Lead halide perovskite solar cells now show excellent efficiencies and encouraging levels of
stability. Further improvements in performance require better control of the trap states which …

Sequential deposition has been widely employed to modulate the crystallization of
perovskite solar cells because it can avoid the formation of nucleation centers and even …

The performance of state‐of‐the‐art perovskite solar cells is currently limited by defect‐
induced recombination at interfaces between the perovskite and the electron and hole …

The power conversion efficiency (PCE) of tin perovskite solar cells is impeded by the
extremely poor resistance to oxidation and high density of intrinsic Sn vacancies. Herein, we …

Lead halide perovskite solar cells (PSCs) have advanced rapidly in performance over the
past decade. Single-crystal PSCs based on micrometers-thick grain-boundary-free films with …

High power conversion efficiencies (PCE), low energy payback time (EPBT), and low
manufacturing costs render perovskite solar cells (PSCs) competitive; however, a relatively …

So far, the combination of methylammonium bromide/methylammonium chloride
(MABr/MACl) or methylammonium iodide (MAI)/MACl is the most frequently used additives to …

Defect‐mediated carrier recombination at the interfaces between perovskite and
neighboring charge transport layers limits the efficiency of most state‐of‐the‐art perovskite …

Grain boundaries in lead halide perovskite films lead to increased recombination losses and
decreased device stability under illumination due to defect‐mediated ion migration. The …

Perovskite solar cells (PSCs) based on cesium (Cs)‐and rubidium (Rb)‐containing
perovskite films show highly reproducible performance; however, a fundamental …
