Check out the ‘world’s first’ DC-to-DC solar-powered EV charger

Baua Electric

Photo: Enteligent California-based Enteligent is accepting pre-orders for what it claims is the world’s first DC-to-DC solar-powered EV charger. The solar EV charging tech company launched its product in February 2023 at Intersolar North America in Long Beach, California, and now it’s ready to take pre-orders.

Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

The prototype system is made up of three interconnected, new-generation, crystalline silicon solar cells attached to an electrolysis system that does not rely on rare metals. crystalline Silicon (c-Si) solar cells show high solar-to-electricity efficiencies, and have demonstrated stabilities in excess of 25 years.

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

showed for the first time how MEG allowed a solar cell to exceed 100% quantum efficiency by producing more electrons in the electrical current than the amount of photons entering the solar cell. A salt bridge connects the two compartments and transports H + and Na +. —Matthew Beard. —Yan et al. Click to enlarge.

OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”

Green Car Congress

The basic concept of the integrated solar battery is to use the contribution of the photovoltage to reduce greatly the charging overpotential caused by the difficulty in efficiently electrochemically decomposing lithium peroxide (Li 2 O 2 ), the discharge product formed on the oxygen electrode. —Yu et al. Photo-assisted charging. (a)

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

The traces are for solar cells of 7.7% Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. solar-to-fuels systems. illumination.

New plasma synthesis process for one-step conversion of CO2 and methane into higher value fuel and chemicals

Green Car Congress

Instead of using H 2 , direct conversion of CO 2 with CH 4 (dry reforming of methane, DRM) to liquid fuels and chemicals (e.g. The DBD reactor was connected to an AC high voltage power supply with a maximum peak voltage of 30 kV and a variable frequency of 7-12 kHz. In this work, the frequency was fixed at 9 kHz. Resources.
