They have improved a process for vertically depositing a solution made from an inexpensive perovskite solute onto a moving substrate below. Not only have they discovered the crucial role played by one of the solvents used, but they have also taken a closer look at the aging and storage properties of the solution. […]
Scientists have demonstrated that modifying the topmost layer of atoms on the surface of electrodes can have a remarkable impact on the activity of solar water splitting. As they reported in Nature Energy on Feb. 18, bismuth vanadate electrodes with more bismuth on the surface (relative to vanadium) generate higher amounts of electrical current […]
The German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) is conducting research into new materials for more powerful batteries and fuel cells. DLR scientists are now using a quantum computer to simulate electrochemical processes within energy storage systems. This makes it possible to design the materials used in such a way that […]
Scientists at The University of Manchester have found a way to accelerate the uptake of solar technology, by increasing the environmental safety of perovskite solar cells. Perovskite solar cells have attracted interest because, unlike silicon solar cells, they can be mass produced through roll-to-roll processing. Additionally, they are light and colourful, with […]
A considerable portion of the efforts to realize a sustainable world has gone into developing hydrogen fuel cells so that a hydrogen economy can be achieved. Fuel cells have distinctive advantages: high energy-conversion efficiencies (up to 70%) and a clean by-product, water. In the past decade, anion exchange membrane fuel cells (AEMFC), […]
A research team in Korea has developed a ceramic fuel cell that offers both stability and high performance while reducing the required amount of catalyst by a factor of 20. The application range for ceramic fuel cells, which have so far only been used for large-scale power generation due to the difficulties associated with […]
