USB-Powered PV Reference Cell with Calibrated Irradiance Display
Irradiance-calibrated reference photodiode for solar cell testing
Overview | Specifications | Features | Gallery | Software | In the Box | Accessories | Resources and Support
The Ossila Reference Solar Cell contains an irradiance-calibrated photodiode for trustworthy calibration of your solar simulator. The integrated display provides a convenient way to monitor your solar simulator, showing real-time irradiance measurements up to 137 mW/cm2. This compact device is ideal for verifying 1 Sun illumination across different photovoltaic testing setups and different light sources.
The spectral flattening filter ensures that the reference cell consistently reads 100 mW/cm2 under 1 Sun illumination from different light sources (between 400 - 1100 nm). The reference solar cell offers reliable readouts in varying lab conditions, ensuring the accuracy of your testing set up.

Reference Solar Cell Features
Quick and Easy Verification
The silicon photodiode calibration outputs 100 mW/cm2 under 1 Sun illumination. It is accurate to ± 0.01 + 0.15% mW/cm2 between 0-137 mW/cm2.
This allows the Ossila Reference Solar Cell to verify solar simulator performance in seconds.
Compact and USB Powered
The intuitive design combines a calibrated silicon photodiode and an integrated irradiance display in one compact unit. It can be powered via the USB port, with no need for an additional power supply. To get up and running immediately, simply plug it in and start measuring.
Compatible with Different Solar Simulators
The integrated optical filter ensures a flat spectral response over 400–1100 nm, providing reliable irradiance measurements under different light sources. The reference solar cell can therefore be used to confirm 100 mW/cm2 under various arc lamps or LED light sources.
Easily Collect and Record Data
Read the irradiance and temperature measurements directly over USB for more automated data logging and control.

How to Check Solar Simulator Calibration
It is important to ensure that your solar simulator is outputting a consistent spectral output. Different solar simulators will have different bulb lifetimes, and the spectrum delivered by a solar simulator may change over time - both in the short and long term. Therefore, you should check the calibration of your solar simulator periodically. This way you will be sure that your solar simulator continues to emit light that accurately replicates the solar spectrum.
