Organometal halide perovskite solar cells have evolved in an exponential manner in the two
key areas of efficiency and stability. The power conversion efficiency (PCE) reached 20.1 …

The interfacial atomic and electronic structures, charge transfer processes, and interface
engineering in perovskite solar cells are discussed in this review. An effective heterojunction …

The buried interface between the perovskite and the electron transport layer (ETL) plays a
vital role for the further improvement of power conversion efficiency (PCE) and stability of …

Here we report a solution-processing strategy to stabilize the perovskite-based
heterostructure. Strong Pb–Cl and Pb–O bonds formed between a [CH (NH2) 2] x [CH3NH3] …

Ion migration has been proposed as a possible cause of photovoltaic current–voltage
hysteresis in hybrid perovskite solar cells. A major objection to this hypothesis is that …

In this work, a SnO2/ZnO bilayered electron transporting layer (ETL) aimed to achieve low
energy loss and large open‐circuit voltage (Voc) for high‐efficiency all‐inorganic CsPbI2Br …

A synergic interface design is demonstrated for photostable inorganic mixed‐halide
perovskite solar cells (PVSCs) by applying an amino‐functionalized polymer (PN4N) as …

We report about the relationship between the morphology and luminescence properties of
methylammonium lead trihalide perovskite thin films. By tuning the average crystallite …

Organic–inorganic perovskites are a class of solution-processed semiconductors holding
promise for the realization of low-cost efficient solar cells and on-chip lasers. Despite the …

Abstract Perovskite Solar Cells (PSCs) have achieved power conversion efficiencies (PCEs)
comparable to established technologies, but their stability in real-life working conditions …
