Compared with the n-i-p structure, inverted (p-i-n) perovskite solar cells (PSCs) promise increased operating stability, but these photovoltaic often exhibit lower power conversion efficiencies (PCEs) because of nonradiative recombination losses, particularly at perovskite/C60 interface. We passivated surface defects and enabled reflection minority carriers from interface into bulk using two types functional molecules. used sulfur-modified methylthio molecules to passivate suppress through strong coordination hydrogen bonding, along diammonium repel reduce contact-induced achieved field-effect passivation.

Judicious tailoring of the interface between SnO2 electron-transport layer and perovskite buried surface plays a pivotal role in obtaining highly efficient stable solar cells (PSCs). Herein, DL-carnitine hydrochloride (DL) is incorporated into perovskite/SnO2 to suppress defect-states density. A DL-dimer obtained at by an intermolecular esterification reaction. For film, Cl- can passivate oxygen vacancies (VO ) through electrostatic coupling, while N coordinate with Sn4+ Sn-related defects. FA+ defects via hydrogen bonding Pb-related more efficiently than DL monomer. Upon modification, interfacial are effectively passivated quality resultant film improved. As result, DL-treated device achieves gratifying open-circuit voltage (VOC 1.20 V champion power conversion efficiency (PCE) 25.24%, which record value among all reported FACsPbI3 PSCs date.

Abstract Surface–defect‐triggered non‐radiative charge recombination and poor stability have become the main roadblock to continued improvement in inorganic perovskite solar cells (PSCs). Herein, culprits are identified on surface by first‐principles calculations, purposefully design a brand‐new passivator, Boc‐S‐4‐methoxy‐benzyl‐l‐cysteine (BMBC), whose multiple Lewis‐based functional groups (NH, S CO) suppress halide vacancies coordinate with undercoordinated Pb 2+ through typical Lewis baseacid reactions. The tailored electron‐donating methoxyl group (CH 3 O–) can cause an increased electron density benzene ring, which strengthens interaction via electrostatic interactions. This BMBC passivation reduce trap density, enlarge grains, prolong lifetime, more suitable energy‐level alignment. In addition, hydrophobic tert‐butyl butoxycarbonyl (Boc‐) ensures that is uniformly covered prevents harmful aggregation steric repulsion at perovskite/hole–transporting layer (HTL) interface, thus providing umbrella resist moisture invasion. Consequently, combination of above increases efficiency CsPbI 3−x Br x PSC from 18.6% 21.8%, highest for this type metal PSCs so far, as far it known. Moreover, device exhibits higher environmental thermal stability.

Printable mesoscopic perovskite solar cells (p-MPSCs) do not require the added hole-transport layer needed in traditional p-n junctions but have also exhibited lower power conversion efficiencies of about 19%. We performed device simulation and carrier dynamics analysis to design a p-MPSC with mesoporous layers semiconducting titanium dioxide, insulating zirconium conducting carbon infiltrated that enabled three-dimensional injection photoexcited electrons into dioxide for collection at transparent conductor layer. Holes underwent long-distance diffusion toward back electrode, this separation reduced recombination contact. Nonradiative bulk dioxide/perovskite interface was by ammonium phosphate modification. The resulting p-MPSCs achieved efficiency 22.2% maintained 97% their initial after 750 hours maximum point tracking 55 ± 5°C.

Introducing fluorine (F) groups into a passivator plays an important role in enhancing the defect passivation effect for perovskite film, which is usually attributed to direct interaction of F and states. However, between electronegative electron-rich same molecule, may influence effect, ignored. We herein report that such interactions can vary electron cloud distribution around thus changing their coordination with sites. By comparing two fluorinated molecules, heptafluorobutylamine (HFBM) heptafluorobutyric acid (HFBA), we find F/-NH2 HFBM stronger than F/-COOH one HFBA, inducing weaker ability HFBA. Accordingly, HFBA-based solar cells (PSCs) provide efficiency 24.70 % excellent long-term stability. Moreover, large-area module (14.0 cm2 ) based on HFBA reaches 21.13 %. Our work offers insight understanding unaware group impacting film.
