Solar Simulator
The improved solar simulator has slightly increased spectral coverage across the visible spectrum, and reduced spectral deviation compared to previous versions, while still maintaining 1 Sun Irradiance between 380 – 1000 nm.
While both version solar simulators achieve AAA classification over a 15 mm area, the new solar simulator (released January 2026) has a marginally improved spectral match. Previous classification graphs (for Solar Simulators purchased before 2025) can be found on our Classification Data page.

Software
Solar Cell I-V
With the PC software, you can:
- Perform current-voltage measurements anywhere between -10 V and 10 V.
- Take high resolution measurements, with voltage increments as low as 170 µV.
- Manage the experiment more directly, with custom settle times between applying voltage and measuring current.
- Measure device hysteresis by perform consecutive measurements in forwards and backward directions.
The software has 4 measurement tabs: Solar Cell Characterization, Stabilized Current Output, Solar Lifetime Measurement, and Maximum Power Point Tracking. 'Characterization' performs I-V measurements and calculates the important device properties, the 'Stabilized 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 'Maximum Power Point' tab tracks the maximum power point over time, as well as the current density Jmp and operating voltage Vmp.

Complete, Reliable Characterization
Complete Measurement Setup
Everything you need for reliable photovoltaic characterization. Perform I-V sweeps to find key device performance metrics, run lifetime measurements for degradation studies, or use as a soaking system to precondition cells. Fine-tune testing parameters and build bespoke measurement routines that match your exact needs.
Five Independent Channels
Output voltage and simultaneously measure current and/or voltage using the two SMU channels, while two additional voltmeter channels let you monitor voltage from external components. Plus, you can integrate external control or automation into your workflow with the shutter/trigger channel.
Adapt the Spectral Output
Reliably and accurately mimic the solar spectrum in your photovoltaic research with a calibrated array of light emitting diodes. Change the total irradiance output or control the power output of each LED individually. With a tunable spectrum, align your testing with specific lighting spectrum conditions, even to test indoor photovoltaics according to newly defined standards.
