Engineered Sunlight to Drive Chemical Innovation
If you’re running photocatalysis, water splitting, or photochemical synthesis using a Xenon-based light source, you’re likely introducing hidden variables into your experiment without realizing it.
Xenon arc lamps were never designed for quantitative chemical validation they were a workaround developed in an earlier era of photochemistry. Their spectral drift, warm-up dependence, and aging behavior can introduce inconsistencies that quietly propagate through your reaction data. What appears as a change in catalytic activity, quantum efficiency, or reaction rate may already be influenced by instability in the light source itself.
As photochemical systems become more advanced and research shifts toward mechanism-driven studies, solar fuel generation, and high-precision catalyst benchmarking, these hidden limitations start to matter more. Small deviations in irradiance, wavelength distribution, or temporal stability can translate into significant uncertainties in hydrogen evolution rates, CO₂ reduction efficiency, apparent quantum yield (AQE), and reaction kinetics. This becomes especially critical when comparing materials, optimizing photocatalysts, or publishing reproducible results. In that context, the limitation is no longer just the hardware, it’s the confidence you can place in your data. What was once acceptable as a practical solution has now become a bottleneck for truly controlled, repeatable, and mechanism-driven photochemistry.
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.
reproduce sunlight
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.
In all of these, light is a controlled input parameter, not just a condition. That means:
Without control, reproducibility breaks down.
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.
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.
