    Spectrum A+

    The computer, the solar simulator, the electronic load and the I-V Measurement software are configured in our factory to ensure easy and fast installation on site.

    Electronic Load

    Coupling our solar simulator to a performant electronic load results in high quality measurements which most demanding users require nowadays.

    Measurement device are available in two types, Basic or Professional

    Basic measurement system

    Our IV-System Basic is built around the well-known Keithley 2401 Source meter. This proven instrument has all it takes to measure IV-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 source meters that interface by USB, this instrument can only be controlled by a GPIB interface. In our basic IV-System we include a GPIB/USB interface to make sure there are no issues in getting the source meter connected to a computer.

    When measuring solar cells it is very important to use a thermostated sample holder. Sample holders prevents heating up of the solar cell material.

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

    Note that the Tracer IV-Curve Software is required to operate the IV-System Basic.

    Key features

    • Tool for measuring IV-curves (both dark and illuminated)
    • Current range min. 10pA and max. of 1A
    • Voltage range 1µV to 20V
    • Including GPIB interface
    • Including class A Pt100 temperature sensor with computer interface

    I-V Measurement Software

    To ensure a correct powerful control of the equipment, the user-friendly Tracer IV-Curve software is required for each I-V Measurement system. The numerous functions range from doing basic I-V curve measuremens to most advanced analysis.

    Tracer is the all-in-one solution for the measurement and elaboration of IV-curves for solar cells and modules. Tracer is the core application that will help you to characterize your solar cells and modules. Many institutes and laboratories all over the world work hard on the development of new materials and technologies for photovoltaic applications. One of the main techniques to characterize these devices is to measure its IV curve. An IV curve can be taken from a solar cell by changing the voltage while measuring the light generated current.

    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 providing 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 as 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 IV 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

    Naturally Tracer natively supports the control of all Keithley 2400 and 2600 series source meters. 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.

    I-V Software main window

    Preset configurations are available to ensure fast setting-up of the system.

    Tracer Configurator

    Before you start working with Tracer, you will have to configure your system. This is done by the Tracer Configurator. A tool that completely defines the setup you want to use. Tracer intends to support most instruments available on the market to use as an IV-curve measurement system. You can use for example a Kepco Bop bipolar power supply, add 2 Agilent 34410A DMMs to measure voltage and current, use a National Instruments DAQ card to control the Kepco Bob and get that unused Keithley 2000 DMM to measure a pt100 sensor for the solar cell temperature. This can all easily be deined in the configurator.
