Every green leaf is able to convert solar energy into chemical energy, storing it in chemical compounds. However, an important sub-process of photosynthesis can already be technically imitated — solar hydrogen production: Sunlight generates a current in a so-called photoelectrode that can be used to split water molecules. This produces hydrogen, a versatile fuel that…
Space missions already use electric propulsion devices, where electromagnetic fields are utilized to generate the thrust of spacecraft. One such electrodeless device, which harnesses radio frequency (rf) to generate plasma and a magnetic nozzle (MN) to channel and accelerate plasma, has shown immense promise in pushing the boundaries of space travel. But scientists have so…
As low Earth orbit becomes more cluttered, it becomes increasingly necessary to use middle Earth orbits, and radiation-tolerant cell designs will be needed. Making photovoltaics thinner should increase their longevity because the charge carriers have less far to go during their shortened lifetimes. Scientists propose a radiation-tolerant photovoltaic cell design that features an ultrathin layer…

Dye-sensitized solar cells (DSSCs) are a promising next-generation solar power technology, but they suffer from dye aggregation on electrodes, which reduces charge carriers and the conversion efficiency. Fortunately, scientists have now found a simple way to prevent the aggregation by modifying the electrode’s surface with ionic liquids. Stable and eco-friendly, these versatile compounds demonstrate excellent…
