24/7 Power: Solar Cell and Supercapacitor Combo Solution
At the Daegu Gyeongbuk Institute of Science and Technology in South Korea, researchers have created a unique capacitor that is built right into the solar cell electronics. This innovation allows for the use of electricity generated by photovoltaic systems without needing to connect to a local power grid. This means that the solar energy can be used only when it’s needed. Additionally, the advanced capacitor has an impressive power density, enabling it to charge large batteries quickly.
Innovative Materials for Increased Performance
To achieve this, a specialized nickel foam is manufactured and enhanced with manganese, cobalt, copper, iron, and zinc. This combination leads to significant improvements in the conductivity and stability of the electrodes, achieving a high energy density of over 35 watt hours per kilogram. While this might seem low for a battery, it is approximately three times greater than what was seen in earlier tests for capacitors.
Exceptional Power Density and Longevity
A crucial feature of this supercapacitor is its power density, which is remarkably high at 2.5 kilowatts, and even reaches 12.3 kilowatts per kilogram in certain configurations. Moreover, the durability is impressive, with over 5,000 charging cycles recorded, where the remaining capacity was still 87.1%. Therefore, these ultracapacitors or supercapacitors have a longer lifespan when they experience less stress.
In certain tests, up to 100,000 cycles were achieved based on varying conditions. This indicates that the capacitor should easily support a photovoltaic system designed to last 20 to 25 years. However, due to typical voltage losses and gradual degradation, the efficiency remains slightly above 5%, which is much lower than that of standard solar cells.
Versatile Applications for Future Use
Despite the efficiency levels, there are numerous potential applications. For instance, off-grid usage is a possibility when electricity is required during periods of low sunlight. There is also the potential to provide stored energy during times of high electricity demand. Finally, the remarkable output capacity allows for the direct charging of large batteries using solar energy.

Plasma Reactor Creates Future Fuel with Zero CO₂ Emissions
The Haber-Bosch method is essential for modern farming, allowing for the mass production of ammonia. This process operates under high pressure and temperatures near 500°C, converting nitrogen, which is abundant in the atmosphere, into ammonia. It also generates hydrogen, usually sourced from fossil fuels.
Energy Usage and Environmental Impact
About 1% of the global energy use is linked to this ammonia production method, and its contribution to worldwide CO₂ emissions is even more significant. So far, the adverse effects on the environment from agriculture reliant on synthetic nitrogen fertilizers have not been discussed.
Rethinking Ammonia Production
It’s crucial to reevaluate this century-old process, as ammonia is vital for more than just agriculture. The molecule, made up of one nitrogen atom and three hydrogen atoms, can also be created through natural means.
Natural Processes of Ammonia Formation
In nature, light can break apart nitrogen in the air. Then, rain brings nitrogen oxides down to the ground and into the soil. There, bacteria and fungi transform them into ammonia with the aid of water, acting as a natural fertilizer, which is a key aspect of organic farming.
Researchers at the University of Buffalo in New York have designed a plasma reactor that replicates this natural method. It harnesses electricity from solar panels to turn air into plasma. A catalyst composed of copper and palladium triggers a reaction between nitrogen oxides and water to produce ammonia.
New Developments in Ammonia Production
Currently, this small test setup can create 1 gram of ammonia each day at room temperature, utilizing air without generating CO₂ emissions. Scientists are already developing a larger plasma reactor that could offer local and sustainable nitrogen fertilizer, especially in areas where traditional industrial production methods are not feasible.
Advantages of Ammonia Over Hydrogen
Additionally, ammonia is easier to store and use compared to hydrogen. It also boasts a much higher energy density per liter. Fuel cells designed for ammonia have been around for many years, and large-scale industrial storage systems have been experimented with for quite some time, despite not being completely safe. However, the same risks apply to hydrogen, oil, and natural gas.
