Light can be produced and/or controlled electronically in a number of ways. Among the widely used of all the different types of semiconductor diodes are the Light Emitting Diodes or LEDs. It is a PN ...

LED lighting technology is increasingly adopted for its energy efficiency, durability, and longevity, making it an ideal solution for modernizing urban areas and developing smart city infrastructures.

Stacking light-generating layers in ‘tandem’ light-emitting diodes (LEDs) can enhance performance, but achieving efficient and stable tandem LEDs made with perovskite materials has remained a ...
