In the last half of the 1960s, new high-intensity discharge light sources based on a halogen cycle have made considerable impact on the lighting market. Such light sources depend on the volatilization ...

Rashba spin–orbit splitting in metal halide perovskites has been widely associated with a direct-to-indirect bandgap transition, a mechanism often proposed to suppress nonradiative recombination and ...

High intensity discharge (HID) lamps are the most suitable when both high light power levels and good color rendering are researched. Some remarkable theoretical advantages would be obtained if these ...

The past 2 years have seen the uniquely rapid emergence of a new class of solar cell based on mixed organic–inorganic halide perovskite. Grain boundaries are present in polycrystalline thin film solar ...
