The performance and stability of metal halide perovskite solar cells strongly depend on
precursor materials and deposition methods adopted during the perovskite layer …

The mixtures of cations and anions used in hybrid halide perovskites for high-performance
solar cells often undergo element and phase segregation, which limits device lifetime. We …

Metal halide perovskite based tandem solar cells are promising to achieve power
conversion efficiency beyond the theoretical limit of their single‐junction counterparts …

Abstract Wide‐bandgap (WBG,≈ 1.8 eV) perovskite is a crucial component to pair with
narrow‐bandgap perovskite in low‐cost monolithic all‐perovskite tandem solar cells …

We show that adding ethylenediamine (EDA) to perovskite precursor solutions improves the
photovoltaic device performance and material stability of high-bromide-content …

Metal halide perovskite single crystals (MHP‐SCs) are known for their facile fabrication into
large sizes using inexpensive solution methods. Owing to their combination of large mobility …

Formamidinium lead trioiodide (FAPbI3) is a promising perovskite for single-junction solar
cells. However, FAPbI3 is metastable at room temperature and can cause intrinsic quantum …

The growing demand for renewable energy has spotlighted photovoltaics (PVs), particularly
perovskite solar cells (PSCs). However, current processes for manufacturing PSCs rely on …

The response of an oxide crystal to the atmosphere can be personified as breathing─ a
dynamic equilibrium between O2 gas and O2–anions in the solid. We characterize the …
