Spin‐Coated and Vacuum‐Processed Hole‐Extracting Self‐Assembled Multilayers with H‐Aggregation for High‐Performance Inverted Perovskite Solar Cells

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(45)

Abstract We report a highly crystalline self‐assembled multilayer (SAMUL) that is fundamentally different from the conventional monolayer or disordered bilayer used for hole‐extraction in inverted perovskite solar cells (PSCs). The SAMUL can be easily formed on ITO substrate to establish better surface coverage enhance performance and stability of PSCs. A detailed structure‐property‐performance relationship molecules established through systematic study their crystallinity, molecular packing, hole‐transporting properties. These SAMULs are rationally optimized by varying structures deposition methods thermal evaporation spin‐coating fabricating CbzNaphPPA‐based was chosen PSCs due it exhibiting highest crystallinity hole mobility which derived ordered H‐aggregation. This resulted remarkably high fill factor 86.45 %, enables very impressive power conversion efficiency (PCE) 26.07 % achieved along with excellent device (94 its initial PCE retained after continuous operation 1200 h under 1‐sun irradiation at maximum point 65 °C).

Self-assembled bilayer for perovskite solar cells with improved tolerance against thermal stresses

Nature Energy, Год журнала: 2025, Номер unknown

Опубликована: Янв. 6, 2025

The adoption of perovskite solar cells (PSCs) requires improved resistance to high temperatures and temperature variations. Hole-selective self-assembled monolayers (SAMs) have enabled progress in the performance inverted PSCs, yet they may compromise stability owing desorption weak interfacial contact. Here we developed a bilayer by covalently interconnecting phosphonic acid SAM with triphenylamine upper layer. This polymerized network, formed through Friedel–Crafts alkylation, resisted thermal degradation up 100 °C for 200 h. Meanwhile, face-on-oriented layer exhibited adhesive contact perovskites, leading 1.7-fold improvement adhesion energy compared SAM–perovskite interface. We reported power conversion efficiencies exceeding 26% PSCs. champion devices demonstrated less than 4% 3% efficiency loss after 2,000 h damp heat exposure (85 85% relative humidity) over 1,200 cycles between −40 85 °C, respectively, meeting criteria outlined International Electrotechnical Commission 61215:2021 standards. To improve tolerance against variations, Dong et al. cross-link two molecules charge transport strengthen

Spontaneous bifacial capping of perovskite film for efficient and mechanically stable flexible solar cell

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Янв. 2, 2025

Flexible perovskite solar cells (F-PSCs) are appealing for their flexibility and high power-to-weight ratios. However, the fragile grain boundaries (GBs) in films can lead to stress strain cracks under bending conditions, limiting performance stability of F-PSCs. Herein, we show that film facilely achieve situ bifacial capping via introducing 4-(methoxy)benzylamine hydrobromide (MeOBABr) as precursor additive. The spontaneously formed MeOBABr layers flatten boundary grooves (GBGs), enable release mechanical at GBs during bending, rendering enhanced robustness. They also contribute reduction residual passivation surface defects film. Besides, molecular polarity result band favors interfacial charge extraction. corresponding inverted F-PSCs based on nickel oxide (NiOx)/poly(triaryl amine) (PTAA) hole transport bilayer reach a 23.7% power conversion efficiency (PCE) (22.9% certified) AM 1.5 G illumination 42.46% PCE 1000 lux indoor light illumination. Meanwhile, robust durability device is achieved. flexible limited by films. Here, authors in-situ demonstrate stable devices with maximum 23.7%.
