In recent years, researchers worldwide have been trying to develop solar cells and other technologies that can produce electrical energy from renewable sources, as these could reduce the emission of greenhouse gases and thus help to preserve life on our planet. Solar...
The oxygen evolution reaction (OER) is a chemical process that leads to the generation of molecular oxygen. This reaction is of key importance for the development of clean energy technologies, including water electrolyzers, regenerative fuel cells and rechargeable...
Recent technological advances have enabled the development of increasingly compact and flexible devices. This includes wearable or portable technology, such as smart watches, earphones or other smart accessories, which can assist human users in a variety of ways.
Over the past few decades, researchers worldwide have developed a growing amount of systems that can produce renewable energy, such as solar, wind or hydroelectric energy. While some companies and individuals have already started adopting these technologies, a...
Organic photovoltaics are a third-generation solar cell technology made of electron donor and electron acceptor materials instead of conventional semiconductor p-n junctions. The performance of this alternative solar cell technology has improved significantly over the...
Battery technology can sometimes be unstable and volatile, two characteristics that impair its safety and reliability. Actively monitoring the chemical and thermal state of battery cells over time could help to detect changes that may cause incidents or malfunctions,...
Rechargeable zinc metal batteries (RZMBs) could be a viable alternative to lithium ion batteries, which are currently used to power many types of electronic devices, as well as electric vehicles. Recent studies suggest that using optimized electrolytes could lead to...
Batteries with high energy densities could enable the creation of a wider range of electric vehicles, including flying vehicles that can transport humans in urban environments. Past studies predict that to support the operation of vehicles capable of take-off and...
Lithium (Li) batteries, or lithium metal batteries, use metallic lithium as an anode. Over the past few decades, rechargeable Li batteries have been used to power a wide variety of electronic devices, including toys, portable consumer devices and electric vehicles.
Solar cells made of semi-transparent photovoltaic (PV) materials typically have a fixed optical transmission, which results in either high transparency or high efficiency, but rarely both. In order to perform optimally when integrated on buildings, however, they...
