Reliable and accurate characterization of photovoltaic devices

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


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!

Part of the Institute of Physics award-winning Ossila Solar Cell Prototyping platform, 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. This system is covered by our FREE 2-year warranty.

Key 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

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.

System Selection Guide

The table below will help you determine which system is right for you. The manual version of the system has switches on the test board itself, which the user operates to measure the different pixels on a solar cell device. The automated version of the system uses a multiplexing test board, which switches between these pixels automatically. Test boards for the manual system can be purchased separately here, and user-swappable riser boards for the automated system can be purchased here.

Software

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.

Data is saved to .csv (comma-separated values) files, which are formatted to be easy to read and analyse. Settings are saved along with the data, making it easier to keep a record of the parameters used for each experiment. These settings files can be loaded by the program, and settings profiles can be saved for each different measurement type, allowing you to easily perform repeat measurements or use particular configurations.
