Perovskite solar cells (PSCs) offer low costs and high power conversion efficiency. However, the lack of long-term stability, primarily stemming from interfacial defects susceptible metal electrodes, hinders their practical application. In past few years, two-dimensional (2D) materials (e.g., graphene its derivatives, transitional dichalcogenides, MXenes, black phosphorus) have been identified as a promising solution to solving these problems because dangling bond-free surfaces, layer-dependent electronic band structures, tunable functional groups, inherent compactness. Here, recent progress 2D material toward efficient stable PSCs is summarized, including role both interface electrodes. We discuss beneficial effects on perovskite growth, energy level alignment, defect passivation, well blocking external stimulus. particular, unique properties form van der Waals heterojunction at bottom are emphasized. Finally, perspectives further development using provided, such designing high-quality heterojunction, enhancing uniformity coverage nanosheets, developing new materials-based

The stability of perovskite solar cells (PSCs) has been considered as one the major obstacles toward practical application. Defects in layer and ion infiltration from hole transport (HTL) can trigger degradation n-i-p PSCs. Herein, phenylhydrazine-4-sulfonic acid (PHPA) was employed an additive to modulate crystallization during film formation, enlarging crystal grain sizes ∼3 μm. Density functional theory (DFT) calculations revealed that PHPA could effectively inhibit formation iodine vacancies (VI) passivate under-coordinated Pb2+ ions. Additionally, perfluorooctanoic (PFOA) adopted surface located dangling defects, improve hydrophobicity, Li+ migration HTL bottom perovskite, thus enhancing device's environmental operational stability. Consequently, resulting devices delivered a champion efficiency 25.1% with excellent maximum-power-point (MPP) tracking

Lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI) has been identified as the most used and effective p-dopant for hole transport layer (HTL) in perovskite solar cells (PSCs). However, migration agglomeration of Li-TFSI HTL negatively impact PSCs performance stability. Herein, we report an strategy adding a liquid crystal organic small molecule (LQ) into doped (2,2',7,7'-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'- spirobifluorene (Spiro-OMeTAD) HTL. It was found that introduction LQ Spiro-OMeTAD can efficiently enhance charge carrier extraction transportation device, which strongly retard recombination device. Consequently, efficiency is significantly enhanced to 24.42 % (Spiro-OMeTAD+LQ) from 21.03 (Spiro-OMeTAD).
