Lead halide perovskites of the type APbX3 (where A= methylammonium MA, formamidinium
FA, or cesium and X= iodide and bromide), in a single‐crystal form or more often as …

The perovskite photovoltaic field has developed rapidly within a decade. In particular,
formamidinium (FA)‐rich perovskite allows a broad absorption spectrum, and is considered …

SnO2 is widely used and one of the most efficient electron transport layers in perovskite
solar cells (PSCs). However, SnO2 films often contain detrimental defects and may also …

An electron‐transport layer (ETL) with appropriate energy alignment and enhanced charge
transfer is critical for perovskite solar cells (PSCs). However, interfacial energy level …

Additive engineering is one of the most efficient approaches to improve not only photovoltaic
performance but also phase stability of formamidinium (FA)‐based perovskite. Chlorine …

Fabrication of high-quality perovskite films with a large grain size and fewer defects is
always crucial to achieve efficient and stable perovskite solar cells (PSCs). Here, we report a …

Interfacial passivation has been considered as an effective strategy to improve the
performance of perovskite solar cells (PSCs) by modifying defect trap states between …

Hole transport layers (HTLs) play a crucial role in the efficiency and stability of perovskite
solar cells (PSCs). The most efficient PSCs based on spiro-OMeTAD (Spiro) generally have …

The organic–inorganic hybrid perovskite solar cells (PSCs) achieve relatively high power
conversion efficiencies (PCEs) over the past few years. However, defects on the surface and …

Perovskite solar cells are among the highly efficient devices with a power conversion
efficiency of over 25% due to their outstanding optoelectronic properties like bandgap …
