Abstract Excess lead iodide (PbI 2 ), as a defect passivation material in perovskite films, contributes to the longer carrier lifetime and reduced halide vacancies for high‐efficiency solar cells. However, random distribution of excess PbI also leads accelerated degradation layer. Inspired by nanocrystal synthesis, here, universal ligand‐modulation technology is developed modulate shape films. By adding certain ligands, films with vertically distributed nanosheets between grain boundaries...
Localized surface plasmon resonance (LSPR) of doped Si nanocrystals (NCs) is critical to the development Si-based plasmonics. We now experimentally show that LSPR can be obtained from both B- and P-doped NCs in mid-infrared region. Both experiments calculations demonstrate Drude model used describe if dielectric screening carrier effective mass are considered. When doping levels B P similar, energy B-doped higher than because more efficiently activated produce free carriers NCs. find...
Hole transport layers (HTLs) play a crucial role in the efficiency and stability of perovskite solar cells (PSCs). The most efficient PSCs based on spiro-OMeTAD (Spiro) generally have problems. Here, NiOx/Spiro HTL has been designed implemented by combining advantages these two films. results indicated that device faster hole extraction ability better energy alignment than pure Spiro device, thus improving PCE from 19.8 to 21.66%. Compared with 60% initial Spiro-based devices, bilayer...
Chlorine incorporation and its configuration evolution during perovskite film formation were studied, as well effect on solar cell performance.
Interfacial engineering has been considered one of the most effective methods for further enhancing performance perovskite solar cells. Herein a facile but interfacial method modifying NiOx coated substrate by PTAA is demonstrated inverted planar The surface modification polymeric could effectively tailor quality absorber layer with larger grain size and better crystallinity controlling wettability varied thickness hydrophobic PTAA. improvement Jsc was ascribed to improved film reduced trap...
Abstract Surface passivation is increasingly one of the most prominent strategies to promote efficiency and stability perovskite solar cells (PSCs). However, molecules hinder carrier extraction due poorly conductive aggregation between surface transportation layer. Herein, a novel molecule: p ‐phenyl dimethylammonium iodide (PDMAI) with ammonium group on both terminals introduced, its effect systematically investigated. It found that PDMAI can mitigate defects at from hole transporting...
In this work, a hollow double-shelled architecture, based on n-type ZnIn2S4 nanosheet-coated p-type CuS octahedra (CuS@ZnIn2S4 HDSOs), is designed and fabricated as p-n heterojunction photocatalyst for selective CO2 photoreduction into CH4. The resulting hybrids provide rich active sites effective charge migration/separation to drive photoreduction, meanwhile, CO detachment delayed increase the possibility of eight-electron reactions CH4 production. As expected, optimized CuS@ZnIn2S4 HDSOs...
In this review, the morphology, composition and microstructure of buried interface are discussed, effective passivation strategies corresponding mechanisms summarized systematically.
High-quality MAPbI3 perovskite thin films were achieved conveniently utilizing the ultrasonic spray-coating method without an antisolvent process. Meanwhile, effect of self-assembled monolayers (SAMs), including 2PACz, MeO-2PACz, and Me-4PACz, on morphology, crystallization, optoelectronic properties layers was systematically investigated in solar cells (PSCs) with structure glass/ITO/NiOx/SAM/MAPbI3/PCBM/BCP/Ag. It is corroborated that introducing 2PACz MeO-2PACz can notably modulate growth...
Colloidal heavily doped silicon nanocrystals (Si NCs) exhibiting tunable localized surface plasmon resonance (LSPR) are of great interest in cost-effective, solution-processed optoelectronic devices given the abundance and nontoxicity Si. In this work we show that plasmonic properties colloidal stability without use ligands can be simultaneously obtained for Si NCs with boron (B). The B-doped NC colloids found to stable air months, opening up possibility device processing ambient atmosphere....
Perovskite/silicon tandem solar cells with high theoretical efficiency, low cost, and the potential for simple mass production have received significant attention. To maintain current matching, increasing open-circuit voltage (VOC) of top bottom subcells is an effective route to enhance efficiency (TSCs). In this paper, we focus on a strategy VOC simultaneously maintaining over 20%. Perovskite thin films added Cs in traditional FAMA cations shown large grain, smooth surface morphology, wider...
