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

The stabilization of grain boundaries and surfaces of the perovskite layer is critical to extend
the durability of perovskite solar cells. Here we introduced a sulfonium-based molecule …

Defects in perovskite are key factors in limiting the photovoltaic performance and stability of
perovskite solar cells (PSCs). Generally, choline halide (ChX) can effectively passivate …

Grain boundaries (GBs) in perovskite polycrystalline films are the most sensitive place for
the formation of the defect states and the accumulation of impurities. Thus, abundant works …

Although the power conversion efficiency values of perovskite solar cells continue to be
refreshed, it is still far from the theoretical Shockley-Queisser limit. Two major issues need to …

Mixed‐halide perovskites show tunable emission wavelength across the visible‐light range,
with optimum control of the light color. However, color stability remains limited due to the …

Due to the unpredictable composition and vulnerable nature of the grain boundaries (GBs),
grain boundaries engineering with improving the order degree of perovskite GBs would be …

The efficiency and longevity of metal-halide perovskite solar cells are typically dictated by
nonradiative defect-mediated charge recombination. In this work, we demonstrate a vapor …

The efficiency of perovskite solar cells (PSCs) is hindered by substantial defects within the
grain boundaries (GBs) of polycrystalline perovskite films. Conventional post‐treatment …

Despite the outstanding power conversion efficiency (PCE) of perovskite solar cells (PSCs)
achieved over the years, unsatisfactory stability and lead toxicity remain obstacles that limit …
