Abstract Wide‐bandgap (WBG) perovskite solar cells (PSC) have been widely applied in tandem photovoltaics (PV) for various scenarios including indoor, building, and underwater PV. However, the current mainstream WBG PSCs are fabricated by spin‐coating, which is inappropriate scalable production. Blade‐coating has demonstrated great potential to realize commercial PV panel size at low cost, while till present, only a few efforts devoted blade‐coated PSCs, significantly hampering their efficiency evolvements. Herein, state‐of‐the‐art research progress major challenges of reviewed, with optimization strategies being summarized into four main categories, such as blading parameter, solvent engineering, additive/dopant, defect passivation. Film homogenization, manipulation, optimized blade coating machines, single‐halide three‐dimensional perovskites, fabrication on textured substrate proposed five promising directions future investigations high‐performance PSCs.

The buried interface is pivotal for enhancing both the efficiency and stability of p-i-n perovskite solar cells (PSCs). This because carrier extraction recombination processes can be significantly affected by defects that tend to form on bottom side. Herein, a dual-reaction site molecule homopiperazine-1,4-bis (2-ethanesulfonic acid) (HEA) employed as an effective multifunctional passivator self-assembled monolayer (SAM)/perovskite inverted PSCs.

Methylammonium chloride (MACl) additive is almost irreplaceable in high-performance formamidinium (FA) perovskite photovoltaics. However, the byproduct of methyl (MFA+) from reaction MA0 and FA damages compositional purity phase stability α-FAPbI3.

ABSTRACT The employment of rationally designed functional group‐bearing molecules as additives to passivate perovskite defects has emerged a prevalent trend. Among the diverse array passivation materials, donor‐π‐acceptor (D‐π‐A) structured have attracted widespread attention due their unique ability simultaneously regulate electron donor and acceptor units, thereby promoting coordination with undercoordinated ions films. In this work, we introduce an indoline‐based D‐π‐A molecule (labeled IHT) efficient passivator for solar cells (PSCs). extraordinary electron‐donating capability indoline moiety endows electron‐withdrawing cyanoacetic acid group elevated density, which is in favor interaction under‐coordinated Pb 2+ lattice, thus reducing density defective states within Experimental outcomes underscore efficacy IHT additive passivating CsFA‐based PSCs. optimal devices demonstrate remarkable champion photovoltaic conversion efficiency 21.25%, notable improvement 7.4% compared Cs‐FA‐PbI 3 devices. stability assessments reveal that unencapsulated IHT‐treated retained 83% initial after 30 days ambient air, whereas untreated exhibited decline 54% under same condition.

Abstract Controllable solution-based synthesis of semiconducting micro-structured materials with tailored morphologies and specific properties is crucial for the development cost-effective microelectronic devices. Here, we present a high-throughput experimental approach that integrates in-situ absorption spectroscopy molecular dynamics simulations to systematically explore ligand-mediated crystallization in two-dimensional (2D) perovskite single crystals. We establish clear correlation between structures organic ligands morphology crystals, showing shorter promote 1D nanowire formation, while longer favor 2D nanosheet growth. In-situ reveal larger induce conformational changes within lattice, shifting from direct nucleation lamellar exfoliation. Transmission electron microscopy (TEM) density functional theory (DFT) calculations confirm such transition driven by enhanced solute–solvent binding energy, which modulates pathway lead halide intermediates. Our findings provide valuable insights into solution-phase kinetics offer rational strategy designing optoelectronic properties, facilitating their scalable integration advanced semiconductor applications.
