Reliable and accurate characterization of photovoltaic devices

Take control of your solar cell measurements — no programming knowledge necessary

Overview | Specifications | Gallery | Software | Accessories | Resources and Support

The Ossila Solar Cell I-V Test System is now available as complete kit with the new Ossila Solar Simulator. Order yours today and start characterizing solar cells with ease!

The Ossila Solar Cell I-V System is a low-cost solution for reliable characterization of photovoltaic devices. The PC software (included with all variants of the system) measures the current-voltage curve of a solar cell and then automatically calculates key device properties. In addition, I-V measurements can be performed periodically over time to track the stability of these properties.

The system is available with either manual or automatic pixel switching (if you are using one of Ossila's substrate systems), or without a test board for use with your own substrate and testing system or if you already own one of our test boards. Please refer to the table under the specifications tab if you are not sure which model you should choose.

Solar Cell I-V Test System Features

Calculates Device Properties

Calculates Device Properties

The included PC software automatically calculates key properties of solar cells from the measured I-V curves. These properties include: the power conversion efficiency (PCE), fill factor (FF), short-circuit current density (Jsc), open-circuit voltage (Voc), maximum power (Pmax), shunt resistance (Rsh), and series resistance (Rs).

Rapid Characterization

Rapid Characterization

If you are using one of our substrate systems, the Solar Cell I-V System can be purchased with a multiplexing test board (just select the 'automated' variant of your choice in the drop-down list), which enables automatic pixel switching. As an added bonus, the temperature and light will also be recorded during the measurement!


Easy to Use

Just plug in the system, install the PC software, and you're ready to go! The intuitive interface and clean design makes the Solar Cell I-V System easy-to-use, simplifying the characterization of solar cells.

Wide Measurement Range

Wide Measurement Range

The built-in source measure unit is capable of delivering voltages between -10 V and +10 V, with a maximum resolution of 170 μV, and measuring currents from as low as ±10 nA up to ±200 mA.

Measure Device Stability

Measure Device Stability

By performing repeated current-voltage measurements over an extended period of time, the stability of key device properties can be tracked.

Multiple System Types Available

Multiple System Types Available

Choose from our range of system types (automated or manual) depending on your requirements. If you are unsure which model to select, refer to our comparison table on the specifications tab or contact us for advice.

The current-voltage measurement is controlled using intuitive and user-friendly PC software. All of the measurements can be fully customised, allowing you to tailor the software to your experiment.

With the PC software, you can:

  1. Perform current-voltage measurements anywhere between -10 V and 10 V.
  2. Take high resolution measurements, with voltage increments as low as 170 µV.
  3. Manage the experiment more directly, with custom settle times between applying voltage and measuring current.
  4. Measure device hysteresis by perform consecutive measurements in forwards and backward directions.

The software has 3 measurement tabs: Solar Cell Characterization, Stabilised Current Output, and Solar Lifetime Measurement. 'Characterization' performs I-V measurements and calculates the important device properties, the 'Stabilised Current' tab allows you to determine how the current output of your device evolves over time using, and the 'Lifetime' tab enables you to track key device properties (PCE, FF, Jsc, Voc) over an extended time by performing periodic I-V characterization. Between measurements the solar cell can be held at open-circuit, short-circuit, or maximum power.

FTO Substrates: Adapting Unpatterned Substrates for Photovoltaic Devices

As part of our photovoltaic substrate system, Ossila offers patterned indium tin oxide (ITO) substrates which are designed to work with our evaporation masks to create multi pixel devices. The electrode contacts on the ITO substrate also align with the connection pins in our electronic test boards, which lets us measure devices quickly and easily.
