Lead-free tin halide perovskite solar cells (TPSCs) have driven much research attention for their environmental friendliness. However, the low efficiency and large open-circuit voltage (Voc) deficit limit further development. Here, we introduced a π-conjugated Lewis base, 1H-pyrrolo[2,3-b]pyridin-6-ylaamine (1H6An), N donor unique electron-donating role of pyridine pyrrole with unpaired lone pair electrons to interact perovskites thus retard oxidation Sn2+ during aging process precursors. Meanwhile, interaction stabilized lattice decreased microstrain deposited films. The carrier kinetics revealed notably enhanced extraction transport as well nonradiative recombination 1H6An. Consequently, this approach delivered an 13.28% remarkable Voc enhancement from 853 907 mV. 1H6An device exhibited extended lifespan over 2500 h around 90% retention its initial value in N2 atmosphere.

Adhesion‐Controlled Heterogeneous Nucleation of Tin Halide Perovskites for Eco‐Friendly Indoor Photovoltaics

Advanced Materials, Год журнала: 2024, Номер unknown

Опубликована: Июль 16, 2024

Abstract The rapid development of the Internet Things (IoT) has accelerated advancement indoor photovoltaics (IPVs) that directly power wireless IoT devices. interest in lead‐free perovskites for IPVs stems from their similar optoelectronic properties to high‐performance lead halide perovskites, but without concerns about toxic leakage environments. However, currently prevalent perovskite IPVs, especially tin (THPs), still exhibit inferior performance, arising uncontrollable crystallization. Here, a novel adhesive bonding strategy is proposed precisely regulating heterogeneous nucleation kinetics THPs by introducing alkali metal fluorides. These ionic adhesives boost work adhesion at buried interface between substrates and film, subsequently reducing contact angle energy barrier nucleation, resulting high‐quality THP films. solar cells achieve an efficiency 20.12% under illumination 1000 lux, exceeding all types successfully powering radio frequency identification‐based sensors.

Abstract Tin‐based perovskite solar cells (TPSCs) have received increasing attention due to their low toxicity, high theoretical efficiency, and potential applications as wearable devices. However, the inherent fast uncontrollable crystallization process of tin‐based perovskites results in defect density film. Meanwhile, when fabricated into flexible devices, prepared film exhibits inevitable brittleness Young's modulus, seriously weakening mechanical stability. In this work, we design synthesize a cross‐linkable fullerene, thioctic acid functionalized C 60 fulleropyrrolidinium iodide (FTAI), which has multiple interactions with components can finely regulate quality The obtained shows an increased grain size more matched energy level electron transport material, effectively improving carrier extraction efficiency. FTAI‐based rigid device achieves champion efficiency 14.91 % enhanced More importantly, FTAI located at boundaries could spontaneously cross‐link during annealing process, improves conductivity elasticity boundaries, thereby giving excellent bending resistance. Finally, yields record 12.35 displays robust durability, retaining about 90 initial after 10,000 times.

Tin halide perovskites are promising candidates for lead-free perovskite solar cells due to their ideal bandgap and high charge-carrier mobility. However, poor crystal quality rapid degradation in ambient conditions severely limit stability practical applications. This study demonstrates that incorporating UiO-66, a zirconium-based MOF, significantly enhances the performance of tin (TPSCs). The unique porous structure abundant carboxylate groups UiO-66 improve crystallinity film FASnI₃, reduce defect density, prolong charge carrier lifetimes. Consequently, power conversion efficiency (PCE) UiO-66-integrated TPSCs increases from 11.43% 12.64%, devices maintain over 90% initial PCE after 100 days nitrogen glovebox. These findings highlight potential addressing challenges perovskites.
