Engineered Sunlight to Drive Chemical Innovation
Sunlight is a virtually limitless source of sustainable energy. Its absorption by substances to drive photochemical reactions is at the forefront of modern chemistry research.
Whether you are working on photodissociation to break down waste materials, designing novel catalysts to convert and store solar energy in chemical fuels, studying photocatalytic behavior of bacterial fuel cells, characterizing light-driven changes in molecular structures, optimizing photo-assisted redox reactions, pursuing photosynthesis of novel nanomaterials, photoreforming compounds into value-added materials, or testing the performance of a bacterial cell, photons are the inexpensive and abundant “traceless reagent” of the future.
Photochemistry is a precise science requiring high control over a reaction’s amount and type of input light since these variables sensitively determine specific products and yields. Traditional light sources, with short bulb lifetimes that lead to dimming or flickering, simply do not have sufficient reliability for reproducible results. They also lack the tunability to test isolated facets of an experiment.
G2V’s Class AAA LED solar simulators are built from reliable technology made to last, engineered to give you absolute spectral control for your unique experimental needs.
The right photons for the right reaction.
You’re building something great. Our solar replication technologies mean you don’t have to worry about accurate light.
How many times have you been stuck failing to reproduce an experiment? How many times has instrumental variance resulted in lost time or unreliable results? The Pico is carefully designed for photon production as reliable as the sun. This means you can spend your valuable time studying the chemistry of your reactions instead of wrangling the performance of your instrument. The Pico enables you to precisely probe photon-matter interactions with ease and confidence.
Are you ready to scale up your surface-to-photon ratio? Ready to move up from batch to flow chemistry? Need to illuminate a bigger reactor or run several experiments in parallel? The large-area Sunbrick solar simulator is the instrument of choice to take your chemistry to the next level.
Additionally, its modular, tileable design enables you to build the solar setup best-suited for your needs, whether that’s wide-area or high-irradiance testing. Contact us to discuss how the Sunbrick can unlock a new dimension of chemical innovation.
Problem: A chemistry research group was looking to photoreform microplastic-rich water waste into hydrogen and useful side products. They wanted to test the effect of their latest catalyst candidate on reaction behavior under standard sunlight conditions.
Innovation: The G2V Pico small-area LED simulator provided light that accurately matches the sun’s irradiance on Earth.
Outcome: The researchers were able to systematically study different aspects of their catalyst. By adjusting the intensity, they were able to calculate the overall reaction rate. By adjusting the Pico’s channel output they narrowed wavelength regions that experienced higher absorbance and that favoured the formation of certain products. Finally, using the One-Click Sun (beta) feature of the optional Variable Spectra module, they simulated the behavior that their reaction would have at higher altitudes and in places close to the equator in order to better understand real-world performance.
You’re building the future. We’ll provide the light.
Buying a solar simulator is a considerable investment that goes beyond the initial purchase. Choosing between underlying technologies and manufacturers can be a challenge. In this article we highlight what to look for beyond the sticker price.
We explore costs like operation and maintenance, and discuss the added value of owning a simulator that is easy to use with multiple complementary features.

Looking for additional resources on the importance of using a high-quality simulator for photochemical research and to improve the quality of your published research? This Nature article provides an excellent overview of the role that solar simulation and reactor design play on reaction kinetics.
High-quality LED solar simulators remove the uncertainties associated with using an unreliable light source. G2V’s class AAA LED simulators are designed to maintain exceptional output and stability, which means the irradiance flux will not vary or drift throughout your experiment. That means you’ll get stable, more consistent reaction products and yields.
Many reactions also depend on the total absorbed energy, meaning many required hours of light exposure for a reaction to reach completion. Using an LED-driven simulator gives you confidence that the results of your reactions are attributable to the chemical mechanisms and not to light variance.
The bandgap properties of materials determine what photons are absorbed. Excess emission peaks such as those generated by arc discharge in bulb-based solar simulators are not representative of real sunlight, and may vary between instruments. These large spectral deviations can lead to unrealistic variations in absorbance that reduce the accuracy of a chemical reaction’s results. A faithful spectral output helps ensure that similar conditions result in comparable results between different labs and instruments.
Want to know how your catalysts would respond to Dubai’s July midday sun or London’s early winter morning? One-Click Sun (beta) replicates the solar irradiance of any place on Earth at any time of day throughout the year, giving you a more realistic prediction of reaction behaviours in their target application environments.
More reproducibility: Our Pico solar simulator is designed to maintain exceptional output and stability throughout its operation. This means that the irradiance flux will not vary or drift throughout your experiment and affect your reaction products and yields. Many reactions also depend on the total energy flux, thus many hours of exposure may be necessary for a reaction to reach completion. Using an LED-driven simulator gives you confidence that the results of your reactions are attributable to the chemical mechanisms and not to light variance.
High accuracy and compact design: Engineered to simulate the irradiance profile of the sun with high accuracy, the Pico is a compact solution that provides the right photons from a benchtop-sized workhorse.
Variable spectrum: Our Pico simulator may include an optional Variable Spectra module that lets you adjust its output channels so that you can probe the absorbance of your materials to different regions of the wavelength spectrum. The Variable Spectra module lets you unlock these deeper catalytic observations from your same trusted device.
