Scientists from the Institute for Open and Transdisciplinary Research Initiatives at Osaka University discovered a new feature of solar cells made from antimony sulfiodide:sulfide composite they termed the wavelength-dependent photovoltaic effect (WDPE). The team determined that changing the color of incident light from visible to ultraviolet induced a reversible change in the […]
The exponentially increasing implementation of renewable energy systems, such as wind and solar energy, are urgently demanding the development of large-scale energy storage devices with flexibility, high energy conversion efficiency, and simple maintenance. Among diverse candidates, due to the natural abundance and low cost of sodium reserves, sodium-ion batteries (SIBs) have recently captured widespread […]
Engineers at the University of California San Diego have developed lithium-ion batteries that perform well at freezing cold and scorching hot temperatures, while packing a lot of energy. The researchers accomplished this feat by developing an electrolyte that is not only versatile and robust throughout a wide temperature range, but also compatible with a […]
The active layer morphology of organic solar cells (OSCs) serves as the bridge that connects material properties with device performances, and thus the morphology is of critical importance in device fabrication. State-of-the-art power conversion efficiencies (PCEs) of OSCs based on p-type donor polymers and n-type non-fullerene acceptors (NFAs) forming multi-length-scale fibril interpenetrating networks are […]
Researchers at The Hong Kong University of Science and Technology (HKUST) have developed a new hydrogen fuel cell which is not only the world’s most durable1 to date, but is also more cost-effective, paving way for a wider application of green energy in the pursuit of a carbon neutral world. Hydrogen fuel […]
An international collaboration led by Kobe University researchers has successfully developed a nanosheet-laminated photocatalytic (*1) membrane that demonstrates both excellent water permeance and photocatalytic activity. The membrane’s photocatalytic properties make it easier to clean as irradiating the membrane with light successfully reduces fouling (*2). They developed this membrane by laminating 2D nanomaterials (nanosheets (*3)) […]
