Perovskite materials have outstanding optical and electronic properties. In recent years, the
power conversion efficiency (PCE) of perovskite solar cells (PSCs) in the laboratory has …

Perovskite solar cells (PSCs) are undergoing rapid development and the power conversion
efficiency reaches 25.7% which attracts increasing attention on their commercialization …

Owing to their insufficient light absorption and charge transport, 2D Ruddlesden–Popper
(RP) perovskites show relatively low efficiency. In this work, methylammonium (MA) …

Understanding the function of moisture on perovskite is challenging since the random
environmental moisture strongly disturbs the perovskite structure. Here, we develop various …

Perovskite solar cells (PSCs) have drawn unprecedented attention due to their skyrocketing
power conversion; however, their reported fill factors (FFs) still lag behind those of …

Interfacial trap-assisted non-radiative recombination and residual stress impede the further
increase of power conversion efficiency (PCE) and stability of the methylammonium-free …

The existence of a defective area composed of nanocrystals and amorphous phases on a
perovskite film inevitably causes nonradiative charge recombination and structural …

Solar cells based on metal halide perovskites have reached a power conversion efficiency
as high as 25%. Their booming efficiency, feasible processability, and good compatibility …

Halide perovskite semiconductors with extraordinary optoelectronic properties have been
fascinatedly studied. Halide perovskite nanocrystals, single crystals, and thin films have …

Constructing 2D/3D perovskite heterojunctions is effective for the surface passivation of
perovskite solar cells (PSCs). However, previous reports that studying perovskite post …
