Suppressing nucleation over large areas Although formamidinium-based lead iodide (PbI 2 ) perovskites have a favorable bandgap and good thermal stability, the difficulty in controlling makes it difficult to grow high-quality, large-area films compared with methylammonium counterparts. Bu et al. show that adding N -methyl-2-pyrrolidone perovskite precursors forms an adduct PbI promotes formation of desired black α-phase at room temperature. The addition potassium hexafluorophosphate...
Abstract NiO x hole transporting layer has been extensively studied in optoelectronic devices. In this paper, the low temperature, solution–combustion‐based method is employed to prepare layer. The resulting thin films show better quality and preferable energy alignment with perovskite film compared high temperature sol–gel‐processed . With this, high‐performance solar cells are fabricated successfully power conversion efficiency exceeding 20% using a modified two‐step prepared MA 1− y FA...
Abstract Among all inorganic halide perovskite photovoltaic materials, CsPbIBr 2 exhibits the most balanced features in terms of bandgap and stability. However, poor quality solution‐processed films impedes further optimization cells performance. Herein, a facile intermolecular exchange strategy for film is demonstrated, wherein an optimized methanol solution CsI spin‐coated on precursor conventional one‐step route. It surprisingly produces full‐coverage pure‐phase featured with average...
Perovskite solar cells (PSCs) have been attracting considerable attention because of their low fabrication cost and impressive energy conversion efficiency. Most PSCs are built on transparent conductive oxides (TCOs) such as fluorine-doped tin oxide (FTO) or indium (ITO), which costly rigid. Therefore, it is significant to explore alternative materials the electrode PSCs. In this study, highly poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PSS) films were investigated both rigid...
Recent research shows that the interface state in perovskite solar cells is main factor which affects stability and performance of device, engineering including strain an effective method to solve this issue. In work, a CsBr buffer layer inserted between NiO x hole transport relieve lattice mismatch induced stress induce more ordered crystal growth. The experimental theoretical results show addition optimizes absorber layer, reduces defects traps, enhances extraction/transfer. power...
Perovskite solar cells (PSCs) are considered as a promising photovoltaic technology due to their high efficiency and low cost. However, long-term stability, mechanical durability, environmental risks still unable meet practical needs. To overcome these issues, we designed multifunctional elastomer with abundant hydrogen bonds carbonyl groups. The chemical bonding between polymer perovskite could increase the growth activation energy of film promote preferential high-quality film. Owing...
Abstract The ionic nature endows halide perovskites with intrinsic interfacial defects in the formed polycrystalline films, thus imposing challenge of synchronously passivating these low formation energies that directly account for unsatisfied performance perovskite solar cells (PSCs). By virtue theoretically proven capability a three to four times enhancement energy each defect Pb‐I antisite (Pb I ) and iodine vacancy (V ), new passivation molecule 1,10‐phenanthrolin‐5‐amine (PAA) is...

Rationally managing the secondary-phase excess lead iodide (PbI2 ) in hybrid perovskite is of significance for pursuing high performance solar cells (PSCs), while challenge remains on its conversion to a homogeneous layer that robust stable against environmental stimuli. We herein demonstrate an effective strategy surface reconstruction converts PbI2 into gradient sulfate-silica bi-layer, which substantially stabilizes film and reduces interfacial charge transfer barrier PSCs device. The...

One of the primary challenges in commercializing perovskite solar cells (PSCs) is achieving both high power conversion efficiency (PCE) and sufficient stability. We integrate wafer-scale continuous monolayer MoS 2 buffers at top bottom a layer through transfer process. These films physically block ion migration into carrier transport layers chemically stabilize formamidinium lead iodide phase strong coordination interaction. Effective chemical passivation results from formation Pb-S bonds,...

A slot-die coating technique is used for the crystal alignment of triisopropylsilylethynyl (TIPS)-pentacene in solution-processed field-effect transistors (FETs). The film thickness, uniformity, and growth behavior are well controlled by tuning parameters using a mixed solvent system (toluene/anisole).

Perovskite CsPbIBr2 is attracting ever-increasing attention for carbon-based, all-inorganic solar cells, owing to its well-balanced band gap and stability features. However, significant interfacial recombination of charge carriers in cells fabricated with this active layer, which intrinsically associated the unwanted conduction misalignment between commonly used TiO2 electron transport has limited power conversion efficiency (PCE) values. Herein, we demonstrate successful alignment...
