Figure 1: The evolution of perovskites. Figure 3: Structural diversity of the A-site and X-site ions of hybrid organic–inorganic perovskites. Concerns have been raised about the toxicity of Pb and Sn ...

IN the course of investigations on the reduction of metal halides by atomic hydrogen, using apparatus previously described 1,2, I have found that the halides of lithium, sodium, potassium and caesium ...

The conversion of solar energy into hydrogen energy represents a promising and green technique for addressing the energy shortage and reducing fossil fuel emissions. A research team from City ...

Solar energy is clean and abundant, but when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis. In photocatalytic water splitting, sunlight ...
