Considerable efforts are being made to advance inverted (p–i–n) perovskite solar cells
(PSCs). Several passivation and insulation strategies have effectively been applied to …

Perovskite solar cells have shown a strong increase in efficiency over the last 15 years. With
a record power conversion efficiency on small area above 34%, perovskite/silicon tandem …

This work discusses the need to enhance charge carrier collection to minimize halide
segregation in wide band-gap (WBG) perovskites. Here, we systematically elucidate the …

The characteristics of the soft component and the ionic‐electronic nature in all‐inorganic
CsPbI3‐xBrx perovskite typically lead to a significant number of halide vacancy defects and …

In recent years, perovskite has been widely adopted in series-connected monolithic tandem
solar cells (TSCs) to overcome the Shockley–Queisser limit of single-junction solar cells …

Three-dimensional/two-dimensional (3D/2D) heterojunctions in perovskite solar cells exhibit
excellent optoelectronic properties and enhanced stability under mild ageing conditions …

Preventing ion migration in perovskite photovoltaics is key to achieving stable and efficient
devices. The activation energy for ion migration is affected by the chemical environment …

Ion migration is a broad term used to account for the degradation of halide perovskite
materials and devices. However, ion mobility is only one piece of the full picture─ mobile …

Many recent advances in metal halide perovskite solar cell (PSC) performance are attributed
to surface treatments which passivate interfacial trap states, minimise charge recombination …

The migration of mobile ions through the metal halide perovskite layer is still one of the main
reasons for the poor stability of perovskite solar cells, LEDs, and photodetectors. To …
