Harnessing solar energy to transform reactions

Photochemistry is at the forefront of modern research and it requires precise control over the amount of light and type directed at your experiment. Failure to control these aspects places unreliable results regarding specific products and yields. Your research matters, it may range from photodissociation to photocatalytic cells, or one of the many niche areas in between requiring the visible spectrum

In your day-to-day life your equipment should work with you and not against you.

If you are still using traditional light sources then your equipment is working against you. The bulb lifetimes are short and they begin to dim which may not be noticeable to the human eye but it may impact your experiment’s results. In order to solve this problem you shut down your machine, change the bulb, recalibrate, and hope you can replicate the experiment again. Doing this every 1000 hours has become part of your routine and with it comes a loss of research time and issues with repeatability.

Can your research afford having downtime or unreliable results?

If not, we at G2V Optics can help.

Our Class AAA visible spectrum LED solar simulators are built from reliable technology with minimum moving parts, bulbs that last for >10,000 hours, controllable spectrum, and trusted by experts in Chemistry.

The right photons for reliable results.

What is your existing solar simulator costing you per month?

You place a lot of faith in your visible spectrum light source to ensure your research is accurate, valid, and repeatable. But have you ever looked at your total cost to own it? After all, with most scientific instruments there are ongoing costs that affect your budget later on. This makes choosing between underlying technologies and manufacturers a challenge. 

Do you pay less upfront and deal with the ongoing high costs? Or do you pay more now and save year over year? 

To help you with the research we explored the total cost of ownership for a solar simulator. Here are a few things we dive into:

Photoreforming microplastics in water through accurate sunlight

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.

Photochemical Testing FAQs

Absolutely! Many published academic articles report that visible-light photocatalysis is used for hydrogen evolution and oxygen evolution. LEDs have made great strides in extending their output deeper into the UV or IR wavelengths. However, the integration of deep-UV and longer-wavelength infrared wavelengths into LED solar simulators is still ongoing as technology becomes commercially viable.

Any area that requires visible or near visible light! The area of photochemistry is diverse and growing as we look to new technologies in renewables and sustainability. The central theme to all these new approaches revolves around the need of UV-vis light, specifically light that closely matches the sun’s spectra. After all, one of your key aspects of your research requires sunlight.

Here are some of the areas of photochemistry our solar simulators excel in: 

Photocatalytic microparticles, Photofragmentation, Photoluminescence, and photoelectrochemical research and applications.

More reproducibility: Our Pico solar simulator is designed to maintain exceptional output and stability over time. Standard lighting allows for unstable radiant flux that will 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. Having instability over time adds extra error to your results making them harder to reproduce. Using an LED 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 exceptional tunability 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.

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.

As with any lab, space is a vital commodity. Large and bulky equipment takes away from being able to do your work. Coming from a research background our pico footprint can fit on a small rolling cart. It also has the advantage of being lightweight meaning if it needs to be moved to make room for other bulky equipment it can be easily done.

As with any solar simulator, an increase in reactor temperature is expected as a function of intensity and light exposure time. A benefit of LED simulators is that they do not emit excess IR radiation so unwanted heating is reduced, which means the dominant reaction driver will be electron excitation and not thermal effects. However, LED power flux still causes some sample heating. Depending on the experimental conditions, this heating may be negligible.

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.

We understand the considerable investment that goes into buying a precision instrument. At G2V we want to partner with you at every step, from purchase decision to paper publication or product evolution.

Additionally, we are always ready to provide technical support, tips, recommendations, and other expertise to help you reach your scientific goals. In short, we don’t see your business as a one-time transaction; rather, we see you as a long term partner and are invested in your success.

Intensity and wavelength control gives you the ability to adjust the overall irradiance flux and emission wavelength channels allowing you to isolate those regions of the spectrum best-suited for your particular chemical reaction. Flexible control allows you to continue exploring new avenues of research in the visible light spectrum without the potential of needing a new instrument.

The Pico Python API (part of the optional Variable Spectra module) gives you the ability to integrate your simulator into your laboratory ecosystem. You can program your own ON/OFF routines, spectral profiles, and testing protocols in harmony with your other instruments and experimental protocols. Control your Pico simulator manually or from a script!
For those experiments requiring controlled environments, you can connect your simulator to LAN or Wi-Fi networks and control it from the comfort of a web browser – no need to install software. Operate your simulator from the lab bench or from your office next door.
