Whether you are manufacturing solar modules for homeowners and businesses around the world, engineering grid-connected photovoltaic power plants, or making solar-driven thermochemical fuel, you’re a leader in renewable energy implementation, and people are counting on you to deliver.
Energy capture and production needs to be reliable, and that includes everything from grid integration to solar cell performance. You need to measure cell-to-module (CTM) loss, increase energy yield, and lower the levelized cost of energy (LCOE). Your automated Quality Control (QC) processes need stable, long-term throughput.
G2V’s Class AAA LED solar simulators provide exceptional spectral match and long-term spectral reliability, so you’ll get the most accurate and repeatable test results.
You’re building the future. We’ll provide the light.
You’re bringing the latest research into the commercial world, making them accessible to the broader public. You want to bring the very best, and for that, you have to deeply understand the science and the ongoing progress.

You’re building something great. Our solar replication technologies mean you don’t have to worry about accurate light.
A solar simulator is only one part of your toolset to validate PV devices, and your production space might be limited. With a small footprint suitable for glovebox integration, you can harness the power of the sun in your hand, giving you the direct light you need for small device areas.
Characterize your PV devices with high-quality sunlight.
Your solutions are as big as your ideas, whether they’re in a foldable thin-film for mobile power or a building-integrated photovoltaic (BIPV) module. Our G2V Sunbrick will allow you to illuminate and test all of it, with a tileable design so you can scale a solution to fit your needs.
Problem: Dr. Sam March, co-founder of Rayleigh Solar Tech, had demonstrated his perovskite technology in the lab at a 1” x 1” scale, but he needed a reliable larger-area solution to reach commercialization.
Innovation: G2V’s Sunbrick provided the large area, reliable solar simulation that Dr. March needed.
Outcome: The G2V Sunbrick was integrated into a testing chamber design that has enabled Rayleigh to quickly progress in their perovskite module testing and commercialization for use in electric vehicles.
G2V doesn’t currently provide automated testing solutions out of the box. However, there is a Python API (included with the Sunbrick and the Pico’s Variable Module) and a LabView DLL (Sunbrick only) so customers can implement a scripted automated solution that fits their needs. We’re always happy to work collaboratively to ensure the fit is right. Furthermore, we’re always building out and planning our future product roadmap; any feature suggestions you have are welcome!
All of our solar simulators are currently calibrated using several detectors calibrated by a third-party lab, which qualify as “gold” cells, all of which are metrologically traceable to NIST. This is done to reduce the reliance on a single source and achieve a calibration closer to the world average. In the future, we may introduce some comparisons against “silver” cells, but that information will be communicated transparently in the metrology section of our extensive QC reports.
Reported LED lifetimes range from 10,000 to 100,000 hours depending on manufacturer and conditions. Most reported lifetimes are for LEDs driven at maximum current. We design our solar simulators to drive LEDs at lower currents, which results in the LEDs performing closer to the maximum of their lifetime range. Our solar simulators are rated for 10,000 hours and covered by a full two-year warranty.
The EQE module (only available with our Pico product) uses individual LEDs to probe a device’s spectral responsivity, and as such, the resolution of the resulting EQE curve is limited to the wavelengths of the LED types used in the solar simulator. While you won’t achieve nanometer resolution from our EQE module, you will get a low-resolution snapshot (between 25 nm to 100 nm on average) that still contains valuable device information.
The IV module is currently only available with the small area solar simulator, the Pico, but an IV module solution for the Sunbrick is currently on G2V’s product development roadmap. In the meantime, we recommend pairing Sunbricks with a source meter such as a Keithley 2400 series.
We make sure that our customers have access to resources that help them understand more not only about the products we offer, but relevant applications and standards.
