available with a magnetic base in either left or right hand models.

The 125 mm x 125 mm scanning area allows positioning on a broad range of solar cell materials. Each axis is spring loaded to prevent backlash, and the control knobs are conveniently placed at the rear of the micropositioner to allow one hand control over three axes at the same time. The probe mount is electrically isolated from positioner body.

Optional: 4-wires Kelvin Configuration

The High resolution Solar Probe can be used in a true 4-wire Kelvin configuration. This means that the possible voltage drop over the current wire is eliminated by measuring the voltage at the sample directly. The wires are electrically isolated from the body. To measure a solar cell in 4-wire Kelvin configuration a second Solar Cell Probe or a base plate with voltage sense is required.

Key Features

- Dedicated probing unit to enable high quality current/voltage measurements on solar cells

- High precision positioning

- 45° angle

- Including solid case

Reference Si solar cell

The standard crystalline silicon reference cell manufactured by ReRa is a high-quality precision sensor for the determination of solar simulator irradiance levels. ReRa uses the Radboud University Nijmegen PV Measurement Facility to calibrate the cells indoor. The calibration is done against an established set of reference cells calibrated at NREL and Fraunhofer ISE. These references are measured each year at the spectroradiometer and broadband intercomparison to ensure traceability.
