The photovoltaics of organic–inorganic lead halide perovskite materials have shown rapid
improvements in solar cell performance, surpassing the top efficiency of semiconductor …

The performance and stability of organic–inorganic hybrid perovskite solar cells (PSCs) is
sensitive to water and moisture in an ambient environment. Understanding how H2O …

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

The highest power conversion efficiencies (PCEs) reported for perovskite solar cells (PSCs)
with inverted planar structures are still inferior to those of PSCs with regular structures …

The unsatisfactory performance of low‐bandgap mixed tin (Sn)–lead (Pb) halide perovskite
subcells has been one of the major obstacles hindering the progress of the power …

We report on a new metal halide perovskite photovoltaic cell that exhibits both very high
solar-to-electric power-conversion efficiency and intense electroluminescence. We produce …

In lead halide perovskite solar cells, there is at least one recycling event of electron–hole
pair to photon to electron–hole pair at open circuit under solar illumination. This can lead to …

One of the greatest attributes of metal halide perovskite solar cells is their surprisingly low
loss in potential between bandgap and open-circuit voltage, despite the fact that they suffer …

Moisture, in the form of ambient humidity, has a significant impact on methylammonium lead
halide perovskite films. In particular, due to the hygroscopic nature of the methylammonium …

Under illumination of light-emitting diode (LED) or sunlight, the green color of all-inorganic
CsPbBr3 perovskite nanocrystals (CPB-NCs) often quickly changes to yellow, followed by …
