Advanced Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 7, 2025

Wide-bandgap perovskite solar cells (WBG PSCs) have promising applications in tandem devices yet suffer from low open-circuit voltages (VOCs) and less stability. To address these issues, the study introduces multifunctional nicotinamide derivatives into WBG PSCs, leveraging regulation on photovoltaically preferential orientation optoelectronic properties via diverse functional groups, e.g., carbonyl, amino. Isonicotinamide (IA) molecule emerges as most effective agent, enhancing crystallization kinetics defect passivation due to its unique planar spatial configuration. Incorporating IA perovskites improves (100) preferred crystal orientation, reduces trap density, enables well-matched energy band alignment. High-performance 1.77 eV PSCs are achieved with a champion power conversion efficiency of 19.34% VOC 1.342 V, leading fabrication best-performing all-perovskite cell PCE 28.53% (certified 28.27%) excellent operational stability, maintaining over 90% initial under 1 sun illumination for 600 h.

Abstract Well‐engineered buried interfaces play a pivotal role in achieving high‐performance perovskite solar cells (PSCs). A superior interface involves controlled crystallization, efficient charge transfer across interfaces, and robust interfacial bonding. Here, class of innovative additives, benzoyl sulfonyl molecules including 4‐sulfobenzoic acid monopotassium salt (K‐SBA), 4‐sulfamoylbenzoic (SBA) is introduced to tailer the SnO 2 /perovskite interface, aiming meet these essential criteria. Among them, K‐SBA performed better. The findings reveal that functional groups establish interactions with both perovskite, leading effective bilateral passivation mitigation stress. This results formation pore‐free high‐quality films substantial crystal sizes. Consequently, PSCs incorporating exhibited notable increase efficiency, 24.56% efficiency compared control device's 22.27%. Furthermore, K‐SBA‐enhanced maintain 90% their original even after 500 h maximum power point tracking. work provides valuable insights for further refinement advancement PSCs.

Anti‐Solvent‐Free Preparation for Efficient and Photostable Pure‐Iodide Wide‐Bandgap Perovskite Solar Cells

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(17)

Опубликована: Март 4, 2024

Abstract The perovskite/silicon tandem solar cell (TSC) has attracted tremendous attention due to its potential breakthrough the theoretical efficiency set for single‐junction cells. However, perovskite (PSC) designed as top component suffers from severe photo‐induced halide segregation owing mixed‐halide strategy achieving desirable wide‐bandgap (1.68 eV). Developing pure‐iodide perovskites is a promising route fabricate photostable TSCs. Here, we report efficient and PSCs made an anti‐solvent‐free (ASF) technique. ASF process achieved by mixing two precursor solutions, both of which are capable depositing corresponding films without involving anti‐solvent. mixed solution finally forms Cs 0.3 DMA 0.2 MA 0.5 PbI 3 film with bandgap 1.68 eV. Furthermore, methylammonium chloride additive applied enhance crystallinity reduce trap density films. As result, PSC delivers high 21.30 % excellent photostability, highest this type method significantly improves device reproducibility compared devices other anti‐solvent methods. Our findings provide novel recipe prepare PSCs.
