The surface of a semiconductor often has a key role in determining its properties. For metal
halide perovskites, understanding the surface features and their impact on the materials and …

Perovskite solar cells combine high carrier mobilities with long carrier lifetimes and high
radiative efficiencies. Despite this, full devices suffer from significant nonradiative …

In organic solar cells (OSCs), cathode interfacial materials are generally designed with
highly polar groups to increase the capability of lowering the work function of cathode …

Metal‐halide perovskites are rapidly emerging as an important class of photovoltaic
absorbers that may enable high‐performance solar cells at affordable cost. Thanks to the …

The efficiencies of perovskite solar cells have gone from single digits to a certified 22.1% in

Perovskite materials use earth-abundant elements, have low formation energies for
deposition and are compatible with roll-to-roll and other high-volume manufacturing …

A major bottleneck delaying the further commercialization of thin-film solar cells based on
hybrid organohalide lead perovskites is interface loss in state-of-the-art devices. We present …

Inverted perovskite solar cells (PSCs) with low‐temperature processed hole transporting
materials (HTMs) suffer from poor performance due to the inferior hole‐extraction capability …

In this work, significant suppression of the interfacial recombination by facile alkali chloride
interface modification of the NiOx hole transport layer in inverted planar perovskite solar …

The charge carrier dynamics in organic solar cells and organic–inorganic hybrid metal
halide perovskite solar cells, two leading technologies in thin‐film photovoltaics, are …
