Japanese scientists have built a chalcopyrite PV device for tandem solar cells and water splitting for hydrogen generation. The device has a power conversion efficiency of 11.05%, an open-circuit ...

Artificial photosynthesis provides a way to store solar energy in chemical bonds. Achieving water splitting without an applied external potential bias provides the key to artificial photosynthetic ...

Researchers in the Netherlands have designed a water-splitting system with an electrochemical cell and a 25%-efficient tandem perovskite-silicon solar cell. It can reportedly achieve a ...

Turning away from fossil fuels is necessary if we are to avert an environmental crisis due to global warming. Both industry and academia have been focusing heavily on hydrogen as a feasible clean ...

The photoelectrochemical (PEC) overall water-splitting reaction (OWS) has been fully developed in the past decade, especially in the new catalysts, characterization methods and reaction mechanisms.

Researchers have developed a novel device that produces oxygen inside of a 'living pharmacy' implant in order to keep cells alive inside the self-contained device. The device produses oxygen through a ...

Scientists combine two promising photocatalysts to obtain higher solar-to-hydrogen conversion efficiency and durability in a water splitting cell. Turning away from fossil fuels is necessary if we are ...
