Abstract Quasi-two-dimensional (quasi-2D) Ruddlesden–Popper (RP) perovskites such as
BA2Cs n–1Pb n Br3 n+ 1 (BA= butylammonium, n> 1) are promising emitters, but their …

Blue perovskite light-emitting diodes (PeLEDs) are essential in pixels of perovskite displays,
while their progress lags far behind their red and green counterparts. Here, we focus on …

Photovoltaic solar cells based on metal-halide perovskites have gained considerable
attention over the past decade because of their potentially low production cost, earth …

The technological evolution has been progressing for centuries and will possibly increase at
a higher rate in the 21st century. Currently, in this age of nanotechnology, the discovery of …

Serious performance decline arose for perovskite light-emitting diodes (PeLEDs) once the
active area was enlarged. Here we investigate the failure mechanism of the widespread …
