Abstract The power conversion efficiencies (PCEs) of polycrystalline perovskite (PVK) solar cells (SCs) (PC‐PeSCs) have rapidly increased. However, PC‐PeSCs are intrinsically unstable without encapsulation, and their efficiency drops during large‐scale production; these problems hinder the commercial viability PeSCs. Stability can be increased by using colloidal PVK nanocrystals (c‐PeNCs), which high surface strains, low defect density, exceptional crystal quality. use c‐PeNCs separates crystallization process from film formation process, is preponderant in fabrication. Consequently, has substantial potential to overcome challenges encountered when fabricating PC‐PeSCs. Research on nanocrystal‐based SCs (NC‐PeSCs) PCEs a level greater than those other quantum‐dot SCs, but not reached PC‐PeSCs; this inferiority significantly impedes widespread application NC‐PeSCs. This review first introduces distinctive properties c‐PeNCs, then strategies that been used achieve high‐efficiency Then it discusses detail persisting domain. Specifically, major solutions for NC‐PeSCs related short‐circuit current density J sc covered. Last, article presents perspective future research directions applications realm

Perovskite colloidal nanocrystals (PeNCs) have exceptional optoelectronic properties and phase stability, making them promising for photovoltaic applications. However, insulating ligands on PeNC surfaces limit the current density reduce power conversion efficiency (PCE) in solar cells (SCs). This study introduces an amine-assisted ligand-exchange (ALE) strategy using 3-phenyl-1-propylamine (3P1P) to effectively remove long from films. ALE reduced long-chain ligand without increasing number of defect states therefore exciton-binding energy FAPbI3 NC These changes facilitated exciton dissociation charge transport SCs. The facilitation was due increased magnetic dipole interaction between excitons after process. use achieved SCs that had improved short-circuit 17.98 mA/cm2 a PCE 15.56% with stability treatment negligible hysteresis. work provides new insight into engineering

Abstract Perovskite quantum dots (PQDs) show promise in light-emitting diodes (LEDs). However, near-infrared (NIR) LEDs employing PQDs exhibit inferior external efficiency related to the PQD emitting visible range. One fundamental issue arises from dynamic surface: ligand loss and ions migration interfacial sites serve as quenching centers, resulting trap-assisted recombination carrier loss. In this work, we developed a chemical treatment strategy eliminate interface achieve high utilization. We employ bidentate liquid agent (Formamidine thiocyanate, FASCN) with tight binding suppress formation of sites: FASCN-treated films fourfold higher energy than original oleate ligands. Furthermore, short ligands (carbon chain <3) enable treated eightfold conductivity; characteristics FASCN avoid use polar solvents guarantee better passivation. The conductivity ensures efficient charge transportation, enabling PQD-based NIR-LEDs have record-low voltage 1.6 V at 776 nm. champion EQE is ~23%: twofold control, represents highest among reported NIR-LEDs.
