A complete system to perform solar cell characterisation

Solar cell I-V test system and solar simulator, available at a discounted price

Overview | Specifications | Gallery | Software | In the Box | Accessories | Resources and Support

The Ossila Solar Cell Testing Kit includes both a source measure unit and an LED-based solar simulator. It is an all-in-one solution for the rapid characterisation of solar cells fabricated with our popular fabrication platform. Using the included Solar Cell I-V measurement software, you can obtain device performance metrics in just a few clicks.

The kit comes with either the manual I-V test system or automated I-V test system and is compatible with our 20 mm x 15 mm and 25 mm x 25 mm substrate designs.

The manual system comes with the solar simulator head, adjustable z-stage and optical breadboard, our dual-output source measure unit (Solar Cell I-V software included) and electrical test board, and all the required connection and power cables. This system offers maximum flexibility as it allows you to use the source measure unit and solar simulator independently as well as together.

The automated system is assembled with the solar simulator head mounted directly to our automated solar cell I-V test system. This system provides the quickest and easiest way to characterise your devices thanks to the software-controlled automatic switching of pixels under test in each device.

Why use an integrated I-V test system and solar simulator

Solar cell characterisation involves performing electrical measurements on an illuminated device. To make measurements comparable, the illumination should be standardised. This requires the use of a solar simulator. We have designed the I-V test system and solar simulator to work seamlessly together and tested their performance against other solutions. With our solar cell testing kit, you can be confident that reliable device metrics are only a few clicks away.

Rapid device characterisation with the Ossila Solar Cell I-V software

Solar Cell I-V Test System 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.

The Solar Spectrum The Solar Spectrum

The purpose of a solar simulator is to recreate the sunlight received on Earth. This is easier said than done as sunlight starts its journey in complex nuclear reactions in the sun's core, and is modified on it's journey to us through interactions with the Earth's atmosphere.
