Create the Future of Solar With Better Photovoltaic Testing

Solar-powered devices are one of the keys to creating a cleaner, more sustainable world. Making these devices effective and scalable means creating realistic and repeatable test conditions. When researching and developing PV devices, your light sources should never be “good enough.”

People depend on your research. You need to depend on your solar simulation.

At G2V, we’ve created large- and small-area solar simulation lights that provide the precision you need to accurately innovate, test, and iterate – easily, efficiently, and repeatedly.

You’re building the future. We’ll provide the light.

How Precision Light Sources Change The Future of Photovoltaic Testing

PV R&D is changing the world, whether it’s mounted on a rooftop or in a field of concentrated photovoltaic (CPV) modules. As we rely more and more on the power of solar, solar relies more heavily on getting it right, from individual cells to the solar back sheets. LED solar simulators are giving researchers the tools they need to create more accurate and scalable devices.

Our comprehensive article can help you go from the theoretical basics up to the most cutting-edge PV research, including:

Customize the intensity and wavelength profiles

We test the performance of our perovskite solar cells in a special chamber that controls variables like humidity and temperature to measure their behavior in real-life conditions. At the heart of our chamber is solar illumination, provided by the G2V Sunbrick simulator. The ability to customize the intensity and wavelength profiles, all while maintaining excellent uniformity and stability has been key in our perovskite manufacturing process. The integration options of the Sunbrick have allowed us to control our solar cell characterization and chamber’s operation in a unified manner

Photovoltaic Testing Frequently Asked Questions (FAQs)

I’m developing a solar cell with a wider bandwidth of spectral responsibility. Can an LED solar simulator produce the light I need further in the infrared region?

Yes. LED technology has come a long way and continues to develop at a rapid pace, which has allowed longer and longer wavelength infrared LEDs to become commercially available.

Aren’t long-wavelength infrared LEDs so expensive that the solar simulator I need will cost too much?

No. Infrared LEDs are somewhat more expensive because they are newer technology, but G2V has worked hard to ensure that the overall solar simulator cost is on par or cheaper than competing technologies.

I’m moving from small device testing to large solar panels. Do you have a solution for that?

Yes! For large-area solar simulation, see the G2V Sunbrick, which can be tiled into arrays as large as you need.

I’m testing devices with specific current and voltage ranges, and am unsure if the Pico’s IV module will meet my needs.

If you haven’t gotten the answers you need from the Pico spec sheet, please get in touch and we’ll be happy to discuss your particular application.
