A myriad of studies and strategies have already been devoted to improving the stability perovskite films; however, role different crystal facets in is still unknown. Here, we reveal underlying mechanisms facet-dependent degradation formamidinium lead iodide (FAPbI3) films. We show that (100) facet substantially more vulnerable moisture-induced than (111) facet. With combined experimental theoretical studies, are revealed; a strong water adhesion following an elongated lead-iodine (Pb-I) bond distance observed, which leads δ-phase transition on Through engineering, higher surface fraction can be achieved, (111)-dominated crystalline FAPbI3 films exceptional against moisture. Our findings elucidate unknown kinetics.

Rationalization of passivation strategies toward high-performance perovskite solar cells

Chemical Society Reviews, Год журнала: 2022, Номер 52(1), С. 163 - 195

Опубликована: Дек. 1, 2022

Lead halide perovskite solar cells (PSCs) have shown unprecedented development in efficiency and progressed relentlessly improving stability. All the achievements been accompanied by diverse passivation strategies to circumvent pervasive defects materials, which play crucial roles process of charge recombination, ion migration, component degradation. Among tremendous efforts made solve these issues achieve high-performance PSCs, we classify review both well-established burgeoning provide further guidance for protocols including chemical eliminate formation bonds, physical strain relaxation or treatments, energetic improve stability toward light oxygen, field-effect regulate interfacial carrier behavior. The subtle but non-trivial consequences from various need advanced characterization techniques combining synchrotron-based X-ray analysis, capacitance-based measurements, spatially resolved imaging, fluorescent molecular probe, Kelvin probe force microscope, etc., scrutinize mechanisms. In end, challenges prospective research directions on advancing are proposed. Judicious combinations among chemical, physical, energetic, deserve more attention future high-efficiency stable photovoltaics.

Lead-chelating hole-transport layers for efficient and stable perovskite minimodules

Science, Год журнала: 2023, Номер 380(6647), С. 823 - 829

Опубликована: Май 25, 2023

The defective bottom interfaces of perovskites and hole-transport layers (HTLs) limit the performance p-i-n structure perovskite solar cells. We report that addition lead chelation molecules into HTLs can strongly interact with lead(II) ion (Pb 2+ ), resulting in a reduced amorphous region near passivated surface. minimodule an aperture area 26.9 square centimeters has power conversion efficiency (PCE) 21.8% (stabilized at 21.1%) is certified by National Renewable Energy Laboratory (NREL), which corresponds to minimal small-cell 24.6% 24.1%) throughout module area. Small-area cells large-area minimodules had light soaking stability 3010 2130 hours, respectively, loss 10% from initial value under 1-sun illumination open-circuit voltage conditions.
