Narrow bandgap mixed tin-lead perovskite solar cells (PSCs) have garnered substantial research interest owing to their remarkable optoelectronic properties. However, non-radiative recombination and carrier transport losses at the interface between layer charge (C60) significantly reduce overall efficiency of PSCs. To address this challenge, 9-Fluorenylmethyl carbazate (9FC) is incorporated C60. The hydrazide group present in 9FC effectively mitigates oxidation Sn2+. Furthermore, can engage chemical bonding with perovskite, while outward-facing aromatic rings create effective π-π interactions C60, thereby promoting enhanced interfacial transfer. highest-performing PSCs achieve a power conversion (PCE) 23.97%, accompanied by an impressive open-circuit voltage 0.91 V. Additionally, these facilitate development highly efficient two-terminal four-terminal all-perovskite tandem cells, which demonstrate efficiencies 27.01% 28.07%, respectively.

Tin perovskites are considered promising candidates for realizing high-performance, lead-free perovskite solar cells (PSCs). Despite prominent progress made through bulk optimization, unsatisfactory interfaces between tin and charge transport layers critical obstacles to boosting device performance. Herein, we address this issue by introducing piperazine dihydroiodide (PDI) ferrocene (Fc) at the interface of perovskite/C60 synergistically improve interfacial transport. Specifically, PD+ interacts with formamidinium ions (FA+) form an dipole, Fc establishes π-π conjugation C60. These effects significantly electron extraction reduce energy losses. As a result, efficiency PSCs is remarkably improved from 10.62% 13.65%, accompanied enhanced stability. This work highlights importance modulation in toward efficient eco-friendly photovoltaics.

Interface defects in perovskite solar cells (PSCs) can significantly impair device efficiency by promoting nonradiative recombination, hindering charge transport, and facilitating ion migration. In this work, we introduce a dual-interface passivation strategy utilizing 2-(N-morpholino)ethanesulfonic acid potassium (MESK) octylammonium iodide (OAI), targeting both the electron transport layer (ETL)/perovskite perovskite/hole (HTL) interfaces to enhance of wide-bandgap PSCs based on FA0.8Cs0.2Pb(I0.6Br0.4)3 with bandgap 1.77 eV. The sulfonic group MESK passivates bottom interface through coordination Pb ions, while amine OAI interacts halide ions effectively passivate top defects. improves crystallinity, enlarges grain size, reduces recombination.
